I was gonna replace the loudmouth resonator with the 18" dynomax to quiet up the drone. But I can get a deal on a 30" stainless works bullet muffler. I don't know of anyone running the stainlessworks piece, how does it sound? Will the dynomax quiet down the drone enough or should i go with the other bullet?

 

I replaced mine with a 12" dynomax bullet and that solved the drone issue. If remember correctly when my muffler guy held up a 18" it was really close to the driveline. I cant imagine a 30". what diameter are you looking at?

 

Thanks for the reply. The guy said it's a 3" inlet/outlet and 30" in length. If the 12" dynomax actually took care of your drone, I'd assume the 18" dynomax would help me considerably. Maybe I'll stick with the dynomax I have sitting here at home. See, I really like the sound of the loudmouth, but on long drives, the drone gets annoying. I don't really experience much rasp at all with my shorties and dual cats.

The guy says that the 30" bullet was too quiet for his taste on a lt and ory ls1. I'm not sure how that'll sound on my lt1.

 

Is there a performance difference? I have the regular dynomax waiting for install. The ultraflow looks nice.
