I Have A Opportunity To Buy Longpipe Headers And Was Wondering If X Pipes Without Cats Make More Hp Than Ones With Cats. I Live In An Area That Doesn't Require Cats. Second How Hard Is It To Install The Headers?
If you are installing long headers I have read on here that it is a VERY fit in your bodystyle(but would be tight in any late model mustang). Cats don't really rob more than say 1 or 2 horsepower at higher rpms. I'm surprised you don't have to keep them on your car in Washington. I've never heard of cats not being enforced. I live in Jersey and not only is it a huge fine for getting caught not running them, but the cops could have your car towed if they want and you'd never pass inspection here either.
I got LTs out of my system when I helped a buddy do it on his 2002 Stang.
To say it's a nightmare is an understatement.
The worst part was after all that work the difference in power wasn't really that much and the sound wasn't too much different either. A little louder but the tone was pretty much the same except at WOT where it screamed more.
They were Kooks (beautiful construction) and he has a Bassani all the way back.
Maybe on a blown stang it might help, I dunno, but if I were you I would lay in a large supply of Band Aides and Beer like the others have said.
I did shorties on my car. For the amount of work I expected to gain more power. i fI could do it all over I would replace everything except header, i would run it 'till i couldn't run it anymore and then I would replace them. I would pull the motor there isn't enough space to get your hand in there. I do remember there is one bolt on the right side that is a real PITA to get to. I think by pulling the motor you could get to it more easily. Its not going to be FUN!! good luck if you do it. I would put the money somewhere else for better gains.
I noticed after I could here more engine noise and sound is nice!
