    Tyga Dual Undertail Exhaust (Prototype)

    Hoping Tyga puts this system into production and maybe we can sway them with enough interest. Best looking Undertail exhaust in my opinion and would probably be a decent price coming from Tyga.Photos gathered from the Tyga Performance site.

    Aftermarket exhaust/ slip on

    Hi all, Just got a Hotbodies MGP Growler slip-on exhaust for Honda CBR25, from a friend. Just wondering if I can use its silencer with an arrow mid pipe on my rc 390? If so, do I need to tune my bike?

    PCV Installed Now Backfiring

    Need some help. I installed my Arrow GP exhaust and PCV, and I'm running the stock air filter. The PCV has the Arrow fuel map installed. When I decelerate, I'm getting backfiring. Is this normal? Is the bike running too lean? Too rich? Any help/suggestions would be appreciated. Gary

    Dyno Questions

    So I received my Arrow GP exhaust and PCV last week. The PCV came with the Arrow Fuel Map installed. My questions are: 1. Should I get the bike on the dyno prior to installing everything to get a baseline? Is it a waste of money? 2. Does the tuner need the dyno baseline data to tune the...

    Akrapovič Exhaust - Catalytic Converter

    Does anyone know if the Akrapovic exhaust that KTM offers on the Cup Bike has a catalytic converter or not? There is a large canister behind the engine. This is a track bike only. So there is no need to catalytic converter. Unfortunately there is no information on Akrapovic's website. Akropovic...

    Arrow GP2 db levels

    Has anyone who has a Arrow GP2 exhaust installed measured the db levels? I'm ready to get a different exhaust, and the Arrow is one of my choices. But the track I like to go to has a 102db restriction, so I'm trying to comply with that. I've searched the forum, but didn't see any threads...

    Bottom Line: Remap needed for aftermarket exhaust???

    So whats the verdict here? I have read the bike does and doesnt need to be remapped when you install an aftermarket exhaust. I know the Akro exhaust has a remap... but I am not looking to spend that much, plus that can is HUGE. Not a fan. I am interested in the AHM ZR1 exhaust, or even the GPR...
