ok I posted this late Sun. night and only got a couple of responses. I have a 00 426 w/ the high comp. jug, perfect jetting, I am fixin' to pull the trigger on an exhaust, howver I have read just enough to paralyze me from making the choice. I want the most extreme pipe you can get, I have read on and on about the TA's, so thats an option, also read lots of good stuff on the Jardine Rt-4, Dr. D, FMF pbomb Ti4. PLZ HELP ME! I cannot emphasis enough, IWANT BIG TIME HIT ! Too much is never enough! And I know that the exhaust is not gonna make the bike, that's not what I am saying, what I am saying is outta the pipes out there which won is gonna give me the most, DOWN LOW WHERE YOU"RE SUPPOSED TO RIDER A THUMPER! Gosh I am rambling!
