When considering aluminum coated pipe, keep in mind diesel exhaust is oil based which will make the pipes last longer. In that case, Farmboys makes a great kit and I have a tip I will sell for $50, 4" in and 5" out chrome, still in original plastic
good luck!

Not too many of your local muffler shops have the ability to do mandrel bends and I wouldn't have a system with compression bends in it. Perhaps you don't understand the significance of the difference.
The duals will not give you any additional power but they look good and I think they sound better. I just did a full 4" on mine using a 4"downpipe and cat delete from RPM Outlet and a Magnaflow dual setup all in 409 SS. I didn't like the U clamps in the Magnaflow kit and replace all except the two on the Y pipe with the hangers with 4" SS band clamps. They do a much better job of sealing the exhaust and don't crush the pipes. The 1st section of the downpipe that hooks to the turbo was about 2.5" to 3" too long. The second stage would not line up correctly. I had to take it back off and trim 3" out of it. Other than those few tweaks it wasn't bad. I still have a vibration from the downpipe rattling on the pinch weld on the firewall. I will take care of that this weekend.
