Default 90 jett LX full pipe stinger diameter

Running a 90 jett lx full pipe ,(no muffler) My stinger dia. is .320. comparing a dubb muffler with stinger .315 to .350 because of hex shape.
On 15 nitro I get 15,000 to 15,500., plug ware is good. using a MC 59..
Orignal max pipe was close to .400. Also pipe lenth is 14 inchs form plug to first band at flat spot. Had go small on stinger
to get better fuel feed from pressure. Looking for feed back if any , for more performance ?? 90 is in an cermack alley cat. Prop is apc 11/8


thanks rich b.

I run my own carbon fiber tuned pipes on all my engines, including 5 Dub Jetts. That being said I have never run a 90LX.. I know who has though... Why don't you shoot Dub an email and ask him. Not only is he a great guy, he built the thing so he knows how to tune it. He will be able to give you starting pipe length and outlet diameter.
