today i had my muffler shop weld me up a custom 2.5 in. catback exhaust. i went with the dynomax super turbo muffler. all the while i was waiting for him to get done, i just kept thinking about how it would sound. finally, after paying the 150 for everything, not including muffler, i started it up in the shop, and it sounded beautiful. real nice low rumble at idle, and now i cant wait for the y pipe, which is my next performance mod. I've got a 3.5 inch tip on it, and it looks really nice. I was going to take pics, but it's been raining cats n dogs today, so ill wait til tomorrow. I just wish it was a little louder above 2800, but i still like it. my hacked airbox takes over at that point anyways.

 

150 is good price, is it crush bent?

 

What shop did you go to?

I'm glad to hear the good news about how yours sounded. I got my dynomax super turbo muffler in monday and got my cattman y-pipe in today so i'm having my local muffler shop put those on friday along with a custom cat-back 2.5 inch so i'm excited to hear what it sounds like and see how much of a difference it makes in the performance if any...

 

95custommax, i went to wittrock here in sheboygan. they do a good job with custom exhaust set ups. I believe it was crush bent, used a machine to bend all the piping into place. He's great with just eyeing it up and putting it into place. i figured 210 total wasnt a bad price for everything. I'm going to get a budget y pipe one of these days, and I hope it increases the idle tone. I opted not to have the exhaust resonated, so we'll see how the y pipe makes a difference, and whether or not ill need a resonator.

 

Wow $210 for everything.... other than the sound, do you seen any increase in performance?

I dunno, my previous stock exhaust was rusted through, so it may seem just like a mental thing, but it seems to get up faster than before. My speedo climbs faster than with the stock exhaust. My B-Pipe was falling apart, and the mechanic pulled a small rock out of it, and the muffler was shot. So maybe restored it, but nothing significant. Havent had the chance to open it up and find out since it's been raining here. Maybe later this afternoon it will clear up.

 

Keep us posted. That sounds like a good deal. I'd like to hear if it gets too noisy when your are hard on it.

 

wow, i'm glad u like it!. Do you hear any raspyness at all? I just ordered budget b-ipe resonated and a dynomax turbo muffler...i'm going wit a resonated 2.5" straight since i cant find regular 2.5" resonated, and i have warpspeed y-pipe.

 

[QUOTE=eckohb] I believe it was crush bent, used a machine to bend all the piping into place. QUOTE]

Is that crush bent or mandrel bent? Mandrel is the way to go:

"The Exhaust Pipe
To save cost, a typical stock exhaust uses small diameter, crush bent pipe. Crush bends are easy to make in mass production. However, crush bends can reduce the flow of a pipe by up to 50 percent. A typical exhaust system made by the local neighborhood muffler shop is also crush bent. The best exhaust systems, like most pre-made exhaust systems, come with mandrel bends. Mandrel bending is done by a special machine that uses a non-crushable insert or mandrel that goes into the pipe while bending to prevent it from becoming crushed. "

sounds exactly like my setup, 2.5" custom catback with dynomax super turbo muffler and 3.5" tip hehe

sounds good, just definatly need a resonator with this y pipe

 

i took it out today and got on her, and the exhaust noise dissapears at around 2800-3000 rpm. Not raspy at all. Like I said, performance is minimal if any, but still sounds nice, and looks good too. like i said, it might seem faster just because it sounds louder, but who knows. Now just gotta get that y pipe and put it all together. i'll dyno it then and see what results came from the y and exhaust

 

I doubt he has mandrel bends as very few shops actually have mandrel machines. On a N/A car mandrel bent piping makes almost no difference.

 

That depends. If someone has a na maxima for example:
1) Get's a 2"-2.25" cat back put on and it's crushed bent, it might make a significant difference. Especially if the crush necks down the dia by 50%

2) If that same person got a 2.5" catback, the same crush won't affect flow as much as it's a bigger pipe to begin with.

Your statement depends greatly on how much the bend is "crushed".

 

Ok, first off, you'll need a resonator once the ypipe goes in. TRUST ME, it makes a huge difference. I payed $100 for the piping and welding for my bpipe. But it was $60 later for the resonator. If i would have done it all at once it would have been even cheaper. Total cost for catback = $300 (Muffler, Bpipe, Resonator, installation).

 

Let me clear it up a bit, I hope. Lets say you and me go to a muffler shop and have 2.5'" cat backs installed. Only thing different is that yours is mandrel bent and mine is crush bent. You should see maybe a 1 or 2 hp advantage over mine. Knowing that a cat back itself only gives 4-5 hp on a N/A application it's not that much. Then again the 4hp you get is 100% more than what I got. The gains are so minimal that it won't make much of a difference.

 

yeah, all of you have been used to paying out the butt for these car parts. I mean, the manufacturers are just r a p i n g us left and right.

I paid $50 for the whole 2.5" custom b-pipe. I already had a muffler, so that was it.
That is what it should be, not any of this $150 to bend some pipe. Man, I try to tell everyone this that I can to help save some of my Maxima friends some money, but I guess some people just get too ancy and want things right then.

