Resonator Delete plus Quads on Stock 440i exhaust

FirstBMWLA · 08-09-2019, 10:07 PM

Basically decided from seeing many videos I wanna go with the dual resonator Delete.
I'd like to also swap stock tips to a quad setup and get a mperf style diffuser.
What size are stock tips inlets etc?
Recommendation for tips? eBay? is Cyba still around the forums?
Anyone running this setup? Advice/tips?
Thanks!

Thanks, but I want to retain mufflers. straight pipe way too aggressive for my tastes.

If you figure this out, please let me know because I've been looking into this for a year now. There are quad diffusers out there, but I have not been able to find any quad exhaust tips for the 340/440 platform. I was thinking about getting it fabbed, but don't really know who to go to or how much that would cost. I think it would really make the back end of these cars.

FYI, I'm pretty sure the exhaust inlets are 67mm.

Maybe something like this?
just unsure if it's too wide to fit through a quad diffuser.
I know someone has done this... lol

Wednesday my car goes in for a 3 inch straight pipe to the mpe muffler. has a catless downpipe and electric cutout. This easy i can retain a quiet car in the neighbor hood and then on the weekend and fun runs and drag racing i open the cutout for maximum annoyance.

neonnblack · 08-10-2019, 06:07 PM

And any race shop or good exhaust shop can bang it out in less than a day for a few hundred. Mine quoted me about 250 out the door. Including integrating the flange for the cutout.

Anyone have specifics on quad tips they've used for stock exhaust?

FirstBMWLA · 08-30-2019, 02:49 PM

Alright.
project complete.
I love it!

Superb job. What tips and diffuser did you finally select?

drivef30 · 08-30-2019, 08:20 PM

^^^ what diffuser is that? Is it real carbon?

eBay diffuser. seller yctuning. It's not carbon.
I can dig up a link if you want it. Only 125 shipped and fit without issue.
It's gloss black. car is carbon black so going gloss black with all accents.
Tips are fake Akrapovic from AliExpress.

Can you share as many details as possible? Been wanting to do this for a while now. What’s the opening width on the diffuser for each side of the exhaust? I need to know what size the opening is so I can figure out which set of dual tips to use? Was this fabricated? If so how much was it? I want to run quad M performance tips but want to make sure they’ll fit in the diffuser’s opening. Also, do the tips expand in towards the center or out towards the sides from the original?

Any details you could provide would be helpful! Thanks!

I have a dinan midpipe so basically a pipe with no resonator. And I personally dislike the sound of my car now matched with a catless dp.
