Re: Dana exhast?

I just checked out the website and the price is more than competetive....Do the aluminum risers have the seperated runners? What is the effective length of the runners with each of the risers? Looks to be a really nice set up. Thanks- Chuck

I have sold Dana exhausts in the past to quite a few customers and have had no complaints. Awesome looking exhaust. Just my two cents. Steve Snider

Thanks for all the good feedback. The aluminum risers do not have the individual runners. That option is only available on our Vortech stainless steel risers. With the Vortech stainless steel risers the runner length is 27". We currently don't have anything for 5" exhaust.
