Hi new to this site. I just picked up a RHD civic hatch with a stroked B16 and a GT35R turbo setup. The car was tuned on race gas and made 590hp to the wheels. It has a 3'' exhaust running about halfway back under the car and it turns down. It is very loud being a str. pipe like it is. My question is I am gonna get it retuned on pump gas and would like to put an exhaust on it to quiten it down but do not want to restrict it. Any suggestions on something I can do to make it quite. I cant stand the noise anymore I would rather hear the turbo spool.

 

bump im curious also? i wouldnt think it would be that lout considering its turboed?

 

Lol turn it down from 590whp to about 300 and put a real exhaust on it.

 

Skunk2 3" catback. We did a very similar set-up recently... you may lose 10-15whp with a full free flowing exhaust on it.

 

Thanks for the info. I will look into that. What about the cat since I dont have one now will I need to get a good aftermarket one or just weld a flange on for the exhaust to bolt to and run it back.

 

If you're not running a Cat now, there's no need to. A resonator will do well.
