Hey ramit........

Sorry for not answering sooner, just came in from work.

I had CampersWorld install the exhaust brake in Jan, of 07 for a total cost of $1595.65

This past Jan, of 08 I ordered from Pac-Brake themselves the air bags and installed them myself for a cost of $278.52

I use the exhaust brake 24/7 and yes I feel that it does save some wear and tear on my brake pads. Where I truely benefited from them was when I'm towing my 5'ver. She's 37' weighing in at 15k dry. Here in the south it's not too big of a deal, but as in last summer when I towed her up to Yellowstone and back, the exhaust brake really saved us some stress. Going down alot of the swtich backs in the mountains, your brakes remain cool instead of heating up from prolonged use.

One other advantage that I have thats working in conjuction with the exhaust brake is the ATS Co-Pilot torque converter controller inside my cab. I have it set so that the t/c locks up at a low speed, thus enabling the exhuast brake to stay engaged down to about 22 mph.

Regardless of if you may happen to have a controller or not, the exhaust brake would be an asset to your rig when towing, or should I say stopping the rig.

You had asked about the warranty issue. I have not had to take my truck to the dealer for warranty work as of yet. No doubt that with all the upgrades that I have on my rig, they'd refuse me right away.
On the other had from what I've heard about most dealerships, (not all now), they'd void your warranty if they happened to see one of those christmas tree air fresheners hanging from your mirror.

Good luck with your decision, and research as much as possible so that you're satisfied. I really don't think that you'd be dissappointed.
