    I'm trying to decide which route to go to between the X pipe and H pipe any advice or recommendations? Thanks
  2. Exhaust
    Hey, I am planning to get a custom catless exhaust system and I am wondering how much harm it would cause my GTO to drive without a tune until I can get an appointment at the local tuning shop.

    Hello, today I took the heads off of my 2005 gto and while I was cleaning the gasket material I managed to scratch the head. I was wondering if it’s anything to worry about, or should I get it resurfaced. I plan on boosting the car but also keeping my budget down. Is it something I can seal...

    Hello everybody, My name is Marc-Antony. As the title states, I have a 2006 Pontiac GTO. The problem started one day while I was driving and my car wouldn't shift out of any gear.
