installing headers then reinstalling stock manifolds?
installing headers then reinstalling stock manifolds? Hi I'm buying a set of longtubes... I've narrowed it down to two choices:
1. Stainless steel works headers with an ORP.
2. Jet-hots with a catted Y
Questions are this if I go with number 1 with proper programming can I pass the plug in emissions test (they don't look for cats and don't do the sniffer or roller on ODBII vehicals in OR)?
If I went with number one and swapped them out with the stock manifolds every two years I need to get emissions tested would that be a CRAZY ordeal? For example I don't think it would be bad on say my 93 but have never done headers on an LS1 car?
If these answers are negative I'll go with Number 2 with the catted Y pipe...
Thanks!
Bobby

The only thing I'm worried about is the ground clearance and banging (mostly ground clearance) the Stainless tuck up into the car quite a bit which is why I was considering those I have the pro kit so Its lowered about 1.5 inches....
is your ride lowered have you had any problems???

My car is not lowered, but I do not think that I would have a problem if it was. The Y-pipe hangs down the most but that is only b/c it would be rubbing the floor if it was any closer. I liked the tight fit of the headers but if you are going to lower your car I would still get the tightest fitting that you can find.
