Please help me decide
Options; 2nd cat del.
C63 mufflers
E63 mufflers
Gut stock mufflers
Cut-outs, or some combination of the above
My head's spinning and my eyes are glazed over!
I need the voice of knowledge and experience to hopefully guide me to a decision.
As for performance what to consider now that I have 168 pulley/header/tune?
I would greatly appreciate your input, especially from those who have knowledge and experience with the aforementioned. Watching 50 more video clips isn't gonna help me decide. I'm looking for 1st hand information please.
I know by now there's a decade's worth of real world information so please help. Thanks!

As for next mods, I would advise on upgraded cooling without a doubt. Water meth would be my go to, if you aren't game for that, then upgraded HX, pump, and FTP underhood tank with split cooling would be my recommendation.

They do a good bit of silencing themselves.
Regardless your exhaust choice...cooling mods please.

It was not by choice it, was by force of auction =wallet

It is F*ing loud, I was in 2nd with my son in the car filming, I don't think I went over 4K... it is a state road that is part of a 6 hour two wheel loop I love, great get out of the city ride... state road, unmarked 50mph or 55 in NC I think I went 60 maybe 2x.
I will be adding more to break it up when I have time to weld in the vbands for the the x instead of the resonator. I also have 2 magnaflow resonators, that will go in. Then rear cans maybe depending how loud it is after the X and 3" resonators are in. There is drone, not bad though. You cannot pass someone while on the phone and I feel like a 25yr old ricer,/nascar driver. But it keeps me off the R1 and gives me a similar feeling; which was my purchase point.
sigh... It has been growing on me though

Have a sound or video clip you can share?
MBH Headers, Primary cat delete, Stock secondaries, Stock resonator and modified stock mufflers
Anyone selling E55 cans lol? I start to act like a Nascar driver with this thing the way it sounds

Magnaflow cans:

I guess you could call them 6x18" round "mufflers" but this is more of a resonator in my mind bc it lacks baffles... tomato/potato kinda thing I guess.

It does sound good but it just screams, quick mr officer he is that way... drive that general direction. He will hit is again.
Thanks for the compliment! Under Construction
HammerDown's setup sounds absolutely BasA$$ and classy, but I want a little tiny bit more BTFO sound. I think cut 2nd cats and your ears and K2 will benefit. Your stock cans do a great job keeping it classy. I would like a mix between HDs and my lack of exhaust.

Awesome, thanks. Nice low growl. I think I want a little louder, but maybe the sound doesn't really come thru on video. What do you think? Would you say it's noticeably louder in person then in the clip? Are your mufflers fully gutted? What's the difference in our headers?

Anyone with QTP cut outs? Is it possible to install them after the headers on the down pipe? or somewhere else before 2nd cats? I've only seen them installed behind the mufflers.
