Anybody running a y-pipe with a factory catback? If so, any difference in exhaust tone? Which one is the best in your opinion? I will put a frankencar catback on sooner or later, but want to do a y-pipe first.

 

I definately noticed a difference. Added a nice low rumble. Not very loud at all though.

BTW, I went with the Cattman. It seems to be the best quality available as Im sure others will attest to.

 

I read many postings on this forum regarding this topic and it looks y-pipe mode without any other changes will make a difference, a noticeable difference. This seems to be the majority of the answers that i read here. I am planning to do one myself i the very near future.

 

I'm doing the Y and B pipe in a few weeks on stock exhaust including stock muffler.

 

yeah i've seen a bunch of talk about it...but most run a y-pipe with some other exhaust mods. trying to get some input from those who just have y-pipe with stock b-pipe and rear section

 

Thats why I responded. I dont have any other exhaust mods as of yet

 

i have read that the stock exhaust is not too restricting

 

yeah i've seen the same thing..only thing really restricting is the y-pipe..from there back is pretty solid.

 

The y-pipe and b-pipe both have some restrictive points, but the stock muffler and rear section flows nicely.

 

I wouldn't doubt it, my stock y and b pipe have holes now my cars sounds like a civic, car feel more restricted now with the holes. Can't wait for my parts to come in.

 

Does it worth it to change the b-pipe if I buy a y-pipe? Or just change the y-pipe?

 

I just got a y pipe stock everything else................franken car comming soon

 

i have Y pipe and b pipe on my stock muffler and i love it.. the sound is quite in cabin and at cruising speed ..
and a nice rumble at WOT kinda like the g35c sound..

no headaches from loud exaust

 

What kind of Y-pipe and B-pipe are you running?

 

No. . . . . . . . IMO of course.


G35c ???
I have headers on my 3.5L, and still doesn't sound like that, in fact you can't even tell I have headers or any engine modifications for that matter.

 

I have a Cattman Y-pipe and Injen CAI with stock exhaust (so far). It's only louder under WOT. Outside of that, it sounds close to stock IMHO.

 

warpspeed y and b pipe

 

i didnt say it sound EXACTLY like a g35c.. "KINDA LIKE"
its quite but there is a nice tone when u floor it

 

What exhaust set-up do you have?

 

warpspeed y pipe, and warpspeed non resonated b pipe and stock muffler.

 

Injen CAI, Cattman Y-pipe, stock Catback, it makes a lovely sound and noticeble improvement. The 1st mods to your car should be the Y-pie, then intake, then maybe b pipe. You change the muffler the sound WILL get louder, you change everything else, it'll still sound mostly the same.

 

i ran that way for a while and it sounded nice but not really loud. now i have an hks muffler and it just sounds sweeter. but running a ypipe with factory cat back does sound good. here's a sound clip of mine with a ypipe and gutted cat.

it makes it sound a lil like the g35 exhaust. a little more deep rumble. the only reason i got mine was cuz my precats were clogged

 

i have a y pipe with stock exhaust. at idle it makes a small bubbling sound, deeper than stock. if you want to sound like a G35, put a test pipe to replace the main cat and putting a B pipe after would be the nail in the coffin.

 

I have Injen CAI, Cattman Headers, and Cattman B-pipe. The car sounds almost stock under "normal driving" but, once WOT it turns into a beast.

 

If you want to make the G35's sound like wussazz cars put on headers, highflow cat (or test pipe) and a cattman cattback...

Maxima's sound mean as hell wide open.

 

my OEM flex pipe broke a week ago .. I installed the Pro-1 Top Speed Y pipe on mines.. Noticeable gains, alot more responsive now. no other mod besides a Drop in K & N

install was done in half hour

 

else is there .. bseides a muffler since you're doing a y & b-pipe?

Invalid posts

 

I have just a Warpspeed Y-pipe right now and it is definitely a little deeper at low rpms, but other than that it sounds the same. I love the slight rumble between about 1,500 - 2,500. Like a moron, I didnt install the hanger though, and at the track when i launched the flex busted so as of now mine sounds like crap. New triple-ply flex section is sitting here waiting for my warpspeed b-pipe to get here.

 

How about the stock exhaust manifolds and stock catalytic converter? If he got headers instead of just the y-pipe and if he got a test pipe to replace his cat, THEN you could say " else is there .. bseides a muffler since you're doing a y & b-pipe?"

 

But it was an invalid post since the original poster asked about y-pipe only

And we all know headers & Y are one in the Maxima world .. so him saying hes getting a y-pipe canceles out headers too.

 

You're exactly right...

That's why I said:

 

No I dont think so .... Headers cancel out y-pipe, since all header systems for the max come with y-pipes... Max manifolds are restrictive and heavy, getting rid of them is a huge bonus.

Considering new manifolds put more power to the ground than an entire catback does... I would not cancel them out. a header system puts down another 5-7hp over a y-pipe alone while you are lucky to see any gain with a catback.

 

Calling me a ? Hmm, well I stated that headers/y-pipe are one, meaing headers cancel out y-pipe if one has headers (system) ...

02+ gain more than 5-7 whp than just a y-pipe.
