System INCLUDES Race Pro Mufflers!
Pricing: $680.21


How It Sounds

Race Pro


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.

Pipes and muffler are 409 stainless steel. This is the last exhaust system you will ever need for your car.

Tips are NOT included with the system. EVT49 is for 'behind the tire' exit. EVT58 for 'out the back' cars. EVT10 splitters (also requires TGF20E) for 76-81 owners.

Not quite the sound I was looking for

I was deployed to Iraq when my old man picked up this system for my '78 Z/28. I spent a lot of time debating whether or not to get a pre-made system and bolt it on or just to go to an exhaust shop and have a custom one made up with an X pipe. I really really like the performance out of this exhaust system. No drone, T-tops on or off (I have sound deadened the entire interior of the car) It's got a great sound to it, very agressive. Just not as loud as I would have hoped. The crossflow muffler fits in great (The exiting pipes out of the muffler towards the back rub a bit on the 245 tires I have so I had to heat them up and bend the hangers a bit) and keeps a nice clearance for when I decide to drop some coilovers into it.

Other than the noise I was expecting... good over all system. Well packaged for shipping.

Would buy it again

(Note... Flowmaster crossflow muffler will NOT fit with this setup)

Very Satisfied
