Dyno Don headers
I bought a set of Dyno Don headers and front pipes. Installed them this week. Damn........I couldn't be happier. The quality is outstanding and the fit is excellent. I had to bend a brake line out of the way and that was it. No other clearance issues at all. It all looks like the way the factory would have done it. I'm highly impressed.

Re: Dyno Don headers
My headers should hopefully be arriving in the next few weeks. I will be mock fitting the ypipe to the Magnaflow catback and making any cuts needed so that I can then take it back out and have it sent out to be coated. Crappy part of all that is my car will be down all summer unless I can hold off until the Fall.

Re: Dyno Don headers
All Dyno Don needs to do now is make LS swap shorties.

Re: Dyno Don headers
Top notch headers and Y pipe. Fit and finish is excellent. They help pull 380RWHP on my 383.
