i have read all the posts on the es oval and magnaflow and i have come to a conclusion that they are both the same. but some peoples are loud and some are not. how can i acheive the quiet es oval muffler w/ custom piping? i have a 92 civic with a b-series motor and i would like to know what size piping, muffler,
b-pipe(dont know what that is) and cat(do i gut the cat out or get a pipe made? oh yeah.. and resonator?

 

some people run long resonators and some don't.

 

resonator will quite it down, as will the stock cat, but they are both straight through mufflers, so its not going to be quite, just less loud
