DIY at home Muffler Delete for $20 - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

CDBiker220 · 10-09-2009, 10:35 AM

Hey, tried something I dont think anyone's tried yet, and it worked out great. I wanted to do a muffler delete but have no money, so i just cut the muffler up and used the existing piping in it, only cost me welding wire and torch gas. Took about 5 hours of work total and less then an hour to swap catback's. Used a torch to cut the muffler away, a grinder to smooth edges and cut away excess, and a mig welder to weld up the perforated holes in the pipe, just used the existing mounts. Forgot to get pics of it finished, used rust resistant black paint to cover where all work was done, also helps hide the exhaust under the car. Works great and sounds great. I can post a video too but it sounds just like every other muffler delete, No poping, but a slight gurgling sound on decel. Definately a project though, if you have the money to have a shop just put in a pipe it would be cleaner and easier. but it was a fun and cheap project with great results

Forgot to mention this is on the LS3, the L99 mufflers are different i believe

wrek · 10-09-2009, 11:02 AM

I would fall asleep welding each hole shut! LOL Kudos.

5 hours of work ............ I think I would just save up until I could go to a muffler shop for a clean replacement pipe for $50.

CDBiker220 · 10-09-2009, 12:35 PM

I did this more for the sake of having a project, im used to fixing up older cars and doing modifications, new cars dont need any work and its boring. I feel like the car is more my own now that ive done some work too it.

CDBiker220 · 10-09-2009, 12:38 PM

Also I bought a second stock exhaust to do this because I wanted to keep my original. So Its not like I've ruined anything if i decided to change my mind. I dont think anyone has done this yet, thats why I thought it was neat, just being resourceful.

Now that is a true backyard mechanic there!

Mayhem Matt · 10-09-2009, 04:40 PM

damn looks like a lot of work I paid a $100 and it came out super clean, new pipe and new tips and I still have the stock mufflers saved if I ever have to put them back on ... good job though!

Hicompression · 10-09-2009, 06:55 PM

I'm thinking I might do the same with some slight differences. Do you think that if you used duct tape around the holes and secured it with baling wire it might hold?

I mean...that's the way MacGyver would do it.

rex113 · 10-09-2009, 07:26 PM

Not bad I wonder if you could have covered the holes with some sort of band clamp.

It's nice to see someone do all the work themselves...

It's also nice to see what the inside of the mufflers look like.

It may not look great, but sounds great and you did what you wanted & that's all that matters......

I am just glad somebody cut up the stock mufflers so we could see how they are designed inside. Maybe there is another picture out there somewhere but this is the first I have seen.

Just by looking at them, I am suprised the stock design kills so much sound. They are definently straight through, so a good design from GM on that aspect.

I don't think anyone would do that for $50. ...

-----------------------------------------------------------------
This is what someone else paid........

Ended going with the muffler delete.
Just drove the car. It sounds great. And only $170 bucks. Can't beat it.

I totally know where you are coming from. Nice job!!

VR Code R6P · 10-10-2009, 09:59 AM

I think it's a great idea you had. Was there "fiberglas packing" of some kind inside the cans, or just baffled and empty?

CDBiker220 · 10-10-2009, 12:06 PM

There was like 1/2 inch thick steel wool like packing wrapped around the holes closest to the tailpipe. Not really packing, im really surprised how much louder it got given how straight through it is. Also I didnt get any final pics, i did alot more griding and then used rust preventive black paint to paint from where the muffler started to the tip, including the mounts, so you see nothing under the car. It doesnt look as terrible as you would think.

CDBiker220 · 10-10-2009, 12:44 PM

Here is a pic under the car, looks pretty clean to me for what it is.

wrek · 10-10-2009, 06:33 PM

How loud is that without the mufflers?

CDBiker220 · 10-11-2009, 05:07 PM

Really not that loud. Its a bit loud on startup, and if you rev it its loud. At wide open throttle it is louder but not insanely loud, while cruising its barely louder than stock.

SShift · 10-11-2009, 06:20 PM

Nice to inside the mufflers. No wonder why aftermarket mufflers dont gain much.

VR Code R6P · 10-12-2009, 06:32 PM

I really like the finished pic, but would still like to see the tips left polished.
