can't wait to seethe results.
I have heard that the stock side pipes cut at least 100 hp. I am still waiting to dyno my car to see once the new motor is broken in. My engine builder estimates that it should be about 650 both ways at the crank. If it was actually a little quieter, that would be a bonus. I actually feel sorry for my neighbors who other wise like the fact that I have loud cars up at my house.

Greetings:
This is great, and as an owner of an older CCX very much appreciated. I can only imagine the improvements which can be realized with a fresh look at the exhaust side of the engine breathing equation. These are on my list of improvements.

Do a back pressure test and save alot of money and time
mickmate You can save yourself alot of time and money by doing a backpressure test on each exhaust system if you are looking for just power. They have a gauge with an O2 sensor end on it. Drill tap and weld a bung to the pipe between the collector and the muffler. Go out for a test and look at the pressure reading at WOT If the is no pressure you are hurting the motor and lossing power, you are looking for 1-2.5 psi of pos+. This is where the most power will come from the motor. There are some varibles on this. Size of motor and any power adders. Anything over the 3.0 is lossing power from the exhaust system. This way is a quicker and faster way to test exhaust systems. Most exhaust systems ( sidepipes ) are toned down because of noise. Some cars need an ear plug in the L/S ear unless you like the ringing after you have been out of the car for an hour. Will someone answer the phone!! Side pipes can cost anywhere from 10-40 HP at the high rpm band. Under normal driving and up to about 4,000 rpm with a 427 cube motor stock you only loose a 10 HP. The less the back pressure the loader the pipes. Rick L.
