2'' was the winner. I got 2" and its all good, of course once my turbo is on, I will have to up a size.

i read on here if u go bigger then 2 inch piping from the cat back the back pressure will be to low...

stop right there. backpressure is your mortal enemy. replace backpressure by exhaust gases velocity and you're right. One day I'll get pissed and post the difference. for now, google for the difference. I'm not trying to be an ass, it's a common mistake I hear almost everyday.

Thank you for saving me from typing.

Oh and horrible stock bends? Have you looked under the car? The stock bends while not mandrel are actually quite good

i thought i saw a post where someone said that the bend angles towards the back are bad

[ontarian_frog]

Any bend that is more than 45 degrees ish will be bad, no matter what the bend type (crushed, mandrel...) We have two 90s then followed by a 30 in the back, plus the stock choker (muffler). BUT, the stock piping is still pretty good. It's actually the stock muffler and cat that are the bad on our cars.

you can always go with my version of the hi-flo cat. unbolt flexpipe from cat, unbolt manifold from block. lift out of engine bay. unbolt cat from manifold. find a hammer and screwdriver thats longer than the cat. place screwdriver in cat and smash the ceramic insides of the cat out. clean up mess on the floor. clean up manifold a bit. bolt everything back together in reverse order.

*note: exhaust will have metallic ringing note.

**note: exhaust will smell rich

***note: only do if your a ghetto bastard like me and like to mess with ****

****note: CEL may come on, do not worry as its just the second O2(not the importan O2 sensor) reading below threshhold
