Ok I found a Dual side exit exhaust at Mac Performance.

I was just wondering if anyone has used it yet and what their thoughts are. I have Mac Exhaust on my mustang and I love it except for the headers. But even they aren't bad. Mac stuff sounds really good.

 

If you just want the sound and don't care about quality get a mac system.

 

the only problem that I have had with my Mac stuff on my car is that the headers are hard to put on after your have run then and taken them off. They really need to have a single flange. of course it is aluminized and not stainless but my pro-chamber and mufflers have held up well. Also their mufflers have been proven performers on mustangs for a while now on the power side.

 

I read a great review on MAC exhaust the other day. Can't remember which magazine it was in though. It claimed 25 hp gain with the headers and cat back...Kevin
