We are looking as you know into a test pipe for our cars, but hearing some feed back we are looking into cat back exhaust instead. If you own an Si or know someone that does that has exhaust what kind is it? And does it cover up the sound of the bad *** b16 engine? Any input would be helpful.

 

They are not cheap, from my work it still costs over $400.00.
I am learning little by little about cars. My B/F has been teaching me.

 

I know that there are searches I can do, but I enjoy hearing what other people who are interested in what I am like. I thought that would be appropriate in the "tech" forum.?! I do have a header, but it is kind of foolish to leave it open there and then restricted at the exhaust part.
