i was looking at the pics on someone elses post that had a 4in mufflex y pipe. that thing is huge. does that run all the way back under the driveshaft tunnel, am i looking at the right? my next question was could it be possible to run 2.5 dual exhaust back along the driveshaft tunnel, but then i rmembered the tourqe arm? is that mufflex pipe going to get in the way of the tourqe arm? just wondering, thanks guys. lil jay

I went with Mufflex since they were designed to work with Hooker SC/LT headers and since my 383 revs to 6,500. Thats alot of gas to expend. A 4" outlet pipe will certainly help me out.

Look at:
