Default Arrow header question

Hello all, I have 2007 F4 312R and was thinking of installing the Arrow high performance header. I am keeping the factory Arrown slip ons as they dont look to have any restriction and look good also I have already installed the Arrow high performance mid pipe which replaces the catylitic(?spelling) converter.

TTHE QUESTION IS: WILL IINSTALLING THE HIGH PERFORMANCE ARROW HEADERS MAKE A BIG IMPROVEMENT IN THE BIKE PERFORMANCE OVER THE STOCK ARROW HEADERS?
I THINK I RECALL READING ON THIS FORUM THAT A MEMBER HAD INSTALLED THE ARROW HIGH PERFORMANCE HEADERS ONLY TO COME AWAY WITH A 3-4 HP GAIN AT THE REAR WHEEL.
IF THAT IS THE CASE i WILL PASS ON THE UPGRADE. 3-4 HP ISNT WORTH THE 1800$ COST.

Thank You, Jake

Hi Jake

I have the ARROW 71036CP - Full Race System in full Ti. I believe that you would be lucky to gain 3-4 RWHP with headers alone.

IMHO, $1800 will buy a Microtec ECU that will transform your bike, and deliver miles of smiles. Forget bolt on's, fix the throttle. No more high temps. You won't regret it. You will get your HP increase, with manners

Chris at X-Bikes is your man.
