stock exhaust or new factory 7?

[baseballertc14]

I am now working on a project for my graduation project at school and im cleanin tha old stock exhaust because of all tha rust thats on it. Making it all shiny and clean. And now im wonderin if i need to buy a new exhaust system since i am putting a big bore kit on the four wheeler or if i can save my money and leave tha old system on even thought it might not help my power.

And how much extra power and torque does a factory 7 exhaust system do for a fourwheeler?

don't know the specs, but i can tell you it's a good pipe.
sounds badass. def louder than you'd expect from a 200cc engine.
i think that it's more for a mid-range boost though. not sure if it's the best pipe for high end. it all depends on what kinda engine you wanna build and how you wanna modify the cylinder.

stock exhaust would kill a big bore. Factory7 ,Power-pros, and Dyno-port all come highly recommended for big bore applications plus factory7 has a nice finish on the pipe and the silencer comes in your choice of colors.
if you decide later that you'd rather just do some light modds to your motor
id suggest Toomey

...what would you consider "light mods"? ......anything besides bore, stroke and port?

 

[SMITTY]

also is the Factory 7 the same as a dyno-port because they look kinda similar.

 

[Braapbraap95]

lol because they look similar?

 

[SMITTY]

No, but what I mean is that f7, power, and I think lrd are roughly the same. I may have it incorrect, but I think you know what I mean now. I've been involved in this industry/sport for around 19-20 years, and sometimes you see one brand manufacturing a product for a couple other labels to put there name on. Understand what I mean? It's kind of bogus how it works. just wondering if dyno-port has any copies out there? I know alot of you guys are sick of the "pipe" questions so I try to use the SEARCH as much as I can too.

i have talked to FLOTEK about this and to what i understand Power Pros maks the factory 7 and LRD. They just put a different badge on them. I am unsure if the Dyno Port is the same. The pipe may be the same but the silencers are from 250r's

if you get the big bore, go with a dyno port high volume. its designed for the bigger bore.

and jackson the dyno ports way different then the LRD

 

[djack12]

i said i wasnt sure, i know the Dyno Port uses the 250r silencer.

Please wait until I post the data from the pipes until you buy one.
What I can tell you so far FMF SUCKS!!!!!!!!!!!
LOL
LOL
The Vito Pipe right now is kicking butt on this project; but I am not done yet
I still have 3 pipes to test

 

[specialized7]
