CPR C8 Exhaust is wrapped up

Recommended Posts

We finished up our C8 exhaust and are very excited to share it with everyone. These are hand fabricated right here in house along with every single product we produce right here in Tempe, AZ. Currently we are going through materials used and time to build so an accurate pricing model can be built along with making another to verify our fixture is dead on. But until pricing is set we hope you enjoy the video of some of the process and dyno session. I will say we did not expect the hp gains from a cat-back I truly expected 5 max considering for years now on most cars cat-backs have gained zero power. I do plan on cutting open the OEM muffler to see how it looks in there to figure out why these pickup power with a cat-back. There were no dyno tricks pulled what so ever also to note, we did try splashing in race gas at the end but the car had over 3/4 a tank of 91 already in it so it didn't bring up the octane much. But the before and after shown was truly same tank of gas 91 vs 91.
