i like the sound of the flowmaster kit i see our videos on youtube of the 3.9's with that kit

 

jet stage 1 chip is this thing real or worth the $250 ????

 

jet chips are garbage, get a superchips if you want a programmer, and as long as the pipes fit with the stock pipe after the cat back, you're good. i got the whole kit, i beleive it's 2.5 inches after the cat. it works on the v6 and v8 models, and i have noticed a nice increment in torque, i hold speed on inclines a lot better than before

 

well if you could send me a link to superchips thats for my 97 3.9 id be happy lol all i see is 98
