Default How much will those pipes hurt my performance??

Well, I need some guesses here. Had to smash those pipes a little to get them to fit.

Question is, how much will this hurt my power? We tried our best not to change the pipe diameter while doing so, but worst case scenario is Ill customize new pipes, but again this is something that will take time.

On a 1000rwhp car, how much power will those bends eat? guesses?

I really doubt that you would be able to tell the difference in horsepower. Bob

At a 1000hp, you won't see any hp change on the dyno.

36.786 hp to be excact!! The coeficiancy of drag over a hammered mild steel deviation is at a ratio of 13.76:12 or about the same as pulling this directly out of my ***! I don't think it matters kinda like my post here!!

Are those 2.5" Downpipes?

I've actually seen almost 50 rwhp on a 750 rwhp car (t3/t4) with 38mm wastegates recirculating back into 2.5" downpipes. On 3" with t4 turbos, the loss was negligible. The added turbulence (without enough volume) of recirculation is not worth it on some cars/particular setups.

Just food for thought.

Also, open wastegates sound terrible.

so you're saying you GAINED 50rwhp by recirculating the wastegates back into the exhaust?

Anyways, yes those are 2.5inch downpipes and the wastetage discharge is recircualted into the exhaust, I thought it would be better (power wise) to have open wastegates >.<
