OK I have the following setup and not sure about a change that I am thinking of making.

Large street port engine
XS T-04S Single
Baffled mid-pipe
RE-Amemiya Dolphin backbox

The change would be replacing the RE-A Dolphin with a Racing Beat backbox.

The change is for noise reasons. I have just installed the baffled mid-pipe, and this has helped in my quest for lowing the amount of noise my car makes.

Now would changing to the RB unit cause any issues with power? I.E. how much power can the RB box handle? Can it handle more than the RE-A box?

Thanks

You will not lose any significant power and there's many guys running around at 400+ rwhp with the RB cat-back.

 

You probably wont notice a difference. Unless the pipe diameter is different.

 

600rwhp has been pushed out the RB
