so heres the deal. my car in obd2, my turbo is pushing 8-9psi. is getting a hi-flow cat worth it, or should i just get a simulator or gut it and convert to obd1. if i go with the seconed option im worried about being loud and dirt bikeish. anyone with a TURBO and no cat(gutted) could tell me how ur car sounds would be great!!!!!(SORRY I NOTICED I WAS IN THE WRONG CAR TYPE)

Just convert to obd1 and lose the cat. You will notice a big gain in hp and it won't be that loud either.

you can gain around 20 whp from just removing the cat in high hp motors
