Performance Downpipe Wanted
You can see the mods I have below.
It did not occur to me that the downpipe would be a problem. I guess I was just happy to have the new parts. What downpipe should I use to replace the stock pipe? Where do I get it? I tried to research it , but found no pipes that say they work with GMPP. All input welcome..... BTW, I saw a thread where someone wanted to buy a stock 2.2 downpipe. I will have one sitting around soon. (Hopefully)

zzperformance.com, cobalt-addiction.com, make one yourself lol. its easier to just buy one, but im the kinda guy who wants to do it all myself. im sure there are other places, thats just off the top of my head.
reason i say you should get a new downpipe is because you have a better flowing catback and header, but the stock catalytic converter is incredibly restrictive. to benefit from all the mods, that should be replace or removed. becareful if you decide to remove it, a lot of people tend to dislike the sound. -----Added 7 Oct 2008 at 06:14:10----- how indepth are you looking to mod your car?

That depends.
I was looking to add the 2.4 I/T Manifold and a jet chip. After that I am not sure. I am open for suggestions! Also, my LT is a sedan.... But, the kids want to go fast too! LOL

oh you could get into headwork. port match your header to the head, port match the intake side as well. new valve springs, and get a trifecta tune, although im not too informed on it. i suggest getting prothane mounts as well, cheap. what they are is replacements for your tranny mount inserts which help get the power to the ground. ride quality may suffer some, but most who use them dont complain. the list can go on and on

I saw a post about the mounts.
It had to do with wheel skip or something. I believe I will go as far as the bolt-ons will take me. We'll see how much the "fever" is then. As I said, I am just looking to smoke a few people on the way to work and back!

That would be fine except I already bought the GMPP manifold.
