I have a brand new xr600r that i want to uncork and was wondering if the pro circuit t4 is a great slip on that will give me max power without being too loud. Is there another slip on that will give me better power? I am looking for something that I don't have to repack after 3 weeks of riding and that gives max power without being obnoxious. Is the yoshimura better? Any and all input would be greatly appreciated

BillG, there is no such thing as a "brand new" XR600R. Do you mean 650R my friend? I've got a complete T-4 system on mine and it's loud and it rips

Hey Deltonx,
There is such a thing as a brand new 2000 xr600r. If you read my second post I said it has 25 miles on it with the original tires. I would say that its brand new. Please read before you get a hard on. Thanks everone else with your reply's

the T4 is supposedly a very good power producer, I dont have one, but have never heard any negatives about it ... I understood how you could have a brand-new 2000 600R, but I read it real fast, anyway, hoping for the hard-on ( Im 54, and cant afford Viagra ) :applause: :banghead:

i have a T4 right now. it's too loud.
i raced and did just fine for two years with the stock exhaust and hrc tip.
i just had to have a T4 and one came along and i snatched it up.

the exhaust is just too loud. i can't wait to get rid of the thing.

don't ask to buy it either. i'm going to bury it in the desert with the rest of the dinosaurs.

I run the Supertrapp IDS2 Quiet Core, very well-built, a power gain I can feel, and one of the lower-priced pipes out there, if thats any help

Quiet = more riding areas . Loud = more complaints & less riding ares . I rather ride all day with 1 less pony than to whine there is no place to ride anymore.
