Another vote for the TTI setup.

i used their 1 7/8" headers and 2.5" X pipe system w/ dynomax mufflers on my 383. The only drilling I had to do was for the right side exhaust mount under the rear seat. I hung the whole exhaust on my back with the car on jack stands...very easy to do. I did take it to a local muffler shop so they could weld on the tips and tighten everything up. They only needed to push on one of the tailpipes a bit to line it up in the valance better. They even were very impressed with the setup.

The headers fit better than any other headers I have used. I did have issues with the #3 tube burning wires and they sent me a new left header and requested the old one back...so no issues with customer service for me.
