found it. so berk race which is what I had the exhaust guy who did the muffler delete copy, bms downpipes which is same as vrsf and now resonators. it makes sense why our cars sound the same....
I also want to delete the resonator that goes to the axle-back. I figured if we can get the part number for the y pipe that comes with the PE muffler that would be the way to go.

I'd figure any part of the PE would be expensive haha

Going to go to my legitimate exhaust shop now and see if they can custom fab a non-resonated y-pipe that can replace that resonator.

probably but who knows. getting the y pipe made and welded in could be 200-300 bucks. I work at a custom hot rod shop and I asked the main fab tech about somewhere to get a pre made y pipe and he said he didn't know of any local to me but ill check ebay.

Sounds similar to my setup (except I'm N55)
BMS downpipe
2.5" midpipes with Magnaflow resonators (but in different position).
3" muffler delete.
Heaps of videos here
and a couple of crappy pics.

Just an FYI, the old cats you cut out are worth $50 - $75 each to a scrap yard.

Does that mean I can get 100-150 if I take my old N54 midpipe to scrap yard??

Yes, I have a friend who owns a shop and he gets that for every cat he scraps.

No its only the cat section or just the old cats because of the precious metals in them.

i got a shop to cut the 2 mid cats out yesterday and weld straight stainless in place. they charged me 75$ and insisted to keep the cats. honestly its loud at startup like the n55 but after 45 seconds it sounds no different. i also have matt schnell ceramic coated catless dps. i was hoping for a little more aggressive, might do the pe mod to the stock muffler i have on there now.

So they actually charged you about $200 to weld in that stainless pipe.
