Posting this here because I figured a few more guys with ITRs had Type One mufflers than the people over in the EG forum.

Anyway, I installed my Type One EG6 rear section on Sunday. I love the sound, but today the muffler is rattling out of control. To me, it sounds like something came loose inside the muffler and is rattling around. Anyone have any idea what it could be or if there is anything I could do to fix it?

 

do you have a straight pipe?. if so, thats what you get when you use one.. you can try to put a resonator in your b-pipe to make it deeper sounding..

 

Mine doesn't do that at all. Try removing the axle back and tell us what happens.

 

I have a cat, but no resonator. Does that count as a straight pipe? And it's not the loudness I'm concerned about, it's the rattling.

B2FiNiTY: So you want me to just take off the muffler and see if the exhaust still rattles? I don't know...to me it really sounds as if the noise is coming from the muffler itself.

 

No, I mean, take off your axle back and then use your hands and shake it and see if you hear anything wrong with the muffler.

 

Oh I see. Duh.

Ok I'll give that a try tomorrow.

 

You may be hitting one of the heat shields somewhere. Look for areas of very little clearance between the exhaust and the heat shields. You may be able to stretch the hangers to get more clearance.

 

The rattling you describe sounds like a heatshield. Check the one under the shift linkage first.

Either that or you have one with defective bearings.

 

LOL, if this is the case you'd better call Type One, I could have sworn the bearings had a lifetime warranty.

 

check your strap that holds the muffler in the back make sure its tight.

 

Thanks for all the suggestions guys, I'll try 'em all out tomorrow.

 

Try to replace the bolts which attach the B-pipe to the muffler or try not to use the springs.

 

I bet it's your exhaust rattling against your suspesion arms. Or do you have a rear sway bar? It might be hitting that also. Try going out of your car and bang on the muffler up down and side to side. Min was hitting but I insulated my bars with rubber hose. Hope this helps.

 

That was my first thought. My car is fairly low, and there isn't a lot of clearance for the muffler (or rather, the pipe that goes over the LCA). So I started the car and went back to move some things around and see if the muffler was in fact hitting something. It's not. The thing barely moves, and it definitely does not move enough to hit any of the suspension.
