thanks for the tips.actually this weekend i will take my rodeo to a muffler shop to get some ideas on what i could use.but if like you guys say it will mostly increase the noise i might not get it.o dont know yet.i kind of like the idea of the jet chip tunning but i am afraid that it will do some damage to my 3.2l which has the kncking and oil problem.so maybe i will investigate it little more and try out the diesel oil /rotella 15w-40/ first.not like that is gonna give me more power but might help the engine.
by the way my only real problem with the hp is not on the trail but on the hwy when going up on a hill and can not do more than 55,sometimes less.anyway thanks for the advice
