I was hesitant to upgrade my car's exhaust system, but I'm glad I went with this one... The SOUND is deep and throaty, but not obnoxious. Automotive enthusiasts will appreciate the difference. As my tests showed, it increased horsepower and torque by a noticeable amount. The only downside is that installation can be tricky, but it's worth the extra effort for the performance boost..
Pros
Improved exhaust flow resulting in more horsepower and torque
Cons
Higher than average price compared to other mufflers on the market
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…
