4 into 1 or tri-y's?
Just wanted to ask the question what is a better header setup on a TPI car?
Having hooker headers shorties that go 4 into 1 collector.
Or having a custom set made and having the setup as a tri-y arrangement?

According to some dyno tests years back, the Tri-Y's out performed the 4 into 1 headers up to apx. 6,000 rpm, and when capped up (if the exhaust system is done right) can run almost as quick as uncapped.

Only maker I know of right now is ACCEL which no longer makes them. Doug Thorley doesn't have it for your setup AFAIK. LPE might have a few kits left. If so I highly recommend them. I have used them before and they are good. Coating doesn't come off. I believe it is ceremic.
