I have a brand new heffner exhaust (on car for very brief time) for sale. I put it on the car but decided I liked the original exhaust tips more. If anyone is interested let me know. Rick 508-397-6815. I has the heat shied attached.
It was a little louder than stock at idle. At WOT it was considerably louder. Really nice piece of kit but I just like the original exhaust tips. It's interesting that the wife and kids liked the Heffner more.
