I was wondering if anyone of you guys have heard of anybody using a 4in supra exhaust. Im planning on going for a 4in single and wanted to hear some input on my idea.
Thank You In Advance.

 

Anyone have any ideas?

 

What I've heard is that it's not needed unless you're 700whp and up.

But I'm not a supra guy, so don't take my opinion with any more than a grain of salt.

I see you're ~500whp.

Give it a shot and let us know if you get any gains, increased spool-up, etc.
