will an intake change the sound of my exhaust. If so any recommendations on intakes.

 

No, but the JLT CAI will add 10hp and enough torque to have taken .15 secs and added .9mph to my passport timer. If anyone is considering a CAI stystem I highly ecommend the JLT. Mark

 

cai's dont ad much more than 5hp, on swee99's car it prob helped alot because his car is heavily moded but on a close to stock GT it will be almost unoticable.

 

Best single mod is the steeda timing adjuster as sold by Brenspeed.com. Our 4.6 motors are preset for 10* timing advance at idle and there is no adjustment, until this timing adjuster came along. It allows the timing to be advanced up to 10* more advanced or 10* retarded. I even added it to my Predator tuner and was able to add 6* of extra timing without knock but 93 octane is suggested but I know of one guy who got away with 89. I used it untoil I was ready for a custom tune which I also got from Brenspeed who gives 3 custom tunes for 3 octane levels. My SCT is on it's way back from Brenspeed with a tune for 100 octane in place of the 91 octabne tune. My timing adjuster is available if interested PM me. Not many mods in and of themselves offer as much. Not UDP's, 75mm TB/plenum or most intakes. Mark

 

Al I see you have been a member for nearly 2 years yet your mods are minimal. That's cool as even with all of the mods I Have which are gears(4.10's), UDP's, JLT CAI, 75mm BBK TB/plenum, PYPES catted X-pipes/catback w/RacePro mufflers and 17"x9"/10.5" Bullitt wheels wearing Sumo 275/40's and 315/35's in the rear, I did not gain a lot. I got my 1/4 mile time down by .5 and my trap up by 5 mph. All of this cost me well over $3K.
Don't get me wrong as I do enjoy the car and having it be a convertible makes it much more fun. The Steeda timing adjuster and UDP's have gotten my mileage back where it was stock which is 18 mpg in easy driving. Mark
PS: One of my best mods was a set of NGK platiinum plugs!!

 

Nah i only have been here for 10 mos. Its about to be 1 yr though? Yeah i wanted to pay the car off first and then mod it. Now that the car is paid off the mods will come slowly. Plus i got school expenses and other crap like that that its hard to put money in the car.

 

+1 on the JLT. They even have ram air kits that you can order to match the color of your ride.
