it would have cost me an extra 50 bux for the triangular flange. but since my box is a 2001 and the bolts holding that whole gettup together are rusted solid. I did not want to bother. I cut the secondary cat out and slid the new pipe over the other luckily the entrance pipe to the secondary cat is 1.5in (or so) and the exit is 1.75 so the whole bypass is just 1.75 and it fits snugly over the 1.5, as far as material... idk whatever the exhaust shop had, do exhaust shops use normal or stainless? IDK. but it isnt polished and it was only 40 bones so ill let it ride. but i do need to pick up some clamps and fix some small leaks.
so in the end if you have the money to burn go ahead with the fabspeed... but if you can DIY and you dont mind DIY then this I would contend is the way to go.
