I just finished installing the stage II and 3’ exhaust combo from ADM Performance. The power is amazing. I went with magnaflow muffler. The sound from the 3" exhaust is nice. The HHR is still quiet enough to be on the phone with a customer while driving down the freeway. (bluetooth headset) That being said with a WOT it can be heard. The exhaust tucks in just like the stock exhaust. I have seen many after market exhaust hanging out from the bottom of cars dragging over every bump in the road. I was also able to make sure the pipes are not banging on the under side of the car. This is a nice fit. Two thumbs up on a job well done.

I am hoping to go to the track this weekend and get a time slip or two.

 

Gald to see you got it installed with out a hitch.Post some good time once you get back from the track...

 

My best time was 13.7 last weekend with a 2.43 60 ft.

I need a better set of tires. 1st and 2nd just spin.

 

post a time slip so we can compare 60' and 1/8 mile, Awesome times!

 

Damn that quick for exhaust and tune. Props Andy and the boys at ADM.

 

My Time Slip

60' 2.43
330' 6.10
1/8 9.11 mph 83.73
1000 11.63
1/4 13.79 mph 104.34

 

not bad at all. I think with a tad bit better driving a colder weather I can hit the 100 MPH in stock tune. ET's suck for me LOL

 

You made up some serious ground after the 60ft......my best is a 2.34 60ft and the et was 14.16 at 103. I wonder where the difference is. 330 ft 6.3, 1/8 mi 9.38 at 79 mph 1000ft 11.9. What technique did you use? NLS and where did you shift at. Did you cross the line in 3rd or 4th? I'm just into 4th crossing the line. Stock tires 1/2 tank of gas. I know, a lot of questions...just curious. Nice work!

 

I am not sure what the difference is. The shift light is set to 6150 on the Aeroforce gauge. I did not use TC on this run. I did use "no lift shift".

 

Nice times,I am glad to see we finally got some local track time for our exhaust and tune.

I may be selling the intercooler off my car...Interested?
