i have a question, what is a good pipe for a 2002 trailblazer, and does it make a difference, also were can i get used pipes?

 

Check out hpd or rcr. They will probably be the best buy.

 

A good pipe will make a huge difference in performance.It will give you a 7-8 hp gain over stock. HPD would be the first choice but they are more expensive. You can get a whole Speed kit from RCR for the same price of just a pipe through HPD. Stay away from DG pipes. You WILL lose hp with these pipes. Dont let the price of the DG pipe temp you because it will only cost you more in the long run if you buy from DG. Here are some web sights to loo at.

Hot Seat is not known to have the best motor parts for Polaris's, but they are the ones for suspension mods. I have not had a good experience with Hot Seat, so these are just my opinions.
