muffler opinions

[454muscle]

I have the same problem. Flowmaster Super 40s with 3" exhaust and it's far too loud, even with cats.
I got me a set of these "silencers":

I haven't tried them out yet, but I will find out in spring. I wonder how they will affect sound/performance etc. They will be easy to insert and remove because they will fit in the 4" section behind my tips.

IIRC, their site should have sound clip/videos of different mufflers, pipe diameters, engine combos, etc.

And they also have a youtube channel with LOTS of sound clip videos.