 

i put a borla pro xs muffler on the back of my car that hooked up to a budget b pipe with res. i had to order 2.5 in. stainless steel piping and have a flange put on it to bolt it to the b pipe. the pipe was hooked to the muffler with exhaust clamps. the muffler shop i went to had a mandrel bender which i watched the guy use to form the piece of piping that went from the b pipe to the muffler.

$65 Borla pro xs muffler
$40 2.5 in exhaust tip
$20 2.5 in polished stainless steel piping

fortunatly i knew the mechanic and he gave me the exhaust clamps and did the work for free. (i think i gave him like 40 bucks, but that same day he replaced my rear roaters and gave me free rear break pads all for free.)

anyway i had this cat back set up before i put on my y pipe and i noticed a lot of droning even with the resinator. after i put the y pipe on instead of getting worse, the sound was much better and the droaning went away. the exhaust note got lower and it sounded better as a whole once the y pipe was on. ps. i wrapped the budget y pipe with exhaust wrap before i put it on. on not sure if this affects the sound since ive never heard it with it off but it seems like it could muffle potential sound coming from the flex joint.

 

thats what im scared of, the y pipe making the exhaust sound too raspy or too loud. i asked the dude to have the b pipe resonated, but he said it would make the exhaust quiet, and right now, with a resonator, the exhaust would be really quiet. so i figure it'll be worth the 60$ or w/e once ig et the y pipe to throw a resonator on there. we'll see how i like it.

 

anyone have sound clips of an exhaust set up similar to mine plus y pipe?

 

cmon, someone has to have a similar set up with a sound clip. im going to get the y pipe no matter what, i just want to find out what it sounds like before hand. pretty please?

 

yeah, but if he just crush bends it, is there really any point? and do you wish you would have resonated it? or is it ok?

 

Ive only had my max for 2 weeks now, but i had to replace the alternator so i got a quick glance at the exhaust. It looks like a pretty straight piece of tubing. There is no way that on a na 6cyl putting out 190hp there is gonna be a noticable difference between mandrel bent and crush bent. None of the bends are severe enough to really warrant the extra money. Also theres not even really any need for a full stainless setup IMHO. A stock exhaust usually lasts at least 10 years. Our cars are anywhere from 5 to 10 years old. Realistically, are you still gonna have your Max in 10 years? Do you really need an exhaust that is gonna last 20 years? Sure they look pretty, but when was the last time you found yourself crawling on the ground to admire how shiny your exhaust piping was? Money can be more efficently allocated elsewhere. Anyone that dumps $600 into a cat back is either very rich or needs their head examined.

 

ecko, if you get a ypipe, it would be very wise to put a resonator on that b-pipe or your car will sound like a typical riced out import. It's an awful sound that is output, and extremely loud. Idle sounds fine, but when you drive its very annoying, and when you go WOT its just embarrassing.

 

ok so if i get a custom b-pipe made up at a muffler shop, how do i get it resonated? will they be able to just put any resonator in there?

 

eckohb i have a warpspeed y and a dynomax superturbo but with a stock b pipe. if u want a sound clip tho just let me know

 

hey if you looked for a 2.5" resonated b-pipe i got mine from warpspeed. just give them a call. maybe they dont offer it anymore??? this was over 1 year ago.

-rafal

 

does anyone know where i can find a resonator that will fit in the stock place? i cant seem to find one.

 

i am putting a custom b-pipe on my car to 40 series delta flow muffler. do you think it would be a bad idea to leave it un-resonated?

 

i have a stillen y-pipe, btw

 

i did the same thing.but kept the stock muffler.. it doesnt matter if its crush bent if your NA on 2.5 inch piping..the real restriction is the part right after the resonator where the pipe is bent in half n the stock piping.. otehr than that, as long as your max is NA, 2.25 crush piping would still be sufficient.

 

I have a Budget cold air system, y pipe and b pipe with a resonator. Sounds very good when you jump on it hard, go easy and it's quiet. I think with out the resonator it would really be to damn noisy......I like to sneak up on the yuppies in thier bemmers..p.s. the y-pipe made the biggest jump in power, the others just help some.

 

do you know where i could find a universal resonator that would fit in the stock location? i cant find one.

 

cant the muffler shop make one for you?

 

they can just make a resonator? isn't it a semi-muffler? how would they make that?

 

they asked me if i wanted mine resonated, so i assume it's possible. i knew they weren't talking about using the stock one, seeing as how it rusted through. maybe they had resonators they could use, but i was given the option with mine.

 

Just use a Cherry Bomb muffler for the resonator. You can pick those up cheap too.........

 

does that work? i know they would fit, but wouldn't that sound kinda weird with the flowmaster on there also?

 

Guttermouf, the custom exhaust shop should have everything you need such as resonators, clamps, etc. I believe aftermarket resonators come in all different length and sizes so I guess you just have to ask.

 

what would be an ideal length for a resonator for my set up once i get the budget y pipe?
