I did a search with little success. I've seen that my options are Warpspeed, Stillen and Cattman. Are there any others out there? Cost is a consideration. Budget's site doesn't show a version for an 03. I have a B-pipe that I'll probably throw on, so what are the pros and cons of a Y-pipe and B-pipe upgrade? I'm primarily worried about the "bees in a can" sound droning on while I'm driving normally. Under WOT I expect to hear a difference, but I don't want to hear an annoying drone while I'm in traffic or on the highway. Any experience is appreciated. Please note where you got your pipe and for how much. thx

 

I have a cattman. There is no felt gain, but it does sound way better.

 

I did the y-pipe and noticed some better performance. Also, it sounds nice- no bees whatsoever. I also saw a small increase in my MPG's. Got for it...

 

Thanks. Where did you get your Topspeed and for how much?

 

I paid 150.00 shipped!! IIRC, you can't get them anymore

 

with a cattman y and intake i dynoed 218HP/228TQ. does it work, yeah, its it worth the 5-7 HP for the $350 I spent, no. Get headers..

 

the y-pipe doesn't do much for the 3.5.. more effective on the 3.0...

Go headers!

I just put on a cattman y-pipe on my 3.0, no bees in the can sound, but I got noticable gains, plus made the engine sound a bit meaner...

 

Thanks for replies, please keep them coming. Do I have a choice besides Cattman, Warpspeed and Stillen? Does anyone have a Waspspeed and did you have any fitment issues? I realize headers get more gains, but I really don't have the cash right now.

 

Im not sure but by your comment "I dont have the cash right now" makes it sound like you want the headers but cant afford them, if this is true you may want to save up to get the headers, I think you would be happier in the long run.
That said I have a warpspeed (Stainless) I got for 250 shipped. No problems at all. Sound is a little deeper,more power noticed as well, but I cant speak for 3.5 engine though.

 

Topspeed pipes are discontinued, i remember me gapp, and jdmaxima89 bought the last batch i belive. These were for 00-01's anyways so it wouldnt concern you really.

Save your cash for headers as others have stated

 

Whoever says y-pipes on a 3.5L sound good have never heard equal length headers.

 

headers FTW on the 3.5L

 

I heard that the Y-Pipe is suppost to add like 10-12 horse power and the headers only give u like another 5? because i was thinking of doing just the y pipe without the headers

 

for 2k 2k1 ypipe is the best bang for the buck hands down. if you can afford it headers will give you more gain though. You should really do some research...this topic has come up atleast 100+ times

 

Does anyone have any experience with Aluminized steel vs. Stainless steel? I realize that stainless is better, but is it worth the price difference? I don't have issues with rust in my area. Has anyone tried the RedlineMax y-pipe?

 

search man this topic has been discussed a lot. trust me you want the SS if you plan on keeping it for a while

 

As my original post says, I did search and didn't find much for the 5.5 gens. There is plenty of crap on the 4th and 5th gens which doesn't apply to me.

 

While I appreciate all the comments from the noobs trying to boost their post count, it doesn't help me. Also, the folks selling 00-01 y-pipes don't help me either.

Does anyone have any experience with an aluminized Warpspeed? Quality, fit, sound? Sound quality in combo with a B-pipe?

 

I bought a w/s alum. one and it did not fit right, i have a greddy evo 2 cat back and my exhaust was all out of alignment and it was so tight you could not even move it at all (no flex) I sent it back. Oh and the exhaust was a whole lot louder to.

 

get a ypipe, if not buy headers !

 

Posts deleted.

I used to have a Cattman y-pipe and the quality of the piece was immaculate. Installation was a breeze and it fit perfectly with my Frankencar catback. There were gains, but not much (butt dyno). Not sure if that's what you wanted to hear, but since I'm one of the few with y-pipe experiences on a 5.5 I just thought I'd throw it in.

Btw, I think Hoooper has a WS y-pipe on his 5.5, you could try asking him for an opinion.

 

Thanks for the info, puppet. Your install directions on your website should be very helpful when I finally get a pipe. Anyone else have a Warpspeed y-pipe?

 

Go headers. y-pipe is a waste IMO on the 5.5 gen

 

Thanks again but I don't need opinions from 00-01 owners. Any 02-03 Warpspeed owners out there?

 

I have WarpSpeed y-pipe. It fit great, sounds great, and great price.

 

Thanks. Do you have the stainless or the aluminized?

Anybody with a b-pipe combo?

 

I've heard that a Y pipe and B pipe combo can be loud.

 

so people with 3.0 engines dont know what they are talking about and have nothing good to add?
especially a member with way more posts so he knows more about your engine then you do

 

Back up buddy. Read my posts again. I never said that 3.0 owners don't know what they are talking about. I want to hear from 3.5 owners and their personal experiences, not from people just giving opinions about cars they don't own. I don't give a crap how many posts you have unless you have something constructive to add.

Stop picking a fight and move on if you have nothing to add.

 

He(Mass_Media) has owned an 02/3, and has dynoed w/ HS headers. Read past the 2001 in his information. (540i)

Here's a knowlegable members' testimony on a 5.5g y, as well as a few others.
http://forums.maxima.org/showthread.php?t=217191

Even though it's not a cattman, the same still stands for cattman since no 5.5g y-pipe is equal length.

 

Thanks for the clarification on Mass_Media's qualifications. Had I known that he had owned a 5.5 gen then I would have re-phrased my response. No disrespect intended. That being said, I'm not disputing the obvious benefits of headers. At this point, I prefer to take the long way and try a cheap y-pipe with a b-pipe first. Call it stupid, crazy or whatever. Thanks for all the helpful responses so far.

If you have a cheap y-pipe for sale, please speak up.

 

i tried to tell you that he knew what he was talking about but you just tried to flame me

 

I don't flame unless I get flamed first. This can go on all day because we obviously have nothing better to do than cruise the org. Let's just call it one big misunderstanding and move on.

 

can you please explain how i "flamed" you? i simply made the point that you were blowing off a person smarter then you just because he didnt have the same engine as you.
you got upset cause people werent telling you want you wanted to hear. a y-pipe is pointless on a 3.5. not worth the work to install it. but since you seem to know all, do whatever you want. why ask a question if you are already convinced that you want to do it?
and yes, we can do this all day (until your thread gets locked) since im off work today.

 

Please don't make assumptions about someone's intelligence while typing on a keyboard, it can bring your own into question. Also, you may want to work on your grammar.

 

inside voice dude!

 

OK just to clarify 2k- 2k1 y pipe good to do opposse to headers
2k2 -2k3 headers because the precats are IN the headers thus giving u full potential
can somebody confirm my assesment please
blade I dont mean to jack ur thread dude just wanna get same info thanx

 

He mentioned he already tried to search in his first post..

I dont know man...I just got a cattman rear section only for my 03 6m/t and only noticed a slight increase in power. Im also looking into either a y-pipe or a b-pipe replacement. The shop that did the install (its an exhaust shop) suggested that I get a part in between the rear section and the cat, which is the b-pipe if Im not mistaken. he said with that I will get the real increase in HP b/c back pressure is reduced.

I would stick with Cattman

 

you are correct


he jacked his own thread

 

Oh dear God....


save up for headers.
