I'm thinking about getting this muffler. Maybe not right away.. but perhaps further on down the road.

I like the way my car sounds, but at the same time I keep thinking that I want a but more of an aggressive sound to it, but not too much. It seems this IMCO T924 is the way to go, a lot of HHR owners certainly favor it.

My only question is, how does it effect the "inside" noise level? I mean, inside the car, is there much difference?

 

First question for you is, which engine do you have?

If you've got 2.4, then T924; if 2.2, then T909. Wish I'd known that before I put the T924 on Nellie.

The T924 is set up for 2.5" pipes (size on 2.4), while the T909 is for 2.25" pipes (size on 2.2).

As far as the sound goes, I find it a little obtrusive, but not bad enuf to go back to stock. It doesn't sound "ricey".

 

2.2L Engine... which is why I posted my question in the 2.2L Forum

Didn't know there was a different Muffler, as the T924 is the only one I've ever seen mentioned.

 

First off, my wife and I both love it.

It is louder in the cabin, but I don't think it's obnoxious.

In my opinion, it's worth it.

 

I have the T924 on the 2.2. Took a little modification for the welding, but it when on fine. The sound is barely noticable compared to stock. Not much louder at all, although it does produce a little more sound while gunning it, not even close to being obnocious.

 

obnoxious**

 

Doh, Ishudda figured out dat dis wuz in da 2.2 area

If you search for T909, you will find a couple of threads that adress the size disparity. The T909 is the one you want, it will fit nicely with no need for adaptors. It cost me an extra $25 bucks for the adaptors to fit the T924 into mine.

 

I had the 924 put on my 2.2L and love it. No extra charge here to haveit installed.... Might want to check with local muffler shop...but I did purchase mine from them which could have made the difference too.

I don't find it obtrusive...but then again...I play my radio pretty loud too.

 

I love mine. A little more noise when you really put your foot into it, but that is good. Cruising on the interstate, there is no change.

 

Same here.
