[QUOTE="EddieS'04, post: 982650, member: 61136"] Free flowing exhast will loose low end torque, only if your pipes are too large. Not gain. You will gain wot HP with free flow. I think the only company making a complete kit is Gibson. If you have someone build from cat back you can go up to 2 1/2" pipe. With HP gain and no torque loss. with a baffle type performance muffler. The y-pipe Hugh refered to is only available for the '01 to '05 trac, gen1. IMO For cost savings and about as good as the gen2 4.0L, will get. You can stay with the OEM 2 1/4" pipes. Cut the oem resonator and muffler out. Then weld in a magnaflow muffler. It is a SS straight thru design. Shop around, $60 to $80. Will be good with the OEM 2 1/4" pipe. Weld a nice SS tip on the end. You will maintain good low end torque and gain HP. Might cost $40 for a shop to patch it in. A complete factory cat back, $250 and more. [/QUOTE]
