I know y-pipes will give me about 15-20 horses extra, but i want to know exactly for a y-pipe (warpspeed) or will better if anybody has any DYNO numbers... thanks!

 

15-20? Hell no. Maybe 8whp tops. Dont believe the hype about 15-20.

 

I dont think so 8hp only man...

 

Alright, prove it to me with a dyno then. I had damn near every performance item beside boosting and dynoed my 2k1 auto at 184whp. I think I got at most with all my mod 17whp. So which part of my list gave the 15-20hp?

1. Ypipe
2. Testpipe
3. 2.5" mandrel bent catback
4. UDP
5. Place Racing Intake

BTW, here is the dyno, http://www.bigdogjonx.com/fullpics/d...nobaseline.jpg

If you look in the Dyno section, that is pretty much the best for a 2k-2k1 with those mods.

What y-pipe do you have? Man i have your maxima on my screen at the computer NICE CAR!

 

I HAD the Cattman Stainless Steel one. Now my reverse Ypipe feeds a Turbo!.

I'm sorry Dog... you had...

 

You are excused. What picture you have? Hahha you have it as a desktop pic? thats a first

 

Yeap... i love your maxima

 

Dog? One guy with budget y-pipe on his maxima, he has 18hp extra and 19 torqe extra (dyno test)

 

I want to see the dyno, and im sure others will as well if he is claiming 18whp gain.

 

I'll try to find it... I think he has and stillen cone

Wierd how the second chart shows that he dynoed with the Stillen cone and everything else stock at 179whp, and then with the Ypipe added and got only 183whp. That seem like a 4whp gain at their peak.

umm, jonx, that was torque, he gained 4 ft/lbs of peak torque. and 18 peak hp. Something doesn't sound right with your number. auto i'm assuming, but still way low. what kind of numbers were you running at the track both stock and with all bolt ons? cause with those numbers, you should be around a 15.5 in the 1/4 and that just doesn't add up...

 

how much do y-pipes and b-pipes cost? and would they make much difference in a 2k3 auto? i want my car to be just noticeably loud. not so that you can hear it three blocks down. does anyone have a brand to recommend on either pipes?

 

ypipe costs about 150-350 depending on the brand and won't add much noise as long as you have stock muffler. bpipe is about the same. the noise all depends on the muffler, keep it stock and it'll stay pretty quiet.
