alright currently my setup is cats into a y into a spintech turned down right before the axle.

im wanting to remove the cats but im worried it will be too loud....

should i keep them and add a cut out? if so, where can i put it?

if i lose the cats how much louder is this thing going to be? maybe put a quieter muffler on at the same time?

thanks in advance.

I don't know about that muffler, but currently I have mid-length headers, no cats, y-pipe into a single dynomax super turbo (or something) muffler dumped before the axle and it's super quiet.

It shouldn't be loud. Ditch the cats.

Make it easy. Keep the cats and loose the muffler..

cats/no cats is the major determinant of volume

No drone. None. Now, with a pair of "blowmasters" and an x pipe, the drone was HORRIBLE. It's all in the muffler.

I used to have pacesetter lt's, their ory, summit 3" glasspack and a 14" mangnaflow dumped before the axle, and it got annoying after a few months. Loud and droned a lot. I just added the 4" magnaflow tailpipe p/n 15463, and its much better.

I've got longtubes, full 3" exhaust with no cats through a cutout under the cab and it still isnt loud enough for me. And thats with a loose 4k stall haha.

But I've got a magnaflow 18" oval case with turndowns when the cutout is close and i like the way it sounds alot
