3" single shot exhaust question

[87-TURBO-T]

at what power level does the single exhaust become a restriction?

 

[novaderrik]

not sure, but i think there are guys with 3" downpipes into the 9's, so i don't thing a 3" single exhaust will ever really be a restriction for 99.999% of the general public.

The website for the new RJC 3" system says opening the dump pipe on a 10 second car didn't show any gains.

I have a 3" dp and single exhaust on my car. Took the exhaust off for some runs at the end of last year. Did not see any major gains.

Read some of this post, it should help.

I ran 9.40 with 3" down pipe and 3" ATR single shot. It didn't go any faster with open exhaust.
