Hi, I have a 92 si and I've notice that my car is getting louder and louder these days and I'm starting to hear popping sounds too...does anyone know how much is it to replace the stock exhaust system...I'm thinking of taking this opportunity to replace my stock exhaust system with an aftermarket one but I want to keep the stock look and sound...I kno thermal r&d and brullen makes a system that is close to what I'm looking for(stainless steel is a bonus over the stock system) but from what I heard thermal is pretty loud and the prices for these systems are pretty high...does anyone kno how much it is to put them in compared to stock?? Thanks
