How It Sounds

Race Pro



Same as SGF70 but the X pipe, Muffler and tailpipes are polished 304 stainless. Clamps and hangers are also stainless to complete the ultimate exhaust system.

This is the first system on the market with a true 'straight thru' flow path. That means that even though there is one muffler there is two completely separate flow paths for each side of the exhaust. There is absolutely no loss of flow thru the muffler. All other systems include a flow path that create turbulence and restricted flow in the muffler. This header back system includes a driveshaft tunnel X crossover kit for maximum ground clearance even on lowered vehicles. Manifold downpipes are available as an option for those that do not have headers. Great for even the highest performance(up to 600hp) applications where ground clearance and oem 'look' is a priority.

Tips are NOT included with the system. EVT49 for 'behind the tire' exit. EVT58 for 'out the back' cars and EVT10 splitters (also requires TGF20E)

I installed this system on my vehicle about 6 years ago, I've brought it to many car shows and everyone is always impressed in the "rumble" the exhaust system has. It is not too loud or in any way obnoxious but yet lets you know the American V8 engine has some serious horse power under the hood and it sounds perfect. I've listened to many other 78 Trans Am's with Magna Flow and Borla systems, none sound as good as my Pipes system, not even close. They nailed it !
