Gutted out stock muffler?

[george graves]

I'm having some welding work done - I think the hourly rate is going to be really cheap. If it is I was thinking about having him gut out and remove some or all of the baffels.

Anyone do this? What does it sound like? Actually I'm thinking this idea might be retarded.

I did this to my 89 325is and have done this to 2 2002s in the past. What i do is remove everything inside the muffler and weld in perforated tubes going straight through and pack the muffler with fiberglass . If you keep the stock tubing sizes through the muffler it is BARELY louder than stock. On my 325 it was too quiet so i did it again with 2.5 inch perf tubes (the size of the tips) and it sounds slightly deeper than stock but chill. Shoot me a PM if you want to hear it over the phone or more details. The muffler is double skinned BTW and is a pain in the ass to weld back together.

I did this on my 325 SETA a while back, way too raspy in my opinion, It sounded like a fart cannon but not as good ( wait, did I just say that)

I vote no.

Did you just remove the internals or turn it into a straight through glass pack? Mine are not raspy at all, hardly different from stock.

Dinan has been selling their exhausts with the same design for years. only at an over priced gutted stock exhaust at $800 bucks *rolls eyes* but apparently it works

Hmm...Kinda sounds like a kazoo.
