I just installed Pacesetter LTs and ORP on my car and was wondering if any of you have ever added cats to at ORP for an LT1? The driver's side seems difficult and I was wondering what kind of cats you used and where you placed them? Pics would help to.

And also about the rear O2 sensors, is it possible to trick them without buying sims? Can you just put a resistor in there to trick them like you can with CAGS, or any other way? I heard someone saying this once and was wondering if any of you knew anything about this.

Thanks a lot!

 

why didnt you just buy the pipe w/ cats? ive got the same setup as you do and i dont know why you even want cats. As for the O2 sensors, you can either buy the simulators or have them tuned out of your pcm like i did.

Last i checked they don't make a catted ypipe for lt1s, you have to either have one custom made or have a ypipe/cat setup made at a shop.

He probably wants cats for something called emissions.

 

I live in MI so I don't really need to worry about emissions yet. The main reason is for the sound. I have a Loudmouth I just want to quiet it down a bit now that I have the LTs.

 

I got LM and i had a orp also so i now what ya mean. You could always switch out the resonator for a borla muffler or the new LM2 resonator from SLP. As for the cat, get one off ebay and see if you can place it in the stock position or some placethat has enough clearance.

 

Yeah, I was wondering about that new Loudmouth 2 muffler. I really like the sound of the Loudmouth with stock manifolds and am hoping to keep that tone with the LTs, or atleast as close as possible. Has anyone here tried the new LM2 yet?
