I have just installed your exhaust brake system on my 99 dodge ram 2500 and going over the mountain passes on our vacation has been great. NO MORE WHITE NUCKLE DRIVING… the exhaust held my trailer at about 60MPH on the downhill in overdrive in most areas and in the 8% area i locked out the overdrive and was able to go all the way down without touching the brakes ONCE instead of my normal slow from 80 to 55 and back. I am now a customer for life. I have the trans lock along with the banks brake, chip, and the bighead and my truck is now better than when new. I will continue to upgrade with you … the best part of my upgrades so far… NO SMOKE and just pure awesomeness… thank you!
