^^^^^^^^^^^^^^^^^^^^^^ LOL. I built an approx. 600 horse sbc vega. Sold it and put the engine in a 92 gmc shortwide. I took it to a muffler shop and had tailpipes over the axle installed, coming out behind the rear wheels much like a Camaro. I had built the 3" w/ mufflers dumping at the front of the axle previously. I ran it for about a 1000 miles before having the tailpipes put on. The second I started it to back it out of the muffler shop, I could drastically tell the diff.,it was down on power. I drove it home and pulled the tail pipes back off and reoinstalled the turn downs. The power that I was well used to, was back. I still have those 3" tail pipes in the barn, if anyone wants them , they can have them for paypal fees and shipping > 406 sbc, w/ 17/8" headers, full 3" to the axle, flowmaster mufflers. My currant 505" 68 fastback has 2" headers w/ 3 1/2" done the same way, except for the mufflers, I made my own. Take this for what it`s worth.
