if i put a k&n air filter and a 1 tooth upper sprocket on my 2000 trail blazer how much top speed or whatever would it add?

 

the filter might do a little help but i dont think much...and i am not shure about the new sprocket..

 

Sounds like you're in the same boat as me. WHAT MODS DO I USE. There are so many, pipes, filters, clutch kits and on and on. I haven't made any mods yet so if you find something to be successful let me know. I think I should have purchased 400 2x4. Too late for that now. The TB is a great bike just wish it was maybe lighter with a little more top-end. Beefy250
