Started with Akras slip on just for the sound. Didn’t think I’d need their headers. I found the bike running out of steam especially in 4th thru 6th over 6 to 6500 rpm’s. Same performance with stock slip on. Decided to add the Titanium Exhaust Manifold to match and see if it helped. WOW, DID IT EVER!!!!!!!! Didn’t have any complaints before but now the bike it so much smoother. Throttle response is much improved and no more running out of steam on the top end. Just wish now that I’d installed Akras full system from the beginning. It is a tad bit louder when the throttle is twisted but just fine cruising. Money well spent. Not concerned about more power so didn’t go with the foam air filter. I just think paper does a much better job removing the fine particulates that cause cylinder wear. For those that have done this is anybody experiencing any lean fueling conditions? I’ve heard the ECU should compensate and at this point I haven’t ridden it far enough to notice. Short ride today but tomorrow I’ll put a couple of hundred miles on her and see how it looks.
