First chance I've had to drive the car since switching out the quiet tone mufflers for the medium tone. Both are stainless and the system is 2". Couldn't hear much difference but really felt a big difference in performance. Better acceleration, behaves better at idle, cooler. Must have been some extra restrictions in the ones I took off. Probably just full of carbon and engine juices. They've been on there for about 4000 miles and through a lot of engine tweaking. Thank you, Don Simmons.43643

Don does good work, doesn't he?
