Hey guys,

Due to stupid police, I'm swapping my cat-back for the original OEM GTR cat-back. I know I will be loosing some power and agressive sound with the OEM cat-back.

What can I swap/upgrade to my setup to get back my lost power and sound? I'm thinking about getting a GLUTTED cat.
Anything else?

Thanks!

My mechanician told me about an electric valve with a Y piping, when on the track could help my performance. what do you think? is it worth 300$ ?

Why do you have to swap it back. If it is due to noise levels then there are many ways of getting around this without loosing the exhaust.

Just get a decent exhaust with 2 boxes instead off one. They aren't that loud at all and don't loose massive horsepower like the stocker!
I have an exhaust like your RSR and took it back off in 2 days due to it being to f*cking loud! :chairshot
Just get something else and you'll be fine for the boys in blue ;)

Okay the problem in canada is that we can't swap an exhaust component that don't respect the OEM spec. 95% of the cars made are not STRAIGHT-PIPE ( or free-flow). There's so many sh*tvic out there with aftermarket racing exhaust that any police officer use a tape to measure how long his tape goes into the exhaust before hitting something. So, if his tape goes throught the whole cat-back, he will think i'm not legal because it's not normal to be straight-pipe.

I KNOW the OEM BNR cat-back is straight-pipe but these morons can't understand this fact. this is why I want to swap it for a OEM.

Sound/DB is also an issue but police officer don't have dm meter in their car to measure how loud is my GTR, so I don't care about sound because I know it's impossible to get a ticket for DB because they can't prove it.
