I'll start off with sharing my setup exhaust wise:

2.5" Mandrel Bent WSP Y
Stock Catalyst
2.5" B-pipe w/no resonator
Flowmasters camaro muffler
2.25" Dual pipes leading to each end of bumper.

Right now my setup sounds really deep and aggressive. However, sometimes it will get loud and tinny, such as when I'm in second gear and give it gas at around 2.2k rpms, it'll be blaring loud and high pitched, until it takes a couple upshifts into gear and then quites to a very deep purr. Me and Chaz are getting a 5spd swap for my car soon so those annoying upshifts will be non-existant, unless I give it gas in second gear w/o downshifting I guess.

If I exchange my 2.5" b-pipe for a 3" b-pipe, would I notice any change in exhaust note? What about if I got with a 4" b-pipe? Keep in mind I would leave everything else the same.

As for the low end punch...my friend with a 2000 V6 5spd stang has dual 4" straight pipes leading into 2 free flowing mufflers and hasn't noticed any lag down low verses the stock setup. Would this hold true to Maxima 5spd's as well? They seem to not be affected by lagchargers and other things like Auto's are.I guess the best example would be Sx7r and his setup.

So in the end, would a 3" bpipe give me a noticable deeper tone throught the power band, or would a 4"? And would I notice any power lag down low even when I get my 5spd in?

 

do you have a soundclip of your car? i never knew you had flowmaster mufflers i am having mine with the dual tips (same camaro style) done in about 2 weeks... cept my exhaust will be full stainless everything minus the muffler

 

No I wanna get sound clips of my car so bad but I don't know how to.

Didn't you email me about this? I got an email about a guys question and it sounds very familier to what your doing..

 

lol yea it was me... i asked about the bumper cut out.... well i finally got the money up to do this... so i will be joining the dual club soon..

 

The blaring is probably from the length of the pipes after the muffler - think trumpet. A resonator at or near each tip would help.

 

CM, it's your Y-Pipe that is causing the rasp/tinny sound, even if you get a 5spd swap, you'll still have the rasp/tinny sound.
Solution is to get a resonator after the Cat, before the muffler.

Went through the same thing w/ geomax's car, once a resonator was installed, quieted down his system, and got rid of the rasp/tinny sound.

Why Bother w/ 3" or even 4" ???

Leave it alone and get a resonator

-Peace

 

hmm..i've come to the conclusion that now my exhaust leak is gone, i like my exhaust but i need to quiet it down..i've noticed, i have a very raspy/tinny sound when i rev it out..i love that sound because to me, it sounds like my friends dads 02 ///M3.
anyway..i plan to change my muffler from a straight thru tanabe racing medallion to a Ractive MT217C (black, oval, (2) 3.5" tips, center inlet). will i lose this tinny sound?

 

GET A RESONATOR~!

 

not yet..new muffler first (i hate this one and it looks funny tucked so far under the bumper). then if its still too loud, i'll get a cat. then, resonator.

 

if you get a cat, it won't cut any noise, and you might as well get a resonator.

 

Hogan,

I was told that even a 3" b over a 2.5" b would increase depth and volume of the sound. Could you please tell me why a 3 or even 4 inch b-pipe would do nothing to increase burble/depth ?

Like I said I love the way she sounds, but it's when i'm in certain gears or certain RPMS it just gets raspy until shifts or speed changes are made. I guess your right about the turbo tube (resonator), but I would lose some power and it would probubly make the car sound too quite and what not at low RPMS.

I love the low end burble and aggressive sound, even got a compliment from a Nissan dude who drove it at my service check..but I guess the only way to cure the certain raspy points is to muffle it down with resonation, which in turn also takes away some of that aggressive burble at low speeds.

I was thinking of combining a turbo tube with a 4 inch b-pipe, that way I get alot more depth/burble with the tube quiting down the Y-pipe..best of both worlds..but you seem to be against this idea..maybe becuase of the low end punch that would be lost..I donno.. please share you knowledge with us.

