Would that work? It would be a fairly easy mod to make, provided you're able to weld or get someone to do it for you. It would also look completely stock from the outside. |

Internal muffler bypass that does the same as bypass pipes or the Porsche Sport Exhaust.
1" hole drilled in shell and pilot hole drilled into inlet pipe.
Inlet pipe hole widened to 7/8"
I punched through both the top and bottom of the inlet pipes and widened each to 1", so two 1" holes in each.
The cross sectional area of a 1.5" bypass pipe is 1.77".
The cross sectional area of a 1" hole is 0.79", so I have a total of 1.58" per side...very close to the 1.5" bypass pipe.
I'm going to get the shell holes closed up tomorrow and muffler reinstalled, then I'll test it out on Wednesday, so I'll report back then with results.
