What are the real hp/torque gains I can expect from a slp catted x pipe? I did a search and couldn't find anything...from what I'm hearing... about 5 rwhp[&:]???

i would guess with your setup 5-10 hp. maybe 10-15 w/ LT's too.

thanks bro...anybody else?[&:]

I would say that is if your lucky. Most exhaust mods on these cars(unless FI) don't add much power, just change the sound. To be honest, Ford made a really good flowing exhaust on these cars--single cats, 2.5" mandrel bend stainless pipes. Hard to get alot of power out of something that is designed well. Thats why older SN95s gained so much power from a mid-pipe. Some had six convertors. Even the new edges have four. My opinion---it isn't really worth the money unless you install long tubes and have to buy a new mid-pipe. O/R pipes will gain more sound, but you will lose some low end tq, but will be made back with a few extra hp higher up in the RPM range.

To be honest, my opinion is you'll gain 1-4rwhp, and approx the same tq.

Man! 1-4? I'll wait to do a full Kooks set up then... I'm definitely going FI in the future, so I'm sure they'll be worth it then.

You would be much better off doing LTs and then add a catted X. Esp if you plan on FI

jay0heavenly

yeah...that sounds a lot better.

+1...you can get headers specifically for FI as well

any catted setup you change to will not really gain you alot, deleting the cats is where the most gains will come from.
