R34 Stock Rear Muffler

[rgr34]

hi ppl had to put my stock rear muffler back on due to epa, as most would know its dual outlet from factory but ive noticed no exhaust gases coming out of 1 side, the right outlet, all exhaust gases seem to be going thru the left one...... is there a reason for this? is my muffler stuffed?

I think r34 adn some r33 zorst have a valve that opens at wide trottel to let gas go out the other outlet pipe. The r33 manual i have at home shows this on some skylines. I cant say for sure with r34 but i woul dbe guessing that is what it is. My 325 beema had the same thing too.

I have an R34 GTT with a nismo muffler (2 inlets and 1 large outlet) and on the top of one of the inlet pipes there is a motor thing that opens and closes the inlet pipe completely. There is a switch next to my xenon headlight hight adjustment (1 - 4) which says "sport" on one side and "silent" on the other which opens and closes 1 on the inlets. So mine is manual, not auto that runs off the throttle...

I imported my car from japan and it was already like this when it arrived here.

Hope this helps?

Thanks.

I am pretty sure that my muffler lets the exhaust out both pipes. Must be one of only 2 with the stock muffler still on the car lol
