doing some research out of pure curiosity. im wondering if having no muff at all is more beneficial than a perf muffler. ive read that it hurts low end but helps high end for n/a motors. true or diff for VQ?

 

In the market fort a muffler huh bro.

SEARCH. THere is an entire thread dedicated to what mufflers to consider.

That being sd, I bought a 4" fireball muffler from ebay and its so killer. NO LOSS in low end torque. Car redlines much easier and sounds sick. At idle it is quiet. From 1500 to 3500 rpm it hums (growls) nicely but not loudly. It comes with a removable silencer if u want quieter but its not drone or annoying in any way. I took of the silencer off when first installed cuz i wanted to hear it w/o the silencer to decide if i needed it. DOnt need it. Everyone liked it. Sounds like a greddy but to me better. (my boy has a greddy)

HEre is the best part....muffler cost me 20 bucks online . I HAD to buy it lol and its the best 20 bucks ever spent. Jus dont forget to get hangers.

Im thinkin about the y-pipe and headers mod, but with the muffler and the short ram intake the car breathin so right and balanced I DONT want to mess with it

 

And yes, too much flow will hurt low end but help on the high end. Im tellin u man SEARCH. We had a big discussion about this.

 

i was just curious about the muff setup. me personally i want the megan cat back. along with a y pipe. buts that kinda a lot of money to me so i gotta wait a while.

 

See man...a lotta ppl on here will say go bigger. Stock pipe is 2" dia. Afermarket is 2.5" dia

IMO, i dont think bigger is better. U jus want better flow. Bigger pipe is better on the high side but it makes the low side suffer.

On my first max, i had a dybomax high flow muffler and a glasspack resonator. I dont mess with the Cat cuz its too much of a hassle at inspection time. Plus im kinda against polluting the environment lol. That setuip had too much flow and the low side suffered. The 4" fireball i got now, gave me more flow on the high but kept the flows on the low side fast enought such that i didnt notice any loss on the low side. I dont wanna mess up the flows cuz it breathin nice and sounds killer too.

My advice, jus get a bullet muffler and call it a day. If u want to be more aggressive, get the Y-Pipe first. Then if u still want more, then do the catback. But im pretty sure u will be happy with jus the y-pipe setup.

 

and go Stainless steel for whatever u buy. Much better material YAH!!!

 

It would be impossible to get through an inspection with no muffler at all. Some places even question after market exhaust systems.

 

+1

 

well 1) i just got my inspection done so i would be good for a year 2) if i was going to do it, id do the washer mod and 3) im not doing it bc its a ****ty way of doing it, i was just curious. i wanna set up my car right.

and for the record i just want everybody to know how badass it is that we can get a $200 part (y-pipe) and have a drastic change. i freaking love that.

 

wrong.

[edit]I'm removing, the useful information in my post, I'm very tired of seeing these threads pop up.

S E A R C H

Before purchasing this car in April, I knew NOTHING about exhaust, everything I learned is from the .org's stickies right here in the 4th gen section (also the 5th gen section).

no muffler = no class

 

^^^i must have no class because i'm running a straight pipe that replaced my ricer fart can which now sounds better than that can...

 

Good read. Thats why i dont go bigger pipes. Jus try to elimante the major source of backpressure: namely the super restrictive OEM muffler!

 

erm? might want to check the pre-cats. afaik they're by a long shot the most restrictive part.

 

I dont have pre-cats. Im fed spec.

plus i dont mess with the cats. Too much hassle during inspection time

 

Yes, you do. The OEM y-pipe and and two pre-cats inside it are the most restrictive parts of the OEM exhaust system, by far. That's the major source of backpressure in the system.

You don't have a pre-cat in the exhaust manifold, but you do in the y-pipe.

The OEM muffler? yeah it's probably not the best thing around, but it's very far from being "super restrictive". People who replace it do so for sound.

 

 

if you want something better than stock that doesnt sound like ***, buy a 5.5 gen muffler, better flow and no extra sound.



lol no pre cats.

 

OOOOOO....u are referring to the two diffusers on the y-pipe where the exhaust flow opens up then contracts. Ok i know what u guys talking bout now. Pre-cats for short huh lol. I thought u were talkin about the cali spec cat on the y-pipe.

I can only speak from experience, and everytime i replace the OEM muffler, i have seen better response from the car. I have never done the y-pipe mod so i cant attest to it.

Im not getting involved with SOnicCrush...when it comes to exhaust and backpressure, its better to jus listen to him lol

But naw, i dont mess with the three way cat.

 

the 3rd gen muffler was cool too. But i want my car to have an exhaust note. Stock 4th gen maxi is too quiet for me

 

Cashoit, search for Dynomax mufflers, that's what you're prolly looking for. Cheap, high flowing and people seem to like em. There's two versions, one is quiet and the other one isn't, I just can't think of the names of each version now.

 

I had a dynomax super turbo street on my previous 4th gen. They ok. plenty of flow, but the car felt sluggish on the low side. And no sound

I recommend the 4" fireball bullet muffler im running now. Great range of performance and sound

The next performance mod i do is prolly gonna be the y-pipe. Right now im workin on the exterior . IIYAK keep raggin about my hubcabs lol. Savin up for some rims

 

 

i went from completly stock to:
warpspeed ss y-pipe -> high flow cat (from warpspeed) -> bosal b pipe -> magnaflow muffler.. ( not the best setup but i was on a budget)

for the first few weeks i loved the sound it made, but after a while i got tired of always hearing the exhaust; especially in city driving.

w/ my second maxima im keeping it all stock. i will prob buy a y-pipe again but those dont really add any sound but do actually add some hp.

if you want a cool sound i say go on ebay and buy an intake. I like the growl of the intake much more than the rumbe of the exhaust.

just my 2 cents....

i got way more compliments from people about the sound of my car when it was completly stock.


i would say try ur car w/ no muffler for a little bit and see if you like it. some people love the sound and other people hate it. If you like the sound but not the tone id say go aftermarket. otherwise go "oem".

 

i dont think he shd go no muffler....at least install a glasspack back there

 

im running now 3 inch ypipe straight piped 2 1/2 no muffler, just a resonator and it sounds great and pulls a lil better uptop

 

edit i did get pulled over alot cause it was loud when ripping on the car

 

yeah. there are small catalytic converters in there that are supposed to augment the main cat before it warms up. It's not just an expansion chamber.

 

 

In philly, o yea i bet u did.

 

i ran just straight 2.5 piping into a greddy evo 2 and its quiet in idle but once it hits about 35 gran the car sounds nasty. but if your worried about back pressure i would leave two upper cats by the headers on and remove lower cat res and muffler and then do something. only downfall to a straight pipe that i have seen is a cackel on the down gearing

 

eewww, did you just really say that. glass packs sound nasty, my no muffler straight pipe replacement sounds wayyyy better than a freaken glass pack...

 

for the love of my ears please keep a muffler on your car and dont be THAT guy with the loud a$$ car that sounds like crap with the driver that thinks hes cool. I love asking those idiots if they got a hemi in that thing lmao
