New mustang gt 04 40th edition .....undecided about exhaust? Factory sounds OK but I want it a little louder but not too loud!!! also would like cold air intake. I was told it could possible void warranty???

 

Welcome to the forums. Good luck with your new car. Seems like a question often asked, with no clear answer. Most indicate, that it doesn't, then others say its the dealers call, based on what they think the modification could have impacted. Engine problems, when considering exhaust or air intake.

Best of luck.... I will be leaving my intake and exhaust stock a bit longer, I am at 800 miles on my 05. Kind of enjoying the car, and giving potential manufacturing problems time to surface. Just in case.

 

Welcome to the forums. Your gonna have to move this to another forum to get opinions. You can go with flowmaster if you don't want your car to sound too loud. And as for the cold air intake. It shouldn't void your warranty, it depends on the dealer though. Have fun with your car.

 

why not install a cold air and if something happens u need to use ur warranty put the stock intake back on.?

 

It shouldn't void your warranty, if something were to happen to your car, they would have to prove that what you did to it caused whatever happened, which would be very hard if all you do for now is intake and exhaust. But just in case keep your stock intake and throw it on if you need to go to the dealership for any warranty work.
