I made this fit my 79 z28 the only thing I had to modify was the tailpipes. If you’re going to run dumps after the muffler then this is the most bang for you buck

I installed this system on a 68 Firebird 400. I do not have headers so I installed new manifold down pipes. This is not a hang and bolt system. There are measuring and cuts to be made. I had the convenience of a lift. This helped a lot. Overall this a quality system. The clamps where okay, the hangers are excellent. Be prepared for Loud! The mufflers have a great tone. Don't expect to hold a conversation while the engines running unless your talking to your car.

Definitely a quality kit. Fits perfectly on my 67 Camaro. Sounds awesome with my 355!! I was hoping to use band clamps on all the connections but was only able to do the inlets of the mufflers. Comes with everything you need. Very happy with it the purchase.

I shopped around for this and no one could beat the price I found on Amazon. As far as the product goes there was some cutting and fitting required as it is design as a universal system to fit various applications. Overall it fit well and sounds great.

This fitted and sounds great on my wife's '67 Camaro. Amazon says this will not fit the car, but it does, and it fits well. The install was easier than I thought it would be. The only thing that you have to watch for is where the exhaust exits between the body and the rear spring. I thought that it would come with exhaust collectors for headers, because it shows them in the picture, but it does not. The sound of the exhaust is what is quickly becoming the "sound of the musclecar". It is pleasant to listen to, and when you get on the accelerator, it really sounds mean. I love this exhaust, and I would recommend Flowmaster to anyone who has a classic musclecar.

I installed this kit on my '67 Camaro SS 350 and have no regrets. Tucks up nicely under the car and sounds great. Highly recommended.
