problems with longtubes?
if you live in a non smog zone, no checks, if you put on a set of longtubes, with the EGR and all still on the, what type of codes will you get, and problems will you encounter? Can you still keep the cats?

I had a dyno tune done when I installed the long tubes with the hi flow cats.
One of the benefits of doing the dyno tune is so they can take care of any codes/problems.
I have not had any issues after installation.

Yes, you can still keep your cats (go with hi-flow aftermarket cats)
You might need to have a tuner disable your rear O2's. Some of us get codes because the rear O2's are further back. O2 Sims will also work. I *think* most, if not all systems now have provisions for rear O2's.
To get the real benefit of headers, you really should get the car dyno tuned.
Other than that, a properly installed header/x-pipe/cat system will give you years of trouble-free use.
You won't regret it.

I do plan to have a dyno tune after having 1.8 rockers and 918 springs installed.
So do you think a dyno tune is the way to go to get the HP out of the LTs instead of a street tune?

So how bad would a set of lts and a x pipe hurt my clearance? Also, if you get rid of the cats would it show any more codes? If it has same amount of codes with as without I'd rather get em out

i didnt think you'd get a code if the rear o2 sensors have been disabled?