 

Craig, you addressed a rasp, which is remedied by use of a resonator. Anyhow why would you want to go 3.0" or even 4.0" w/o a resonator, your exhaust tone will sound like crap. If want to go all out, get free flow canister style mufflers, and go dual 2.5".
Guess what ? You still need a resonator, the Y-Pipe is causing that unwanted rasp.
THE RESONATOR WILL NOT MAKE YOU LOSE POWER~!~!
A resonator will not quiet down your system to the point you can't hear it. Resonator might enchance your low end burble along w/ getting rid of the rasp from the Y-Pipe.
I suggest you not do any rediculous thing as have a 4.0" Mid Pipe made. I can care less about low end losses, your OBJECTIVE IS SOUND, so stop getting the two mixed up.
Also you won't get a deeper tone w/ a bigger pipe, you get more sound volume, so you may get more rasp, get a resonator and call it a day and save yourself about $100+ in headaches. If you want to get a 3.0" or 4.0" mid Pipe w/ a resonator, by all means get one, and then tell us about how your car sounds.

-Peace

 

A 3-4" pipe would probably make you lose power as well. In general as you use more, different sized pipes you are causing considerably more turbulance and pressure drops along the exhaust. 3-4" is also bigger than what most boosted Maximas run so unless you are going to have something that needs less restriction (NOS, s/c) you don't need that big of a pipe. The Law of Continuity says A1v1 = A2v2. As you increase the cross sectional area you decrease the velocity of the gases. Think about what happens when you squeeze a water hose.
-hype

 

craig mack, it says your car is black but looks blue...u changed the color?

 

Nah...its black..always been black. Tons of people have asked me this..but I have a fairly new bumper and hood so they are really shiny and I guess that could cause it to look blue when the sun reflects off it.

 

If I wanted to get a sound clip of my exhaust, how would I go about doing it? What do I have to buy ?

 

A 4" B-pipe is WAY too big. A single 3" pipe can easily flow a 350hp LT1. 4" is more for NA cars pushing 400+hp and/or running a massive turbo. 2.5" is ALL you need. Get a resonator and get resonated tips. Your sound will be much better and you're not gonna loose any power.


Dave

 

I know the 3-4" is not NEEDED, but I'm talking about sound here.

So your saying that the dual 4" straight pipes on my friends mustang would sound no meaner and grumblier than if he had dual 2.5" straight pipes? That's where I got the idea from..

 

Just tape record it, and then play back the tape with an RCA cable connecting the Line Out/Earphones jack of the tape player to the Line In/Microphone jack of your computer's sound card. Your OS should come with a simple audio play/record program so you can record the tape onto a file.

 

Ohh yea, something like a camcorder...i'll do that sometime!

 

Er, RCA cables are stereo speaker-type cables, that's not what I meant. Just use your typical male/male audio cable (the kind with headphone-type connectors at both ends).

 

How about I just use my camcorder and record it, and when I'm ready to transfer it to the COMP i'll drop you an email iight

 

hook me up with that craig!

 

Whatever you are smoking, send me some. I know you guys have good hash up there.

I doubt he has 4" straight pipes, cause I looked underneath a V6 stang last night, and started to laugh on the dimensions of stock piping vs a 4" Tip from my "race pipe" set up.
I guess I can't come up with a good reason, beyond its totally unreasonable to put 3" or 4" Piping, so I guess you should do it, and post up a sound clip.

If you want obnoxious sound, route one straight 2.5" pipe out the right side after the first 90 degree bend before the rear beam suspension.

 

Your buddy with the Stang clearly has no idea what he's got. I know of NOT ONE SINGLE 5.0/4.6 Stang owner that's running 4.0" anything. I don't even think there's room under the car to clear 4" piping (it would scrap and hit the body/tunnel. There are 3" catbacks on the market for the V8 Stangs, but that's considered VERY excessive and only the turbo V8 and larger displacement Stangs are running this kind of piping. I doubt your buddy's piping is any bigger than 2.5". All he probably has is 4" tips. His ideal setup would be a dual 2" setup.


Dave

 

In other words...Dave B wants the same ish that Craig and his friend are smoking, like I said I looked under a V6 Mustang, and started to laugh.

I could use what Craig or his friend is smoking.

