I agree with 808muscle... talk with some friends that have hot rods that aren't street legal and ask where they get theirs..

Find out EVERYTHING that any visual check will look for. As an example, in CA and some other places, LT's will fail the visual, just like having no cats will.

Be prepared to show any CARB or EO stickers or similar documentation for any of those aftermarket engine parts.

In Oregon the do the OBDII check as well. No visual inspection. I have the stock Saleen magnaflow exhaust, with CATS, running a 302 stroker (well 4.6 stroked to 302) and I pass just fine. First few times I went I failed, and then came to find out that despite mentioning I have to go through inspection, Brenspeed turned my rear O2's off in their tune. They wanted like 20 or 30 to turn them back on, but reminded them of my original request and they sent me a new tune free of charge.

If your rear o2's are off, you will NOT pass a proper OBDII check.

With a proper tune and cats, don't see why you'd still throw codes.

Alright just got off the phone with Jim at JDM and he said my best bet is to just throw the stock system back on. He said yes they have tuned cars with high flow metallic cats, but they 99% of the time turn off the rear 02's on a car with LT's. He said with more and more states getting stricter with emisisons he suggests to just put the stock exhaust back. He said sure we can try and tune with the rear 02's on, but if your throwing codes your than going to have to deal with removing the headers and getting a tune. This car is my DD and I am 18 so I really dont have the time, nor another car, so I am just going to put the stock system back and maybe buy the Ford Racing throttle body to pick up a few hp I lost from removing the LT's.

buy a cheap *** xpipe that will fit your long tubes and just cut the stock cats off and weld them onto the cheap X and you should pas no problem..I dont know if you wanna spend like 130bucks for a new X just to cut up and use once a year.
Thats one thing I like having mine as a toy..under 5k miles a year so i dont get any emission testing done..I get an exempt sticker and dont have to worry about my rear o2 off

You need to call someone else. You are about to waste a lot of time to remove a system that is perfectly capable of passing your emissions.

OBDII scan is only checking to see if you are throwing codes. Use O2 anti foulers and you won't throw any codes. You could even have your stock cats welded up to fit your current exhaust. I bought high flow cats and had them welded up so they are easily removable. The day after I passed I put the straight pipes back in. I had the same Pypes LT you've got.

As for the tune, Brenspeed did my tuning. The ONLY THING they did for me was give me a new tune with the rear O2's turned back on. That was the only change and I passed with freaking cams.
