Hello from Fla. Newbie here

I have a 09 srt-8 challenger , I have had the car one year ,it has 4500 miles on it , I have 3 mods, predator tune , nitto's , and factory headers with with the new factory pipes . The car has a great sound but did not improve HP, the headers are very small in diameter, I would suggest to anyone wanting to buy them , to not waste your time or money except it is still under factory warranty . The best I have turned is 12.95 on a 65* nite and moderate humidity, I did the same thing a month earler with out the factory headers , other wise it likes 13. teens , it is automatic . My question is about adding a new throttle body , How big is the stock one? and if I change it ! what mm should I get ? Glad to be here , Thanks Bob

Welcome From San Diego, Ca.

although the headers are from mopar i don't think they are covered under your warranty (definitly not if the part number begins with a P*******).

Ralph is right on the warranty but don't sweat it.

I'd stick with the stock throttle body for now, and spend that money on a Diablo tuner. With the long tube headers and perhaps a cold air intake you might do better to get a custom tune done on the car. Than to get a bigger throttle body, which is going to also require a custom tune to really take advatage of.

correct don. they can not void your cars warranty just the headers or any failure which is caused by the headers (which should be nothing except maybe a cat failure). sorry if i was unclear. it made since in my head. lol
