exhaust insert

These did what i hoped. They quieted the high loud pitch down. The exhaust seams to be a bit deeper which i like and i could turn the radio down a notch when in between 1st and 4th gear in the city. They don't fit snug in the muffler there is a gap around the insert and muffler except for were the one screw comes to hold together ( wish there was two screws).

No more numb ears

Ran the hi outputs for a few months before installing these. They were a bit of a pain to install but worth it. At first I thought they weren't loud enough, but once I got used to them I love them. No more numb ears + louder than stock + still setting off car alarms in parking garage + girlfriend thinks they're too loud = PERFECTION!!
