Performance, Brainstorming & Tuning Talk about modifications, or anything else associated with performance enhancements. Have a new idea for performance/reliability? Post it here. No idea is stupid! (please use Detailing and Appearance for cosmetic ideas)

I have an IMCO HF (very similar to the Flowmaster, but a little more free flow) crossflow muffler here I am looking to get rid of.
It is 2.5" inlet and dual 2.5" outlets.
I'd like to get $60 shipped in the US.
It has been used, but has probably 10,000 miles on it tops and is in very good condition.
I can post pics tomorrow if you are interested.

Ive got 3" piping (stainless) all the way to the stock mufflers (no cat/resonator)to create some kind of backpressure on my 04'GTP and sounds really good. Not to loud, not weak, just right to let others know your **** aint stock. Best run with only simple bolt-ons, 13.263 @106.72. and 13.398 @106.03, Both with 2.078 and 2.105 60ft!! Agree on that if your still in 14'*, changing mufflers are really just noise with no REAL performance advantage. I left mine on to keep my sanity when cruising. I like to hear my jams!!
