lemme ask u guys sumthin....wat flowmaster seems   to be the best for a tracker....i was looken at the 40 series  2 chamber exaust...just tell me your opinion of which one u guys would prefer thanx

2 chamber will be loud depending on what you do for pipe. But will still be loud

It's been so long since I had mine installed, I dont know what series it is I do know that it is a 2 1/4 pipe in and out (one pipe in and out) and it's about 14" long. It's a little loud, but not to bad. I decided to get one when I saw how strong they were built. I had been through an uncountable # of factory mufflers, and tried a HUGE glass plack, and I tore all of them up. I just now tore the output pipe off of it after about 4 years of use.

i dont mind loud aslonga it doesnt sound ricey..any one thing it will?

I'm running the Calmini Header, 2 1/4" tubing and the flowmaster and it sounds good. That set up gives it a deep throaty sound instead of the rice sound. The glass pack was very rice and I was going to cut it out even if I did not break it. I dont think you will be dissapointed with the Flowmaster.
