Using various mandrel bends and an off the shelf "fart can" style muffler for exhaust and various mandrel bends for intake. I can get pics soon. Keeping 2 1/4 for exhaust and intake starts at 4" on the filter and down to TB size right at the MAF. Helps create a velocity stack effect!

I will be getting into the computer soon (hopefully), and will see if that can be removed, and some changes made to the mixture ratio, neutral rev limiter, shift points, and firmness.
Let's see if we can't come up with a "tune" for the HHR!!

Just left a post on Gas Peddle Issue...
On I-5 several weeks ago, had a clear freeway for a little bit. Punched it, baby!
Hit 105mph, before I had caught up to others. Wished for 110. It was there but I had to slow down for the others......
Love it.

Twice I've had it up to 115 until I realized the clicking was the antenna bouncing off the sun-roof. Will have to try again as soon as the new "shorty" gets here. Plus, after reading posts about having a gov, I'm not sure if I actually hit 115.

I left the house early this morning (4:30am) so in a lil bit of a stretch, i put the pedal on the floor up until the dang speed limiter kicked in at 108 on the nose... dang conspiracy to control us... I'm waiting for HyperTech to come out with a chip modulator... I have one on my 04 Silverado and I love it... speed now at 128, changed the gear shift speeds, firmness and a couple other things...
