What can I do next to mod my car?! This Secondary Air Injection is really starting to get to me...
I've got the GMPP exhaust, and intake with a bit of modifications to bypass SAI problems. What else can I do? I can't get the GMPP exhaust manifold. What about the downpipe? Does SAI affect this as well?

This is my first car. And I was hoping it would be something to be proud of when modifying...except I can't really mod much!
Sorry, felt the need to rant...

 

i used to have an 06 lt, i had the pacesetter exhaust...i hated the SAI, i always delt with my CEL lite.....theres not much you can really d about it because there is no exhaust manifold made for 2.2's with california emissions. unless you can custom make a working seat on the exhaust manifold for the valve. besides that i just sucked it up. but now i have an ss.

hopefully hp tuners will get something out t help out with that, i emailed them when i had my 2.2 (had it till last september) and they said not expect anything till 2007.

 

Anyone else have any ideas on what else I can do?

I suppose I could hold off on the performance for now, and start working on upgrading my audio & finding a body kit & some wheels...

 

Haha. I'm in the same boat. I looking for a kit and rims now and waiting til someone gets their **** together to make us one.

 

or you can just go and buy a 2.4L engine and swap it...

 

Whoa....I'm nowhere near that close to knowing about cars.

 

well i figure if you have enough to just go out and buy and 2.4 engine you have enough to get it installed or to just go buy an ss... I mean the engine would be arounf 5k and 5k added to the 13 or 14 you paid for an LT you would have had enough for an SS

 

why would anyone even think about doing that putting the 2.4 engine into their 2.2?? spending a total of at least 7-10,000 to gain about 26 horses? don't think so...

 

well you can blame the liberals for ur sai issue....

 

bro, i have SAI as well.. you can go ahead and put on the downpipe, i jsut installed mine like 2 weeks ago.. only thing it affects is the header i love the CA downpipe.. made my cound sound nicer..only thing is it isnt GMPP so u might lose the warrenty for the exaust

 

Wait a minute....what did you do? Details please.

 

look at his car domain

 

Which one of the XTC downpipes did you buy? The one w/ the HIGHFLOW CAT I guess..?
Are these meant only for the 2.2s?

 

ok so i was kidding about the 2.4... and what good does a down pipe do? (not being a smart ass... i really don't know)

 

You guys correct me if I'm wrong...
I think a better downpipe will promote better airflow to your exhaust.
More airflow = More horsepower
The stock downpipe is a bit restrictive. The idea is to create the best airflow possible for your engine.

 

Yes I read up on downpipes, the tubing is wider thus allowing more airflow to pass through, because it is less restrictive. More flow means more "potential" power. I say potential, because if you have no way of getting more air in, as in forced indution, then you have no way of getting more air out. A CAI would be a good start to allowing more air, ad cooler air at that, but it still only allows so much flow. A downpipe would be most efficiant with a turbo or a supercharger.
