i just bought the HKS hi-power exhaust for my coupe 6MT and i was wondering if anybody knows the purpose of the two cans that connect to the rear mufflers (circled in picture)

there's a lot of BS posts in this thread, but dig through them and you may find the answer to your question.

you're lucky it's only three pages. i think the answer can be found on page one, though.

 

They're Sound Resonators.

 

will it reduce power if i remove them ?

 

im not a fan of that sound myself i dont run resonators on any of my cars or on my gixxer because i like to hear the pop on the overrun

 

so then you bought hks because? sorry, just trying to understand.

and resonators don't effectively affect performance so much as they do sound.

those resonators are there to help baffle the sound. any exhaust louder than 95dB is illegal in CA, and hks is already louder than that if i'm not mistaken (not by much). removing those resonators may cause a loud/raspy exhaust.

 

because i got it for 20% off because it was a return and had a few scratches on the center mufflers

 

lol good reason to get an exhaust that doesnt sound good to you.

 

well its true i do learn something new everyday

 

^^what'd you learn yesterday?

 

if you plan to cut them off, i'll take them from you let me know.

 

I learned that smoking cigarettes increase your heart rate which increases your metabolism

 

Solution . . . Sell your HKS set-up and buy a new exhaust which you like.

 

^ good idea but too much hassle im just gonna cut them off and sell them on ebay

 

Way to go with the choice to hack up a $1400 exhaust to make it worse . Even with 20% off, you still spent right around $1k for it.
