I know this has been talked about before. Does gutting apex exhaust make the sled loose hp. Should you cut everything out or just drill holes in the baffles.
At first i cut the baffles out but it was 2 loud 4 me, so I reinstalled them and drilled a 1/2" hole thru both. It's a little louder but not 2 loud. It does nothing 4 hp.
