Just remember the roush exhaust on earlier cars went all the way back over the rear axle and then it turned and went back over the axle and came out the side.On their earlier car they had trouble with the exhaust being to heavy and causing it to leak or drag. this is what my exhost person told me. Any way my side exhaust is a complete dual exhaust, with two MacPacs attached to it. the way it routes, it leaves the front of the engine from the factory headers to the H pipe to the catalitic converter then it goes to the side of the drive shaft and a MacPac muffler, then it has a lot of intricate curves and it goes under the gas tank and comes out to the side in front of the rear tire. It has about an half inch of clearance between the gas tank and the exhaust pipe.The exhaust is on hangers, that way I can drop it to do any work that may need to be done. My side exhaust is'nt the cervinis or any other company, Mine was custom made by David Lord of Lords Custom Performance in Bufford,Ga..
