RE: 2160 of 6400
From cats it goes into an x pipe then two 3 inch magnaflow mufflers and then 3 inch pipes to the stock tips. Its nice when cruising and loud as heck when you get on it. I love it. Almost sounds like a real 426 hemi.
The part i like about it is you can see the exhaust pipes under the back of the car, so those are polished so they look great! Also cost wise is around 800 dollars. Everything on my sys is custom bent and even custom hangers. Ill get more pics. its been raining and my car has been in the garage.
