Need your help on 383 Dart exhaust

i took a customers car to my muffler shop with the x pipe and extensions he got from jegs, and it was so thin that when they went to work with it, it split. all i was saying was that their pipes are thinner wall than what you get at a good reputable shop.

The JEGS kit is 16 gauge pipe (1.5mm) same gauge as what you get from most muffler shops that bend pipe and thicker than parts store replacement parts. Plus the pipe is manderal bent which you won't get from the vast majority of muffler shops. You will pay over double to have shop bend you up something and triple or more if it's manderal bent tubing.

The question regarding the JEGS and Summit kits is a pretty common on mopar forums and everyone that has had them with the exception of redfastback have good things to say about them. The reason they are so much cheaper is they are bent on computerized equipment in volume keeping the labor cost to a minimum.

I have a compression bent system on my car from a local muffler shop. It's on my to do list to cut it out and replace with either a JEGS or Summit kit because they didn't put enough hump in the pipes over the axle and the shocks hit on full compression of the rear suspension. Plus some of the bends reduce the pipe diameter almost 50%. At the time it was the most expedient thing for me to do plus it was a relatives shop and I only had to pay for the mufflers.

Whoolph, I wouldn't hesitate to go with the JEGs kit in 2.5", you don't need 3" until you start making more than 500 HP and in your application the only thing it will do is make more noise. If you are getting down pipes from the manifolds wait to you get the exhaust installed, you may not need to do anything to mate up. A quick and easy way to get you up and running until you decide on whether you want to go for headers or not if the pipe doesn't line up is to pick up at the local parts store a couple sections of corrugated flex pipe, that will allow you to mate up the pipes. If you are handy with hand tools there is no reason that you should be able to install the system in a leisurely Saturday.

H and X pipes will primarily cut down on the noise level of the exhaust system. If they are placed properly in the system they can add power but its much more effective as a power adder with headers. The H-pipe is going to be much easier to install.
