I am looking to purchase a new exhaust system for my 2005 GTO. My local shop recomends the Dynatech long tubes. What is everone thought of this system. My shop also recomends a custom tune after the install, do I need to tune my car?

Thanks - Ron

You will hear different ideas about the Dynatechs, some good some bad. As far as the tune, it will make the car like the headers alot more. The tuner can see if your car is running rich or lean. If your wanting the most out of your car go with the tune plus its good time to get your fans switched on ealrier if you have a 160 thermo, or any other mods.
