I don't rev mi nismo in neutral, but its normal for a 370z to limit revs at 5k on an unloaded engine to avoid causing damage

I did the washer mod last weekend with my BERK exhaust. Lots of drone and sounded like crap. Took the washers out immediately.

Yeah, if u have an aftermarket exhaust then there is no need for it in the first place

cause i rev it 2day for the 1st time and it stoped at 5k i thought 2 my self woah woah wtf is going on lol...

I wouldn't do it on an unloaded engine with 500miles on the clock, but thats just me

no no yeah i understand what ur sayn bro for right now im just babying the car...

:tup:

Geez ! I tried this noon to do this mod. Well it didn't go further than trying to unscrew the bolts ! I spray some w40 but I guess I didn't wait long enough because it was still stuck ! Did you guys who tried this had a hard time like me ?

I'm adding washers on my exhaust tomorrow ill add a vid on my YouTube...

Ima try it tommorrow...

use pb blaster.

Are you sure you are untightening the right bolts? The end that is facing the front are welded in place. The nut which is facing the back end is what you want to loosen. You will love the sound. 2 washers is what the Nismo should have sounded like from the factory. Still quiet on the inside for the highway till you get on it and nice throaty sound comes at ya. 3 washers and it gets louder and deeper and you won't hear the engine noises anymore, just exhaust. For long highway rides you're gonna hear constant exhaust note. 4 washers and it gets loud, you'll start to feel vibrations in the steering wheel and some things shaking a little bit but it sounds mean.... I did all this and thinking back now I should have kept it that way just for the adjustability. But I did a muffler delete and pretty happy with it, took a min to adjust with baffles and all but the washer mod on this car sounds pretty good. I've heard it on other cars and it just sounds like crap. Have fun.

I thought I could be stupid enough to not see a bolt facing front, but it was not the case, there is only one bolt that fits in a tool...

Tried this morning again, and same... I'm beginning to f**k up the bolts... Oh well, I guess I'll have to find a garage that has better tools than me to help me on the job, but noone will want to do this 30 seconds job. Parisian garages are not very helpful, they'll try to sell me a full exhaust instead or charge me 100 euros!

Thank you for your help anyway.

Ps: unscrewing is anti-clockwise right ? Just in case :-D
