Hello to all riders. Ive been in plenty of forums for my other vehicles so I get the gist, these are always the best places to find out info I have found. A quick run down of my history, Dad was a cat man so he started me at age 5 on a kitty cat. From there it went like this, 86 Ski-Doo citation, 89 Couger 500 f/c, 89 Wildcat 650 (miss that old pig), 95 ZR 580 efi, 98 ZR 600 efi Limited Edition Black clutched, 2000 ZR 800 with a black magic 925 kit and EVERY thing else I could thow into the engine, lost that sled in a shop fire, and my current ride a 2000 Thundercat trail ported and clutched. I love the brute power of the T-Cat and I still have the 600, dependable great handling little trail sled. Cant get rid of it and the wife likes it. ANYWAY now that we are aquainted, my question for the forum, I want to change out the silencer on my T-Cat for the meaner sound, performance, and weight savings, after all we all know the big cat triples were heavy pigs. I need all the lightning up I can get. I'm keeping the stock pipes cause I dont feel like re-jetting and It really doesnt need it, she makes plenty of power, I'm pretty much throwing flowmasters on my V-8 if you know what I mean. So what should I go with, Rumble pack? mbrp? something else?
