Exhaust help for SC track car
Tried posting in RC and didnt get the answer I needed so maybe ya'll can help
I finally got an engine for my caged CR project. its going in next week and I need some exhaust help. Im planning to make about 425-450 wheel on the SC kit for a track only car.
As for exhaust I was thinking berk header back:
Fair price with test pipe. But after some research Im seeing 3in is not the best for SC. Better to stick with 60-63mm size. That leaves in single greddy revolution and BC spec II. or any other others? need to stay under 600
Any help would be appreciated.

Because you have an exhaust cost limit I would say leave it stock as well. I have a custom LHT performance 70mm dual exhaust now which isn't bad at all but I always look at my stock exhaust sitting in my garage, battling if I want to put it back on.

After some more research last night I think the issue that is causing the smaller exhaust to dyno higher is the cam overlap on the stock setting. So choking the exhaust would allow manifold pressure to rise and prevent leaking thus increasing boost and HP. But its robbing Peter to pay Paul IMHO. So maybe the best solution is a larger exhaust with cam gears to space out the overlap a bit solving the manifold PSI loss problem and having a more efficient flowing exhaust.
Just my thoughts after some reading... Could be wrong...

I was in a similar situation as you, but came to conclusion to the tanabe medallion touring and ct exhaust. Local guy was selling a ct exhaust for 600 so i bit the bullet on that one. Doesnt feel as flowy as a 70mm greddy single, but most definitely quieter. Sc tuners say stock or 63mm exhaust works best with sc. Not a believer yet until i get another dyno in

true indeed, only reason I haven't gone back to the stock exhaust is that ilovemyhonda made awesome numbers with larger diameter exhaust partnered with a larger blower of course
