Yes, the 2nd chamber Im not touching. Thanks, it helps when you outline and just cut by following the lines.
If I try to replace the tube in chamber 1 I forsee issues and it wont be cost effective. Its not like in the m3 muffler where they are just 2 straight perforated tubes, you cut replace and weld.
It would pretty much looks like this. Also sorry Im not the greatest with photo shop
