i love my stock exhaust on pepto.
the boso tip added aa nice sound but its stock exhaust all the way back.
and when you start to learn how to slide your gonna be street sliding, and loud exhaust brings unnecessary attention. the tires are loud enough as it is.
so just lay low and take all the positive advice you can and try to learn as much as possible. good luck on finding a nice car,
i know zolika is the man to go for for s14's he sells them in mint condition and for a really good price. he does great work.
