R31 RB30e exhaust setup..

[Lumia]

Hello guys, first time poster here. I am looking to get a bit more noise out of my 31.

Previous owner fitted a GTS2 2.25" exhaust from catback after upgrading the exhaust in their GTS2. I want to get a bit more noise out of it, but also not insanely loud.

The current setup is like so: [Headers]======<CAT>======[Muffler]===========[Muffler/Tip]=

I was thinking of adding a Magnaflow rear muffler with dual tips on to the current system. https://i.ebayimg.com/images/g/0H0AAOSwrklVJVNc/s-l500.jpg

Or would it be better to do a centre muffler delete and replace the rear muffler with the Magnaflow.

Current rear tailpipe/muffler is like so:

It’s probably going to be trail and error to get what you want 

magnaflow rear and then delete Center if you want more noise would be a start. Then if too loud add a straight through middle muffler

Get a 2.25" cat back made up, like the GTS2 system but with a "turbo" mid muffler and your choice of rear muffler.
Sell the GTS2 cat back.

Almost forgot about this thread, I ended up getting a 2.25" with a hi-flow cat, flow-through centre muffler and straight out to dual 3" tips.

Very happy with how it sounds, not too loud either
