We just took delivery of our 2009 GT silver premium. So far, it has been a great car with good HP and excellent handling. Can anyone suggest a way to increase the HP just a little and increase the exhaust just a little also? I don't want to void the warranty from FORD.

TIA

a tuner, cold air intake, slp loudmouths

It sounds to me like just the exhaust would be OK for you. I agree with getting the SLP Loudmouth, that's what I have and I love it.

SLP for sound bur he wants some power to, Get an electric Water pump I been told those good for 30hp but maybe they were pulling my leg lol.

11.2 to the wheels but that's pretty good compared to intake price wise since you would also need tune for intake to work and I don't think you do need it for pump.

I see your 11.2 rwhp gain and raise you another 20rwhp.

You should combo it with the tuner to save some $. You will spend like $200 more over the pump, but will see a bigger gain, plus you get a tuner out of it.
Also, all you need for exhaust is to get an axleback system. I like Bassani or SLP, just search youtube for the sound you want. It all opinion, get what you like.

I have never personally heard SLP's but Bassani are sexy.
