I have these mufflers on TTI headers with TTI 3 inch "X" pipe dumped just before the rear end.
The turn downs are angled towards the outside. It is so freaking loud! But when you are sitting at the red light and give the gas peddle a little blip, heads start turning. The drone below 1200 RPM will almost make you jump out of the car and push it to the nearest muffler shop.
