Muffler mod / gutted cats HD audio



Made this today in case anyone was wondering what the sound might be like by hacking up a $2000 OEM exhaust. Cost me roughly $85 since I used exhaust heat wrap inside the muffler instead of replacing the pipes with solid ones. Couldn't be happier.

Sound's exactly the same as mine...i replaced the 2 big perforated pipes by 2 full stainless steel pipes
But i think...on long term...your exhaust wrap(the easy solution)will burn away,due to the high temperatures inside the muffler !

It probably will but working at a body shop is a perk. I'll just do the replacement later. I wanted to see if this would be enough for my liking or if I should fork out the cash for aftermarket. Aftermarket will net power gains on the muffler side, and I doubt this nets much of anything. The cats though did help. I notice a change in torque.

It's not straight through since it has the primary cats still and there are no CEL issues.

Cool stuff! I am doing the mod as well but getting rid of the middle part of the muffler all together and replacing the 400 cells with test pipes. I am excited after hearing that HD clip. Thanks for the share!

So this is with the 200 cells gutted?
