I have aquired a flowmaster 3in mandrel down pipe and the x over pipe. Any idea on what the gains will be?? It already has a 4in exh from the down pipe back. Im thinkin with all that has been done to it that it could maybe do some good. The down pipe i have in there now is a GM one i bought new and it's pretty decent.

Just a note: JK's big chip, the intercooler and the oil cooler mod i did have made this pretty stout, for a 6.5 it will walk the dog. Thanks to all who have helped me make this 6.5 somthing decent and worthwile.

I think the downpipe is the most restrictive part of the exhaust. I think you'll see a differnce. I never noticed anything when I replaced my crossover except a little faster turbo spool-up. My rig has all JK exhaust with ceramic crossover.
