Anyone have straight pipe/x-pipe with stock muffler?

I've been searching forums and youtube for a while to get a feel for this set up, but it seems everyone I've found with this mod has it in conjunction with an aftermarket muffler.

Anyone have it?

We've done it. Even with the stock mufflers, it's loud as hell.

However, this M3 did hit 400whp.

I tried it for a week and then added four resonators. Now it is just the way I want it.

I gutted the primary and secondary cats on the OEM x-pipe, resonators still in place, stock muffler. Definitely a lot louder now under full throttle than it was with just primaries gutted. Not really louder than stock under 3.5-4k rpm though. Smell was fine with primaries out, really smells now with both primaries and secondaries out. I like the sound though, sounds mean WOT.
