Sound is amazing, fitment not so much.
Seemingly good quality materials, welds ect. Although i have an issue where factory oem j-pipes fit like normal but the tsudo j-pipe is hard pressed against the subframe on the passenger/RH side when fully bolted up to the primary cats. The j-pipe being off center to the right and upwards also pulls the front of the exhaust piping to the right which causes the right hand tips to stick out past the bumper by almost and inch more than the left hand side. Vibration through the car is pretty bad when decelerating because of that. Otherwise this looks and sounds amazing, by far my favorite sounding system for the TL, much better sound than XLR8 and rv6 in my opinion and by far a better price. But with that price could possibly come the same issues im having but possibly not. At worst this system just needs some minor modifications to be in my opinion as good if not better than the more expensive brands. Overall i grade the materials an A for piping/welds/flanges. I give the sound an A+. The craftsmanship gets a B- because of the misalignment with the j-pipe, the value i give a very solid A as well. Vehicle: my daily driver 2006 Acura TL 6MT j32a3 w/PLM primary cat deletes and full tsudo j-pipe & cat back exhaust. Also as being my daily driver i drive 80 miles a day mostly highway at around 3-3.5kish 80-85 mph and the drone is little to none and at part throttle in the lower rpm around town its almost as quiet as stock especially with the windows up. But believe me it will scream if you make it!
