someone recently (could be on ls1tech) went from bone stock exhaust to LT, true duals and a dyno tune....picked up 43rwhp with the setup.
now granted a good amount of that was from the tune alone...but still.
some food for thought

I am alittle curious though as to how much a True Dual exhaust could be fabbed and installed for, does anyone sell a TD exhaust for our cars?

Changed to 3" true duals with x-pipe dumped at the axle and gained
''drum roll here please''
zero hp. Yep that right dual 3" pipes on a stock 346 cuin motor is total over kill and will gain no hp over a good y-pipe and catback. It sounds better but that's it.
