Performance
I have a 2001 C5 ,I already installed an X pipe and S mufflers ( Borla) now I’m getting ready to install headers and Hi Flow Cats would it be wise for some heat control from the headers to wrap them. Thank you in advance for your time on this.

Appreciate all the feebacks and knowledge. I do not track my vet. It's a 2003 convertible auto. stock with about 45k miles.
I'm leaning toward the A&A Supercharger. Heard a lot good things about it. Next thing is to find a good shop with c5 and A&A SC experience.
Thanks to all, you guys have been very helpful.

You may want to consider a cam as well, to give you more low-end grunt. A centrifugal super like AA needs some RPM to deliver full power, a cam will give you more pull at the lower rpms.

I LOVE my A&A. As others have said this will provide good reliable power with good street manners. I think you're making a great choice. You will also want a level V 4L60E transmission from RPM. When combined with a good tune, you really will have the best of both worlds. Your car is absolutely beautiful. You'll love driving it even more with the supercharger.

One thing I would definitely NOT do, and that is build the trans AT THIS POINT. As someone posted, budget for it now, or later. Reason being I've been lucky with my car, so far
, a 2000 A4 Vert. I have had 3 different engines in my car. The first was the OEM LS1. The next two were, and are, 427s. The last 80,000 miles my 4L60E has endured 2 different 427 engines giving it Hell at times. I also have a 3,200 stall Yank converter that been in for 80,000 miles. The only thing I've ever done to my trans is I've changed the fluid and filter at 100,000 miles. So my advice is to stay the course until you have a problem, if you do have any problems. When and if it fails, then have it built......

An A&A will put you at the bleeding edge of what the stock A4 can handle. I had originally planned to stick with the stock transmission until I had an issue. Well..3rd gear shredded on the dyno while they were tuning it. I had just had the transmission serviced to make sure it was in the best shape possible. As I mention it is bleeding edge, so it is possible that you'll get lucky, and the stock trans will hold for a while. However, it will likely fail eventually. In hindsight, I'm glad mine failed when it did. As a result, I upgraded the transmission right away. The new transmission functions better (shifts faster), and is 100% reliable. If you wait, you never know when the stock unit will go out. It might be at a very bad time, and leave you limping home or with the car in the shop instead of on the road. RPM has a backlog, so if you plan for it, things go smoother. If you wait until you have a problem, it could keep you off the road for a month+. After a discussion with RPM, I opted to stick with the OEM converter (which I replaced with a new unit). I have the 3.15 gears. Good luck with everything.
