01 longtubes mn6 question
--------------------------------------------------------------------------------
I posted this in the general forum as well.
Hopefully with a little cooperation from mother nature next week my car is going to East Coast Supercharching for headers - hi flow cats and x-pipe, plus a rear gear change. My question is will the longtube headers and hi flow cats ommit the need for pup cats? My understanding is that they were only needed for 00 and 01 until they came out with a new material used in later cats that didnt need pre heating. So I'm hoping to eliminate them with no ill effects to emissions! Any help would be appreciated

Since ECS is doing this work for you, I would also recommend you get a tune in order to maximize the bennies from your new exhaust. A good tune will address matters like this easily.

Yes Pup cats go with LG longtubes no question about it!
You see or smell no difference as long as your installing HI Flow Cats with the hearders.
I have this exact set up and was glad I did the install.
