I've got 2 1/2" dual tail pipes on mine with the big 3 1/2" tips. I've never noticed the loss of torque, but you are probably right since I did notice it on the dyno charts quite awhile back. Here's an idea that might let us prove it one way or the other: There's been some talk in another thread about converter stall speed. Since all us V8 guys have one of these, whether we wanted it or not, what if we compared stall speed RPM? The way I understand it, if you are down on torque, your stall speed would be down a bit. If you have more torque than the rest of us (V8 Toilet) wouldn't your stall speed RPM be up a bit higher? I know that if you "cam up" an automatic transmission car to where you kill the engine's low end, you can get some of the "off the line" performance back with a "high stall" converter. Also, some aftermarket companies sell a "low stall" converter for diesel pickups that put out a lot of torque down really low. Maybe we could dyno test our engine's low speed torque by using our own built in dynos (converters). It would just have to be remembered that you run some risk in doing this, such as drive train damage, and overheating your transmission fluid. When I worked in the shop, we would chock the wheels, hold the brakes, do the test really quick, and then slip it into neutral and run at high idle to cool the fluid back down. GM schools warned that you ran the risk of causing minute welds on the contact surfaces of the ring and pinion while performing a stall test with their large displacement V8s.
