I am actually going with a 3" system with my new boss block build. I have the steeda catback for IRS, excellent condition, came off of my 04 Cobra. Never have rubbed them, no damage.
the catch....I had the entire catback Flat black ceramic powedercoated. Here is a pic or 2 for you. Exhaust is sitting in my front bedroom, along with the rest of my cobra as i go thru my new engine build lol! If you like the shiny look, you wont want these. If you like stealthy, these are for you. FYI....I have run them with Longtubes and an off road X, very mild at idle and cruising, excellent muffler for LTs and an offroad X. Not obnoxious at all.
