Hardware absolutely sucks.

These are great pipes. Good quality and they git nice. The only reason they got a 3 star is the ridiculously short t bolt they manufacture to mount the pipe. When everything is in the frame and together you have. 00000000995 mm to get a washer, lock washer and bolt. There is legitimately no freaking reason the T bolt can't be a 1/4 or 1/2 inch longer and all of your problems would be solved. Expect to run to a parts store for longer T bolts.

Are these baffeled

Is there a technical specification sheet on these? I'd like to use them for a different application. Such as length, and other ways to connect them to the engine? Are they slip on, so I could have a shop bend a pipe to this pipe? Inlet size?
