So Deb, There is now a CGS available for the 2.2? One that doesn't require grinding something down, or cutting something off to make it fit?

 

The T-924 arrived yesterday and I guess I'll have it put on the Altima Tuesday. After I let her hear what it sounds like, (And she doesn't point and laugh! ) Maybe I can twist her arm enough to go for one on the HHR too! Maybe I can stretch the truth a bit and say she'll get 5 or 6 more miles to the gallon. Once it's on, it's on!!

 

all you have to do is
mark the bar where the bend is on the bottom of the bend.
straighten the bar flat
bend the bar the same way it was before 2 inches closer to the tube
drill a new hole to the appropiate spot
you remove the back left bolt from the top of the intake (where the new bolt goes)
get a longer bolt and it needs to be 2 inches or 50 mm long
bolt it to the back left where u took it out

that is all the necessary changes to make to make it fit.

 

Well, got my I924 installed today. Not a bad mod really. 35 bucks for the Imco, and only 40 for install. Sounds incredible. Even though it was hot around here today (92) I couldn't help but ride around with the windows down just listening. Hell, I've still got the stock intake and it surprised the crap out of me when I chirped the tires after getting the green at the light by my house. Can't wait for the CGS to get here now. Was lucky and got one of them thar ceramic coated ones.

 

Well, my plans got shot down this Morning! I took my Altima to two different muffler shops and got the same story. Seems the exhaust pipe on it is 1 3/4 in., not 2 in. like I thought. Both places told me going from that to 2 1/4 in. is a bit of a stretch. So I guess I'll have to get it on the HHR one of these days when the "Little Woman" isn't looking.
Meantime I ordered a T-909, which has 2 in. pipes, for the Altima. Muffler guys said that would work. (I Hope!!)

 

all they have to do is make an adapter and swedge it from the 1.75 in on the 2.25 to the muffler. the tip after can be adapted or welded.

i would suggest another muffler shop that knows what it is doing

many of us that have 2.2's on our HHRs and the 2.2 has 1 3/4 in pipe and we all have and use the T924. so just ask them if they want to do the job and do they know how to make an adapter and swedge it to make it fit. you arent talking the whole pipe, you are talking a 4 in piece of 1 3/4 in pipe or 2 in to swedge it to 2 1/4.

if they have any kind of equipment they will do it for you. they just want you to buy theirs instead.

 

Well, I now have the CGS and the T-muffler installed. I had the CGS intake for a couple weeks now, and it had a good performance boost. I put the muffler on and notice maybe a slight performance boost. Soooo, my conclusion is that the 'real' need is the CGS intake. The CGS is going to give you the most boost. The muffler does at a nice sound; however I do not see much of an improvement from the OEM. But hell, for $28 bucks... it is worth it for the slight boost and good sound!!!
And yeah, I have the 2.2L, and I had to grind down the CGS to make it fit. It is working good now.

So now what?? What is the next mod to give us 2.2L owners more power? Header maybe? What will Header's give me (as in performance)?

I must admit though.... In hindsight I would have paid the extra $650.00 to get the 2.4L engine. Even though it is not a major upgrade from the 2.2L, it is still 30HP that I am missing out on. Oh well, I will wait till the Turbo or V6 version hits in 2008! Then I will upgrade. For now I am having fun with moding the HHR.

 

Does anyone have a sound clip of a IMCO T924 muffler on their HHR? I wanna know what it sounds like before I order it.
