Question on FLP Header package
I keep looking at the parts list and need to know what the "off road pipes" are for considering the kit comes with:
1 3/4 inch long tube headers with a true 3 inch collector (ceramic coated inside and out)
2 off-road pipes (ceramic coated inside and out)
X-pipe with flanges for connection to stock or aftermarket exhaust (ceramic coated inside and out)
2 high flow catalytic converters
All bolts and gaskets
4 v-flange clamps
2 band clamps
Do they replace the cats?
Getting ready to pull the trigger on these puppies.
Thanks as usual.

Below is a picture, first with the cats in place just behind the collectors, and then with the off road pipes in place of the cats. ORP's are just straight pipes - in other words, running catless.

So they give you the necessary parts to go CATLESS cool. But I'm a CAT kind of guy.
Did you get "tuned" after installing your headers? How did your car respond?
I was running real rich the last time I dyno'd will that help or hurt with headers?

Re: Question on FLP Header package (AFVETTE)
Yeah, you can go catless for some aggressive sound and a few more ponies. I didn't get tuned until after I did heads/cam/gears recently so I drove for several months with not adjustments after putting in the headers. It smelled rich at idle.
When I went in for tuning, they told me I was running quite lean at part and full throttle even though it smelled rich at idle. With the extra breathing, hopefully it'll help your AF though there's no substitute for tuning.

:iagree: with Patches. Had the same experience after installing my FLP's. On my Head and Cam car the straight pipes yielded 10RWHP and 8RWT on the dyno.

AFVETTE:
Put my order in for a set today at the special price of 1439.10. That's a great deal considering everything you get with the FLP's. I'm going to tune for and run with the hi-flow cats on. May go to the straight pipes once and a while if I can borrow someone's lift. Best of both worlds.
