The reason is the high performance cat converter is far superior than OEM stuff, more free flowing, and efficient. All they have to do is match the cat to our engine displacement. The second reason is the pipes around the cat converter never rust because it is the hottest point so water never accumulate to rust it out unlike the muffler.
The only thing you have to watch out is the welding process... alignment... cut old cat out... place new one in place and spot weld it to hold position... then drop the entire unit and weld it all the way around.
In the end? Far cheaper than OEM ($1335 each) or even aftermarket ($381 each). That's nut! $1335 per side???!!!!
