Cold Start Video
OOPs forgot to add a pic since it's a pic thread. This is with the old motor in place, but the new one looks the same except for the block color
It has a set of 1 3/4" longtube headers going into 3" duals with an X pipe, Here's a couple of pics of the system as it was being fabbed. The part of the exhaust that goes over the axles are 2 1/2" tubes, we expected that to be a restriction so we had flanges added to the back of the mufflers so I can bolt on a set of tundowns for the track. The mufflers are Magnaflow's, I don't remember the # offhand but if you want it I'll dig it up, they're 3" straight through to match the main exhaust :welcome:home brew said:ZipZ28 - Listened to your cold start up. Car sounds fantastic!! :thumbup: :thumbup: What are you using for an exhaust system?
