so if i am understanding this correctly there only Flashpro for these 9th gen and not full kpro like the older models? and it uses a down pipe not actual headers as well?

what do you guys think of ultimate racing full DP with their 3in cutback as well?

Flashpro is the tuning solution from hondata. There is also ktuner which can be used. The engine has a single exhaust port, so people call it a downpipe. Numerous people have the ultimate racing setup. Nothing wrong with their setup.

q300 exhaust and 3" catted Downpipe is the way to go.

why q300? and why cat? i am currently not running a cat on my ep3.

 

[Michal006]

Q300 sounds deep and it's not raspy. Catted because no fuel smell and it won't give you raspy noise with exhaust.

a lot say the catless downpipes have a "hissing" sound, or they say it sounds like they have an exhaust leak on the 9th gens

appreciate all the heads up. i am looking at going with takeda intake and up in the air between q300 or ultimate racing exhaust
