So i got a hks downpipe and midpipe with apexi n1 dual canister.
i was wondering if i get the racing beat exhuast would tha tmake a differece or i need to change the hks downpipe. any advice on who got this set up?

 

WHat difference are you talking about? Do you mean noise? If so I do believe that the Apex'i N1 dual is one of the loudest catbacks there is for the FD. I would say the RB should make a significant difference. Also you may want to think about a resonated midpipe. No need to worry about the DP.

 

You may also want to search for more information on running a mid-pipe and whether that is an appropriate modifications for you. Key term is "Boost Creep", it's cause and affect.

 

I have the exact same setup; well that and a resonated MP. Your car is loud as hell, I know becuase mine was with a stright MP. Changing to a large resonated MP really quited down my exhaust, thank God.

Most people are going to tell you to get the RB exhaust because most seem not to like the sound of the Apexi N1 duals. I'm going to be different than what i know the crowd will say and suggest geting a resonated MP. Personally, I love the sound of the Apexi duals....correction, i love it with a large resonated MP. without it, it sounds terrible and is stupid loud.
