What would this exactly do for my car?

http://www.rksport.com/product/p_02091062/view_detail what would this device actually do for my car and is it worth it?

make it spark better, and faster. Mostly used for NOS. Figure it this way, when you hit the gas this will make sure that the spark gets there quicker. Aa far as it's affects, well that depends on your motor and what has been done to it.

2.2 with a cold air intake, here in about 2 weeks gonna have new headers and cat back system installed

By the way, what would the best headers be for the price? Anyone or any groups of you, have something that you really like and noticed a big difference from one brand to the other?

The power core basically just gives you a hotter spark, but you will only notice a difference if you are running boost. So if you not, there are other ways to blow money. Its header singular. We only have one. I have the Pace setter ceramic coated one here in a box waiting to recieve its purpose in life. Ran me 230 shipped. They all basically do the same thing, but stay away from the black painted pace setter.

he should be getting much better throttle response with that ignition setup... along with like an extra 5 hp and 5 ft-lbs of torque. but crj is right, there are better things to spend the money on

hey CRJ just random question,

Thinking of getting the 4 to 1 Ceramic coated header from pace setter along with their catback exhaust (current catback was a lousy job with a custom bend) and a high flow cat. What do you think?

here ya go for links

i got a full chrome header 4 to 1 on ebay for $120 shipped

All i am going to say is you get what you pay for. Thumbs up on the header, i think you can do better than that cat back. Not everyone has the resources that i have so i am not going to list what i have going in for the header back. BUt i think a magnaflow or RKsport cat back would be better. OH and don't order through High rev. their customer service suck ballz.

jebus. 500 bucks for a good cat back eh? I'd better start saving. I was lured by the low price of that pacesetter cat back, anyone have anything to say about that one?

In my world i buy a cat and a muffler and take it to the local muffler shop and have them install it. This last time i crawled under there with a welder and did it myself but when i put my new header on and stuff i will go to the shop. Cat-back systems have their advantages if you pay the price
