Chrysler hemi 265 gets a custom 3 inch stainless mandrel system

Finally the Valiant CM Hemi 265 GLX gets a long awaited exhaust upgrade after 7 years, the old system was a 2 inch exhaust with really bad pipe bends and a bit of home DIY welding to fit the massively upgraded valigrunt 265 hemi. In the end it was decided that 3 inch mandrel was the only way to go on this engine combination, and that it was possible to fit a T304 3 inch stainless system to the GLX. The new exhaust system is complete with a power pipe and performance stainless muffler to suite the 3 inch setup. the exiting pipe is just a simple turn-down instead of a straight-out, but looks totally awesome and very tough. the car now has a massively improve torque response, and is relatively quiet and cruising RPM's, but has a real hemi 6 bark under load! extremely happy with the new setup and especially the new found torque
