Muffler Upgrade Help

Post by 1999Bonnie »

I own a 99 SLE and want to upgrade the muffler to get a deeper tone to it. Don't really want anything too loud but I do want some more depth to the exhaust sound. Any help would be appreciated. In fact any 99 SLE help would be nice. Cant seem to find that SLE trim when ordering any parts.

My Flowmaster 44s sound pretty good. Deep but pretty quiet.

I had a magnaflow knockoff that was awfuly loud , changed it to a dynomax super turbo and that made it much deeper and took away the rasp.
