Summit turbo mufflers.Nice mild rumble at Idle.Quite at speeds.Good power. Had them on my car for 9 years now and sounds the same as when they were installed.Good price too.More costly, but Dynamax sound mild too.My engine is mostly stock. No big kaboomer cam.Have used the Summits from 225's to 472 Hemi's. I like them. Just a thought.
