Of course you can modify or change the installation to meet your particular needs/desires, but I'll address your questions based off the *intent* of the design. That said, many folks have made modifcations to the kit to make it fit their particular needs...
>>That thread is 13 pages long. Is there an FAQ? For example, <<
I don't have a formal FAQ, but happy to field questions.
>>I have a stock muffler. Can I use the rear panel delete?<<
Our rear panel does not work with the stock mufflers. I didn't realize anyone still had one
That said those that kept the stock muffler elected to keep the rear panel. In which case I have special installation instructions for keep the stock rear panel that I won't get into here. I will say that retaining the stock rear panel takes a lot of the "coolness" out of the kit since keeping the panel adds a layer of complexity to tilting... I think it was "MilehiTom" on the forum here that recently did this... for a while... then he later ditched the the OE rear panel and OE exhaust and is much happier now...
>>What happens if I don't? Which aftermarket muffler is most like stock and fully compatible?<<
All the after market exhausts fit and are compatible that I know of... Anything from Sector111 or BWR should work nicely... Closest to stock sound is going to be any of the quieter options... 8" larini, BWR/BOE Silent touch, etc... This would be a great opportunity to upgrade to the after market system to save weight, lower the temps out back, etc... The stock muffler is a pretty terrible part.
>>What does the support bar look like?<<
There are pics of the old support bar in the instructions on my website. It tied the two hinges for the boot lid together... I don't have a separate pic handy on this computer but will assemble a pic short order. We recently redesigned the support bar to tie into the drip rail of the boot and the hinges to provide even more support when the clam is up and the lid propped open. It's when the lid is propped open with the clam up that the strain is the greatest on the thin Fglass that the lid hinges mounts to. There are a few instances where someone's shirt tail or similar will catch on the open lid while tilted up that will cause a crack. I always suggest to close the lid when tilted up to avoid this, but sometimes "we" forget
Out of the 100+ units out there, I've only heard of this a couple times, but that's enough for me to address it. I've obviously had my hinge kit the longest and never had a problem, but.....
With this new support bar, there is even more support to help prevent this cracking issue. We'll be offering this as a very inexpensive upgrade for anyone with the kit and a standard part going forward.
>>Have cracks happened?<<
As per above, very rarely and when they have, it's always an operator "oops"...
>>Can you still access the battery terminals easily?<<
Yes and no... With the clam down, they're pretty hard to get to, but NOT impossible. With the clam up, no problem at all, as the battery is *right there*... This of course is part of the point. With the tilting clam, you have amny more options for mounting of components, cleaning, modifying, etc... We do offer an alternative battery mounting option to keep the battery in the boot. We use cable extensions in this instance. This is the original way we did it. We switch the current default location in the engine bay quite a long while ago because it's just "better" that way... Some will fix battery tender cables to the battery after relocation for easier "remote" access...
>>Will the clamhinge work with a Supercharger system?<<
Is the Pope Catholic?
I just don't have great pics on this computer, but the attached PDF has several images of the rear panel. 1 ont he dyno with a stock diffuser, and two with our diffuser... Those should give you an idea... Despite the pics all being with above diffuser exhausts, it works fine with below diffuser exhausts as well... I've seen some really nice work by a few our clients who covered the rear panel with a black mesh for a more stealthy look. They turned out very nice
Hope that helps!
