Exhaust n/a 800
My engine made about 800 fwhp, car is for drift use, so loud is no problem - like drag cars. Must be loud

What exhaust I need too use ? (hi rev is more important then low/mid)
dual x - pipe ? what size pipes ?
dumped near axels ? (with or without x- pipe ? )
open headers ?
My headers are 1 7/8 collected to 3,5"
video of engine:
Thanks, and sorry for english!
H-pipe at 15.1" after collector or x pipe at 60.5" from end of primary tubes. This would dump right before axle at 60".
Or open headers with extension of 15" or 30" total after end of primaries
Avoid 22, 45, and 90" long pipes

dual 3" isn't to small ?
