Hindle under tunnel

[birkebeiner]

Do I have to do any other mod if I put on a full Hindle system? Like fuel controller, spark plugs, air filter mod, etc???

yep...needs fuel and airbox mod ( or filters )..spark plugs are optional...I didn't run them my first season but have had them in the last two. Airbox mod is important or you will lose some hp/tq down. It makes a major difference. If you already have the exhaust...just get the others components from Hurricane...if you don't have any of it you can get the kit from Hurricane..bolt on and go!

Thanks

Don't have any of it, yet. If I need to add a fuel controller it will bring up the cost quite a bit. A set of filters should be doable tho.

How much difference is it with the exhaust and filter mod? Are you running under tunnel?

The kit from Hurricane is $1400 for the exhaust, PC5 and airbox mod...filters are roughly $100 more than the airbox mod..just to let ya know. I wouldn't recommend running without a fuel programmer...we saw some lean spots around 6500 rpm...I wouldn't take the chance. The exhaust isn't an under tunnel system...it just uses stock plastics...so it goes into the stock location.

Exhaust only vs exhaust/airbox mod is night and day...the airbox mod brings back any low end loses ( and there was some ) and makes 6+ hp on top end...you leave alot of HP on the table without it.

this thread might help ya...
