whats a good pipe for a serval for trails? my setup will be +3 a arms +4 axle -2 swingarm. i was thinking pro circuits or maybe 916s? i considered cpi inframes but that might be to high of a power band for what i want. i was running that dyno port pipe with the larger stinger tube from my turbo and that pipe made awesome bottom end power, but now that i got rid of the turbo setup im looking for a decent low to mid pipe.
