Relevant posts from the recent SRT Engineer chat. See below. These, taken together with the above news mean to me that the bottom line is that you spend your money and take your chances. If something goes wrong, it has been made clear that Dodge's warranty will not cover it. Is there a warranty with the headers? And, if so, what does it cover?

The problem is we really don't know what the long term effects are since we haven't had an opportunity to do that kind of testing. It may be ok ...........

Can you please tell us, once and for all, whether there will be a Mopar horsepower upgrade for the 2008 model or not. There has been much speculation that such an upgrade to the 675 hp. range is forthcoming sometime in the future. Recently, however, one source advised that this is not going to happen.

We continue to look at opportunities but at this time there are no definitive plans to release a kit.

I am seriously considering adding the Belanger exhaust system to my ACR when it arrives, however, wanted to know if something was coming from Mopar that I should wait for. Thank you.

Understand that you're looking for something to get a bit more performance however while we have some experience with the Belanger system we can't endorese it.

Bob,

The 2008 engine is a highly tuned and highly stressed engine. We left few stones unturned in the development or calibration process. Achieving 600 HP required that many of the parts be stressed to their limits and the pistons are one of the most highly stressed components in the engine. If the customer modifies the engine to increase the output by any significant amount (more than just say headers, i.e. supercharger, turbo, NOS), a quality forged piston would be a good idea. We don’t currently offer a replacement piston but many of the aftermarket suppliers could probably offer a good replacement part. Follow their recommendations for fit. Also be careful to make any adjustments for balance if the weight is much different than the stock piston. Don't forget to use a good engine builder and make sure the calibration matches the modifications!
