looking at puting longtube headers on my truck but with cats.
wanted to see if anyone gots this setup and any pics of location of cats.
thanks!

 

Dynatech LT's & cats with Y pipe. Mine is a '06 Z71, these are the only ones I have handy. They both mount up just forward of the trans crossmember.

 

man that looks good! i was looking at pacesetters but dont know how much i would have to set the cats back..

 

Thanks, I'm not sure on the Pacesetters I got all of the Dynatech stuff at the same time. Expensive as hell but it all fit, I had the AIR injection tube on the #2 primary cut off and welded over, then sent them out to Jet Hot. Satisfied with the setup so far.

 

I got the Dynatechs w/cats as well. Pics: http://s2.photobucket.com/albums/y28...jects/Exhaust/

 

here are some pics of how i did mine

 

I have StainlessWorks LT's and catted y-pipe, direct bolt in system, I'm extremely happy with them I recently gutted the cats though, but need to leave them on there for NJ visual inspection.

 

Any of you guys need to pass emissions tests with your setups? I'm kind of torn, I have to e-test every 2 years and i'm going to upgrade headers, but I figure, the stock manifolds and catted Y is probably the best thought out system for clean emissions, which is making me lean towards off-road y, and then come e-test time, just swap to factory cast iron manifolds and cats. Ideally I'd love to change them once and never worry about them again, but if places like ARH or kooks just put "high flow cats" to satisfy visual inspections then I'd be pissed to spend extra money to not pass emissions.

 

that a nice setup, thats what am looking to do to my truck.
are all long tube headers like yours on the driver side one?

 

As quoted from the post right above yours...

Our emissions is the OBDII plug in, so as long as the monitors have run and there are no codes, and the equipment is on there for the visual inspection, I'm good to go. I just passed last week, for the second time since I've installed this setup
