I'm tired of being abused by cops about my catback, I'm planing to put the stock axelback back on the car. I have Kamikaze headers and random tech high-flo cat, is it a waste if I put the stock muffler back on?

Is it going to affect the gains from the headers and cat much?

 

Not the right place to be asking this. Look into ES oval and Magnaflow oval mufflers

 

not a fan of magnaflow. does ES make one for EM2? I've never heard of that brand

 

es oval is a nice muffler... its straight through and quiet. It looks sleeper too... wont attract a lot of cops.
