great to hear that they are standing by their work; by the way what did you have done to the car? is it the full upgrade and ifso how is it for traffic driving etc
Hennessey +1 -- Exceeding Expectations
I already posted about the work I had done at Hennessey's shop near Houston, but the rest of the story deserves note.
After I drove the car home, when taking hard right turns (something I hadn't done on the trip home), I noticed an ill-defined sound coming from what seemed like the engine bay, and I was concerned. Also, the CEL came on.
I emailed JT about it at maybe 8PM that evening, and the next morning he called me and said they wanted to fix it pronto. What they did next surprised me and earned them my trust in a major way: The next morning they had one of their transporters come to a place of my choosing (I chose a large parking lot 5 minutes from my house), pick up the car at 7:50AM, and take it back to the Hennessey shop (it's about 2.5 hours from western San Antonio, where I live). Their transporter was very professional, and he called letting me know of his location and ETA. The car was returned to me that very afternoon about 5 or 6 PM. Incidentally, the problem was a header flange that had rotated and was contacting the frame when making right turns.
They noticed that I had kids, and asked if I would like a mod to the NAV that would permit the playing of DVDs in the car. So, they installed that and it works great -- now the kids can watch a movie when riding with me (it's shameful that my kids would choose the minivan over the 600HP V because of the lack of DVD play). Of note: no drinks, no popcorn (if you were wondering)!
Here is the email that Dave Golder sent me:
Sir I just wanted to take a moment and apologize for the mis-hap on your car. The issue was a header flange had rotated which caused the noise and the CEL was due to a catalytic converter setting in the computer. Since we installed High-Flow cats the computer thought it was missing the cats so we had to make an adjustment inside the ECU. Again I am sorry for the problems and I appreciate you letting us resolve them for you. I hope you enjoy the DVD/NAV box. I have one in my CTS-V and it is a nice addition. I felt that was the least we could do for the issues.
Our staff does take pride in their work, and customer service is important to us, and anytime we let someone down we try to learn from it.
Regards,
Dave Golder
I have had two other cars modified (a '98 Trans AM WS6, and, of course, the '01 Audi S4). There were issues with those cars that were worked out, but no one has ever stepped up like Hennessey did.

I had the CAI, AR Headers and cats (without the Corsa mufflers), and a tune. I detailed my impressions in another post, but I am very pleased with the sound and performance. It drives in 100 degrees Fahrenheit like it did before in 60 degree weather. Love the sound. At first, with the AC on full, my wife wasn't sure she could hear a difference in the sound (not at all obtrusive), but when the A/C fan isn't blowing full-force, you can hear the exhaust, the supercharger, and the rushing of air. These are all mild, but welcome additions to the aural feedback of a powerful car IMO.
wow thats exellent customer service. I think thats the advantage sometimes in using a mainstream shop like these guys especially after they have obviously learned from supposed past mistakes.
Wish all of our forum suppliers responded to problems this quickly.

Thanks for the kind words sir. I am glad the kids will now ride in the V. Enjoy it. I sure love mine.

How much was the package? and do you know how much the higher tiers were?
I just want to +1 the comments on Dave Golder. I bought his stock CTS-V wheels/tires about three weeks ago. They came to me in exactly the condition he described, and he even waited to ship them until I was back in town after my recent vacation. Got them last Wednesday. :thumbsup: They'll be my winter wheels and I'm already looking forward to seeing what a set of Pirelli Sottozeros will do to my car...and now I've also got a spare set of summer tires for when the originals wear out. 
Thanks, Dave!
Thanks, Dave!
You can PM me your email address and I will be happy to email you a catalog and price sheet.How much was the package? and do you know how much the higher tiers were?
Sounds like an excellent company. Of course, I've heard of Hennessey before but I've never heard of a personal experience. Awesome!!
So, do Hennessey modifications void the factory warranty? I know that some of the big aftermarket companies guarantee that their work is 100% factory warranty agreeable. Is this the case with them?

Depending on the upgrades done it may or may not effect your warranty. If we do something like a pulley then it could affect your power train warranty and if we install one of our kits then we warranty it. You just put on a Corsa Exhaust then nothing is affected. But no your whole warranty is never voided. If your power windows stop working then they must cover it. The law states that the modification must have played a part in the failure for them to decline warranty.
I understand the laws on warranty coverage for aftermarket parts, I was just hoping for more than what was realistic.Tony,

But, you answered my question. Thanks.
