You need the tuned exhaust pipe!, it aids in the combustion process by forcing you fuel air mixture back in to the engine...r/c engines don't have exhaust valves or intake valves, thats why they have that tuned pipe. the comparison to a 1:1 and a nitro r/c are way different
I've made power in a late model truck by pulling the mufflers and running a supercharger....sometimes there was sparks from the overheated carbon deposited on the inside of the pipe, but mostly cause I wasn't the best at shifting gears at the time!.....my half ton was killer loud you could hear the dual exhaust from a 1/2 mile away... People would call and say I thought you were driving up my road...and I'd be all nope!

You buy exhaust upgrade kit cause people like alipinehyperlite and nikko508, will pull you over and site you for noise pollution.....I always argue this rule/law mainly cause with my loud pipes I have yet to run smack dab into a deer or anyone for that matter, people and animals don't wanna be on the road if they can hear you coming a 1/2-1 mile away!
