press-bent downpipe

[jackalopeTsi]

i want to know if a 2.5" press-bent downpipe will be able to take me to low 14's or high 13's with a fwd. i will be able to run a straight pipe(Tennessee is great, no emissions), i will be running at the track this summer, and would like to save some money if i can, i am only shooting for high 13's. i dont know how much longer im gonna have the car so i dont really want to put a lot of money in it.(spent too much already)

I ran a 13.1 with a 3" pressbent on my BIG28, awd car, full weight, pump gas.

in my gst i had pressbent full exhaust but i got it all 3" because i figured that with the pressbends i would flow about the same as a 2.5.... a couple of my buddies had 2.5" pressbent and it seemed a little more torquey ha(spelling) for low end and i had a little more top end with the 3" but for the 13's you should be fine.. i had a 12 sec goal but my car got totaled :thumbdown

Come on man how much more can it possibly cost for a mandrel bent downpipe?! I've seen them on ebay for like $120 shipped mandrel bent. Press bent CAN be done but why not just do it right?

you can pick em up on ebay for 120 shipped that all jolly but i can walkin into a exh shop on a severly tight budget and get a whole turbo back made for 120. no personally i do it right buy my gf's car is another story.

so yes i beleive 13's or even high 12's are obtainable on a press bent system.

now if you wanna be a man.. go with a drivers side exit right before the front tire.. thats the tennessee way to do it .. jk

I was thinking of a press bent 3.5 (looking for 450 whp)

You could run your stock downpipe and make that ET goal.

FYI.. on pump I ran 13.5 on a 14B, 13.1 on a 16G and 340WHP on my 50-trim (no track visits yet) with a Buschur 2.5" press-bent DP. Then again he makes them with very clean bends

Yes a 3" mandrel bent DP would be better, but your question was specific to a 2.5" PB DP.

Gonna piss off the noise Nazis. Read Dre's thread on his 3.5" and NJ noise laws.

Dre is running a bullet muffler wich do nothing to reduce sound really. Swordfish uses a 3.5 and a magnaflow, says it sounds fine.

i looked at the ones on ebay, and couldnt find one for a fwd. and most were 3" anyways. when i get my car back im gonna go with the punishment racing downpipe, and a test pipe.
thanks

I ran 12.9 on the 14b using bushur's 2.5in pressbent downpipe and a crappy custom pressbent 2.5in exhaust. It will work fine for 13's
