...has me thinking..... I wonder if I get them set up coming out where yours are but exiting back into the exhaust post muffler. Basically just a muffler bypass. ...could be a clean set up if there is room...

Not sure if there is enough room to enter the tips after muffler, or just
extend tip pipe to allow ???

That is basically what I did with mine Michael. I just cut a by pass in the side of the muffler to avoid the baffles. But I think it could be done externally as well by T-ing off the input to the muffler and Y-ing it into the pipes after the muffler. The problem with that is when I tried it you only get about 30% relief and most of the exhaust still goes though the muffler. It wakes up at WOT but not like full blown cut outs.

The easy way to get it all is to pass straight though the muffler. If you look inside your muffler where the pipes enter it there is an open chamber there. The stainless is darker on the back side of that open part because the input gasses pass straight though and hit that the back wall of the muffler there. So you just put 2 pipes straight back from the input pipes with cut outs in them you'd have it. You could make it pretty by doing a center mount exhaust off them or dump them into your tail pipes.

I follow what you are saying, but it wouldn't fit the aesthetics I'm looking for. Honestly if it only made a 30% increase I'd likely be damn happy as it it'd be bearable to drive around like that then close them in residential areas or with the wife on board.
