OK MY QUESTION IS WHAT WOULD GIVE ME MORE POWER. IM RUNNING RACE HEADERS SHORT RAM INTAKE REFLASH AND HKS POWER EXHAUST, I WAS THINKING IF I PUT BACK THE STOCK EXHAUST WOULD IT FEEL DIFFERENT IN POWER WISE?

 

kpro and a tune

 

cuz i use to have downpipe with shirty headers then i purchase some racing headers after a while the check engine pop up so i knew it was the header sensor so i been unpluging the battery off and on so it would go away, cuz for some reason i felt my car run stronger with the other setup maybe i just need kpro and the tune.?

 

if you get kpro and get your car tuned, you will see the difference, kpro will also get rid of the o2 CEL popping up, that or defouler

 

stop typing in all caps please. it's really annoying.

 

You must have a si. If you do, the reflash is just plug and play. If youre putting the stock exhaust back on your gonna feel a difference. K's like to breath so the bigger diameter in the exhaust the faster your car goes.

 

The mufflers that come stock on the RSX/EP3 are pretty free-flowing. The OEM B-pipe is where the restriction is. Buy a 05-06 RSX-S B-pipe. Be powerful and silent.

It still amazes me why folks replace perfectly good OEM parts with aftermarket crap that doesn't do anything for power.

And yes. stop typing in all caps. That's a good way to get your post locked.

 

with stock engine and stock ecu i reached 212bhp only with an invidia exhaust

 

i got and 04 rsx and i told my homie with a 06 type s to test it to switch his exhaust for mine and test drive,, so having a 05-06 oem parts on my car it would be more powerful? i didnt knew that thanks

 

just the b section exhaust because it is larger diameter.

Incase you dont know
A=Exhaust Manifold(Header)
B=Mid section exhaust
C=Muffler
