Long tubes will out flow and produce more power over shorties any day. Shorties will make a litle more power over the stock manifold and would keep the cats almost in the stock postion if you needed emmissions. Some times putting a catted Y pipe in with LT headers can still give the 02's a differant reading because they are further down the system.

well i need to pass emissions and need cats so what would you suggest? i have a loudmouth catback with high flow y and cats now but the stock manifolds...i want a little more power and better sound while still passing emissions without spending crazy money...would throwing some shorties on there accomplish that?

yeah but then we're talkin at least $300 for the headers assuming i go with pacesetter, another couple hundred for the ory and about $300 if not more for the cats...i'd really like to stay under ther $500 range...this car is my daily driver, maybe a day at the track here and there but not an all out race car by any means

You can get cats off of summit or jegs for 60-80 bucks. Thats about as cheap as its gonna get...Please dont waste your time w/ shorties.

Yea thats if you can get some gutted cats for free or laying around. Im telling ya man ive been doing this alot of years, and I always try to find the most cost effective way...Its not getting any cheper then what I listed except for picking up used. Thats the route I would have done but I bought my car w/ Catted headers.

mid length headers do not bolt up to the stock ypipe.
so you still technically move the cats...which is technically ILLEGAL.
for your emissions test...is it a sniff test only? sniff and visual? or visual only?
and if its visual...do they just glance under to see if they are there?
depending on your state/local requirments....you could go any one of a dozen routes.

i dont know about you guys but on my car there is only one cat that is visible anyway...on the passenger side, the driver side one is tucked way up there...
, Plus my car was tested as a ODB1 even though it has a Ls1...yes still have the mids, which like posted about is still "illegal" because of the cat movement.

A lot of guys will swap back the stock parts for the test, then re-install the headers afterward. It's a bit of a hassle, but it goes quickly once you've had practice. That's just the price you pay for enjoying this hobby.
I once had my own plans to take the smog legal high road, but once I did some research and realized how limiting the stock exhaust is, I changed plans.
