Review on Dynomax 17742 Spr Trb Muffl 6 by Michael Eldridge

Installation was easy, but you definitely need a welder. I didn't, and one day he fell on the street. Got it back for now. Also make sure you have a straight enough length of old pipe to attach to. Part of my problem is that the pipe bends so close to the muffler that you can't mount it very well. I don't think Ford intended to use aftermarket mufflers. It definitely adds a bit more power and improves efficiency! I also like the deeper note of the exhaust. I believe this model flows at 275 cfm and my stock muffler produced less than 150 cfm. The car is a 1991 Ford Tempo GL. Though Revain says it won't fit, it will work for Tempo. It's just not the same as the original and you'll need a new exhaust and suspension. Highly recommended! Also comes with a Dynomax decal. It's under the hood next to my K&N sticker. XD
