why ory
its the y-pipe that comes off of the headers. the stock one is flat on both sides and very restrictive in air flow. ory= off road y-pipe. if you have long tube headers your stock ory won't work as its too long for the headers. won't match up.
I Guess I Have One That Is Custom Made Because I Bought The Car About A Year Ago And It Had The Headers On Already And There Is No Flanges It Welds Right From The Headers To 3 Inch Piping And Goes Through The Cut Out And Out To The Back Of The Car.

Just to set the rumor straight: The stock y-piping does NOT pose a significant restriction, regardless of the pancake shape! The cats pose a minimal restriction on a stock car, and more so on a modded one. The pancake pipe is ugly, but NOT restrictive. This is tested and proven.

Do a search for before and after dyno's of the SLP replacement pipe. This pipe replaces the pancake section of pipe, and is a very nice piece. Most have dyno'd 0-2rwhp, and some have even shown (-)numbers. Do a search and check it out. This makes sense also, because there is nothing restrictive about that piece of pipe. The pancake shape is not a big deal, and the diameter is still as large as a round piece of pipe.
