Hey,
I have a 06 GT with only a Air Raid cold air intake. Im looking to get a SLP loudmouth axle back exhaust. What should I get to help increase my horse power? I was thinking about headers and a throttle body. Maybe even a chip, but i dont want to ruin my warranty. Any Ideas?

 

How much money are you looking to spend? Are you going to install parts yourself? If its under 1k I would get gears and a handheld programmer like SCT or Diablosport tuner. If warranty is an issue you will have to get the Race Pacs that Ford Performance Parts sells but it all depends on the dealer and how knoledgeable they are. There are some dealer that sell and install high performance parts,check out if your lucky enought to have one in your town. The lazy or untrainded dealer will void and blame an issue on a aftermarket parts even though they cant prove that it caused the issue. Theres two sides to a story but you can install gears and a handhelp programmer then when you take it in for service you can put the stock tune back in.
