Dynatechs bolt right on and so do the cats. No cutting or welding.

Re: header that you use?
Dealer installed mine. They also checked the bolts a few months later and all was fine.

Re: header that you use?
No. As far as I know, they make long-tube only, hence the reason I went with them. It's my understanding that short-tubes are a waste of money.

Re: header that you use?
Love my Dynatechs....good power, good quality, easy to install. Hooked up with high flow cats and Magnaflow the sound is amazing.

Re: header that you use?
Plan on getting a higher end programmer or custom tune when you free up your exhaust w/ headers, high flow cats, etc... The increase in noise fools alot of people into thinking they're running better when in reality you just lost a bunch of torque. I'd almost get one of the mail order custom tunes now that the price is down over a hand held programmer.

Re: header that you use?
It sounds like a lot of guys are agreeable that the Dynatechs are the way to go where's the best place to buy them for a reasonable price?
Jegs or Summit? Or some place else?
