Hi all,

Has anyone removed the filters from the muffler box? Is this akin to having a non-resonated exhaust?

Does it cause more free flow?

Any pros and cons to this modification?

Thanks

EDIT: What car are you talking about? I was thinking s40 v50 below...

When you say muffler box, do you mean the rear muffler with the single input and exits on either side that go to either exhaust tip? Or do you mean the resonator that is after the downpipe?

I think modding the OEM exhaust is just setting yourself up for disappointing results. Get an OBX system or some aftermarket muffler if you want better sound/performance

Just cut the OEM one out and have a free flowing one welded in place.

here's a cell phone vid of my setup:

it's got an OBX straight 3" DP with a 2.5" converter to a TME muffler. No resonator. There is another thread on here where somebody else took their resonator off of the stock exhaust and it didn't really do much.

Damnit that sounds good, need to hack out my resonator at the very least, go from there.
