Is a cobra utlity/quiet pipe any count, Seams to be a reasonal price at 119.95. It is for a 300 trx 2wd. What are some good pipes to put on without having to put bigger jets on?

 

Any pipe you put on will require new jetting. You are changing the air flow- generally increasing it- therefore you need to increase your jet size to compensate for the extra air... or you'll be running lean.

I reccomend the White Bro's E series slip on- I gives you a nice boost in power and sounds bad as hell!
