Ouch!

 

What model number / size of IMCO was used?

 

Model # 924:

 

does anyone know when they are going to make a supercharger for the 2.4L?

 

Mike (SoCal)....
Any Dyno #'s on the Muffler (only) add-on yet???? I've 'RE-emailed' (4/17/06-2nd time ) Gibson with the following:
"I've e-mailed over a month ago and haven't received a response to date. I'm interested in your cat-back exhaust systems for the 2006 Chevy HHR and would like some additional information (Dyno numbers, sound clip, fitment issues, etc...).
I know of several other HHR owners, as well as Mike at SoCalHHRs.com, that have asked for this information first-hand to no avail."
... additionally ...
"... I'm requesting a response (good or bad) regarding performance figures to back written claims as well as a sound clip of this exhaust on this vehicle. Even if this information is non-existent, M.I.A., or simply "made-up"- please e-mail to advise. At this point, simply receiving any response is better then not receiving one at all."
Guess what... NO response (what's new?) Not only trying to get some answers- hoping they might go for a 1-time "group buy"... if I can only get someone to reply!
What ever happened to 'customer service'????
As a final effort, I'm thinking about calling Gibson direct (REALLY interested in thier cat-back) but feel I shouldn't have to beg to give someone my money!!!
So... back to the original question- any dyno numbers from the #924???

Thanks!

I have an interesting side bar to the IMCO 924. it is lil quieter now that i have had it a week. Mike at Socal said it would gradually get quieter.

I had one of the Tornado gadgets that i bought on ebay and tried it before and it didnt seem like it did anything in pick up or mileage. I was going to give it to Txsman2930 and then got to thinking, wonder if it would work better w the new muffler. and Txsman had asked me the same thing so i put it in and this time instead of putting it by the housing i put it at the end in the fender well.

well initial findings-
the pick up from start was quicker and got rid of some lag that was there.

rain and high humidity usually make it lack pep and today it was flying in high humidity and rain

yesterday it was dry and cool and it was smoking.

i have a lesson at 11 so i am going to take it out and see if it is different or my imagination.

going to leave it in a week and i can tell you that before i left it in 2 fuel ups and no considerable or even a small difference in MPG. that part sucked. seemed to have a lil more pep but nothing like i would want to tell anyone about.

when i put it in this time the change and pick up was very noticeable. will fill you in later on how it goes.

 

Ooops!! Just reply'd to your post in the 2.2 forum CJ (Sorry).
One thing goes without saying... (just want to verify) your using the same octane on fill-ups, right?
Interested in the results.

Thanks again!

You guys can change exhaust if you want, but I am getting the ChevyHHR.net decals, the ricers tell me decals are worth 10-20 hp each !!!

 

Don't forget - the SoCalHHR "Flame" stickers are worth an additional 50hp!
Plus they make your HHR look faster standing still!

 

If you cut wind.. you can get another 10hp...
