V35 Gt-8 Rear Muffler

[rx3ip]

When we put the car on the hoist for oil change , we noticed that one of the exhaust pipe is clean ..

I get one of the muffler shop to cut open the top of the muffler to have a look inside and found out that one of the pipe is blocked off , only there for show .. I asked them to cut the leading pipe inside the muffler and cut open the partitions to the second pipe and now both exhaust pipes works ... this gives me a couple of things ..

fisrt - it excellerates much better , either down low or mid range and revs freer to 6000rpm .. second - it sounds awesome once it hits 5000rpm and yet when cruise it is still very quiet ... thought share this experience

hey thats great advice man...i just got a GT-8 so i can't wait to get that checked out...thats mad

actually there is a spring loaded mechanism inside that opens when enough exhaust gas can push it open. yours may never have worked, or was rusted shut.

if you want a bigger sound, just change the whole exhaust!

Can you take some photos of the inside piping im intrested aswell?

FYI the main resonator under the middle of the car people in the states reckon to swap to the coupe mid muffler... i now own a late model stagea which im pretty sure has a very similar middle muffler setup to the coupe and 350z.... i cant see any reason to change to that pos the piping is actually smaller than the gt8 although the gt8 muffler is enormous so it probably cancels out in the end.

ill show you a diagram of the two stages of the rear muffler. have to do it later when i get home