 

since everyone is saying to get a resonator to get rid of the rasp in a certain rpm range.... one where do i buy one, or will my exhaust guy have a hook up on it... and 2 will a resonating tip work any?? like a monza (by pacesetter) or something.... granted it will quiet it down a bit but wil a flow master 40 i am guessing that won't matter much

 

#1 Exhaust shop or performance shop or even PEP BOYS. Chain stores.
#2 NO.

Note: pacesetter tips suck donkeh nads.

Flowmaster or not, its still just a muffler.

BTW DynoMax outflows a Flowmaster, thats why I switched.

 

Dynomax outflows flowmaster? but how does it sound? cuza we all know that the differences in horspower for our exhaust so so small its almost negligable - so you can conclude that the most a person gets out fo exhaust is sound. But, don't get me wrong, if dynomax sounds like flowmaster and goes for an approximate same price i'm all for it. if it doesn't sound as good as flowmasters, then its flowmasters for me this summer...

 

He's probubly just BS'ing me. Your right he does have huge 4inch chrome tips, but he also said 4 inch piping. I looked under his car today and guess what, the pipes are ALOT smaller than 4 inches. Looked like dual 2"'s or 2.5"s...3" at the BIGGEST.

He has a 5-speed with STS, superchip, CAI, headers, downpipe, straight pipes, a throttle body thingy(I think), and some more junk. Believe it or not it's fast..he took me for a ride and when he changed from 1-2 it pulled me back in the seat like a ****. He chirped and did all those neat things.

Hogan, Dynomax might outflow a flowmasters by a little margin, but Fmasters is like K&N...tried and true. It also has one of the meanest sounds..

 

I used to have the HKS rear section and a custom 2.5" B-pipe with NO resonator. NOw that sh*t was LOUD!
ALmost too loud! But it was DEEP as hell too. I would imagine 3" b-pipe or more without a resonator would sound disgustingly loud...
RICER LOUD....no?

 

Well that setup would be MUCH quiter than mine, CAI, Y-pipe (biggest sound maker), 2.5 b, flow duals..it's loud, but 90% of the time deep and to my liking. When I come to stop lights and creep forward in traffic is when it's VERY deep and grumbly.


Well the guy who I bought the original set of duals from was Kirk, AKA 1/3there2/3togo...I didn't use his b-pipe or resonator. His setup consisted of a 3" b-pipe and resonator...he said it was quite a bit deeper/muffled than a 2.5" b with no resonator. I guess it's becuase of the resonator itself and NOT the 3" piping correct? That's where I got confused into thinking the bigger the better..

 

Yeah, I didn't 4" piping was possible on that V6.

I agree, the new V6 Stangs in 5 speed form are VERY capable of 14s with a few mods. With his mods, he can most likely hit upper 14s quite easily. I personally know a guy with a V6 Stang that went 15.0@92mph with headers, GT LSD, dual exhaust, and intake. That V6 will feel fast simply because it makes a bit more low rpm torque than we do. However, when you let these motors "stretch their legs" in the 1/4 mile, a 5 speed Maxima will start to walk that Stang simply because our motors pull longer and make more power. Torque can be a very misleading thing.


Dave

 

ok so i should make sure a resonator is stuck in with the bpipe then without a doubt... i don't want any raspy ricey sound at all... and

i am staying with flowmasters cause i have dynomax on my truck and it is loud and deep but my bro with the same engine hell same truck almost has the same exhaust with flowmasters and they sound soooo much better

 

Your right about that! It did punch me back in my seat noticablly more than my friends stock 5spd SE maxima...but it's not fair becuase the stang had a superchip, X-pipe and CAI at the time. Also my friend baby's his clutch and didn't shift near the RPM's the stang did.

I mean becuase stock they only have a 15lb-ft. torque advantage over us, and with a heavier body. I think stock for stock, same shift points, the Maxima could have the same feeling of power or more down low as the 2000 Rustang V6.

 

Craig, that was weak. Read below.

http://www.dynomax.com/aboutus.stm

http://www.flowmastermufflers.com/web10/MP_about.html

BTW the sound was alot smoother, deeper, and had a better "bark" when you crack the throttle off the line.

Don't get me started.

BTW post some pics of your friend's V6 Stang, would love to see this 3.8L V6 Monster that pulls you back in your seat.
