Exhaust Ideas I'm kicking around some exhuast ideas for my 93 Z28. I will soon be installing a set of Pacesetter LTs and I have a few decisions on how I want to finish it off:
Right now the car has factory manifolds and y-pipe, the cat was removed, there is just some pipe in it's place, and that runs back to a Flowmaster 3" Cat Back system. My first choice is to put on a Y-pipe and hope that it's long enough to reach the Flowmaster stuff.
My second choice, which is probably more expensive and time consuming is to buy a 3" X-pipe off ebay, it's only $25, and some 3" Dynomax Bullet mufflers, $40 each, and just run the pipes to the rear axle.
I'm not too fond of the Flowmaster sound and I need to get under the car and look at the cat back system itself. I figured if it was in good enough shape I could cut it up to get the piping I would need to reach back far enough to finish it.
Here's the X-pipe on ebay I was looking at:
http://cgi.ebay.com/ebaymotors/STAIN...Q5fCarQ5fParts
The dynomax mufflers are only 4" wide at their largest, I figured I could mount them right to the x-pipe. The only minor fab work would be connecting the headers to the x-pipe and then just some short straight sections after the mufflers.
Anyone done anything like this, any pictures?

You could buy a Jegs or Summit universal x-pipe kit for I want to say $75 and then have that fabbed up along with some turndowns to dump it out before the axle. That kit includes all the piping you will need and I actually run it myself, worked out really well.

I just found that searching on this site for other people's setups, that may be what I end up doing. I know the Y-pipe would be easier and cheaper but I don't think the x-pipe setup will be that much more money. On a related note, is it worth the hassle to fab up the x-pipe and dumps for a bolt on only LT1? Am I going to kill be low end torque and fuel mileage?

I wonder if the bullets would pass for "mufflers" when the drag race class requirements call for mufflers?
