I'm strongly considering ordering the budget y-pipe. I've heard that you get what you paid for, but aren't all y-pipes, at least budget and WSP, the same in performance gain? Moreover, I currently have the Frankencar intake with Greddy muffler. I'm not planning to add a S/C or a turbo. Will I lose some low end by getting the b-pipe along with the y-pipe. Is the b-pipe fix offered by WSP a good enough solution?

 

A b-pipe will give minimal gains on an N/A Max, maybe about 5 HP and most of that comes from removing the restictive S bend and crushed area behind the cat. The bpipe fix removes these two restrictions so it should give nearly the same gains as a full bpipe, but it may be easier to install a full b-pipe instead of trying to cut your stock one and attach it to the b pipefix. A bpipe should not cause any noticable low end loss, at least with a 2.24" one.

The gains from different ypipes are very close so it should not really matter. There where some complaints about the 'bees in a can' sound from some of the early budget mandrel bent Ypipes, I am not sure if this has been fixed, I would do a search and read up on it before I bought one

 

i definately think that any aftermarket ypipe/bpipe combo is a benefit to our cars. you might lose a tiny bit of low end, but the benefit is your engine revs up much quicker and the power up top is vastly improved for the money you spent. i really don't notice any lowend loss because the engine puts out so much anyway. i recommend a full exhaust from the ypipe back to compliment your intake.

 

When I first installed my JWT POP, I suffered from torque loss on the low end (like everyone else says). When I replaced my oem exhaust system with Budget's y-pipe, high-flow cat, Budget b-pipe (no resonator) & 2K1 Maxima muffler with 2.5" inlet pipe, I noticed two main changes:

(1) regained lost low-end torque;
(2) significantly more power from 3K to 6K rpm.

I've yet to dyno the car (probably doing it around Feb.) I'm itching to see the HP/TQ curves with the mods.

 

Thanks all. Does it matter if I go with a 2.25 or a 2.5 b-pipe? If the b-pipe is not to expensive, I may get it from budget as well.

 

i have the older non mandrel T304 budget ypipe and i'm still very happy with it. it's the same since i got it two summers ago. the courtesy bpipe i have is about 2.25 or 60mm. i'm not exactly sure. it's a little bigger than stock that's for sure, but it's not 3" piping. unless you're going forced induction anything less than 3" should be fine. for the least expensive but 100% effective setup i'd get a budget T304 ypipe, warpspeed alum testpipe, warpspeed alum Bpipe w/ or w/out the resonator, welded to a borla or dynomax muffler. my exhaust is pretty "unique."

 

Just got a budget Y, no bees here. They seem to have fixed the earlier problem.

 

how's your exhaust setup sound at idle,highway speed,and wot?thanx!

 

get a ypipe, and bpipe...an afermarket muffler is not really good for an increase in hp, only get it if you want the exhaust louder

 

I would say go with 2.5". My greddy was only 2.25 and now i notice a little more power with 2.5" and my true straight through muffler.

 

I'd suggest the same. I think stock exhaust piping is 2.25" dia. By going up another 0.25" diameter, your cross-sectional area goes up by 23.4%.

 

look up my original post titled "borla, the absolute perfect setup."

Really? I thought the Greddy's were 2.5"?

 

My current setup is pretty quiet. I can barely hear the exhaust. All I really hear is the intake at 2K to around 3K RPM. It makes a low growl sound which I like. It can get loud at times while crusing on the highway.

 

Since you already have an aftermarket muffler with the stock Y and B, everything seems OK now. Once you add the Y pipe, though, your exhaust is going to get loud. That's not to say that the Y is loud, it's the combination of Y and aftermarket muffler that seems to always produce decibels, the kind you don't want. If you want to keep everything NA, I would suggest you maximize your power potential by doing everything, Y, B and muffler. Maybe look into VQ drivers' setup, or replace your muffler with a 5th gen muffler. That way, you get the most power, but not alot of noise either, or nice noises, from your exhaust.

I'm going to get a bpipe, but keep my stock muffler. If I get a pipe without a resonator, is it going to make my setup much louder?

I already have a CAI and a Y-pipe.

 

i doubt it. the one on my courtesy bpipe is a thinly shaped one. much smaller than stock. the thing that will add noise is a test pipe. it sounds hollow and more high pitched, but still dohc V6ish. my setup with a cat will be mellow, but aggressive enough to startle people when you're on the hammer. in fact, i thought the stock cat with my borla exhaust was "too quiet." lol. borla is good stuff man. you can be confident about that at least. but yes, the 2k muffler and no resonator will do just fine (quiet). bottom line; if you want stock sound stay with a stock muffler design. if you want all out performance go with a straight through design with sufficient sound absorbing material in the shell (borla).
