Hey guys, I know this question has to been asked about a thousands times maybe, but i was wondering if putting a invidia mid pipe and my Megan axleback and would make the car a tad quicker or would I need to get the tune and intake from rr racing to see actual gains ? I currently am running just the Megan axleback and I feel like the car can be peppier without having to put headers in. Any answer is appreciated

 

I personally don't have experience with an aftermarket exhaust (yet..) but from my research and from what I know there would likely be a slight gain in HP (maybe 5-10 crank hp?) without headers. Of course headers would improve this even more. The RR Racing tune should utilize the axleback more then the stock ECU flash, and would also likely get you even more hp gain then just running an aftermarket exhaust/mid pipe.

I have the RR racing tune and have noticed a more linear power curve (on top of the improved redline).
