Res delete - Not X pipe

[vdubjetta02]

Hey gents,
I've owned a ton of really loud cars in my past (fully catless B6 S4's, Golf R, Porsche 996, SRT8's ect..) started a family and have a stage 2 B8 A4 right now and am starting to like my cars quiet, but touch louder than stock.

Right now I just have HFC, Mid res delete, stock mufflers and I love the little grumble but still being quiet for my kids


*I am looking into upgrading to a B8.5 S4 as the Avant is no where near as spacious as I was hoping and also bought an Atlas, so now I can just go back to a 4 door car. All I can find is the X pipe res delete and it is too raspy for me (atleast in videos)... Have any of you just deleted the large center resonator and replaced with straight pieces from a muffler shop, not an X pipe? My plan would be an intake, stage 1 tune and something to get a little more grunt from the exhaust. Worst case, I'll just slap some Borla mufflers in place of factory. I am done dealing with CO emissions, so I'm not even sure I'll go the pulley route as I've read a lot of you are ruining the cats which I am over dealing with. Just trying to find a car that I enjoy, passes emissions and makes a tad bit of noise. I have about 6 more months of enjoying my avant before I have to return it to stock again for emissions. At that point, I'll put it up for sale.

I think if you remove the center resonator (which is what the x pipe is utilized for regardless if your using it or not or is planning on using a generic one) itll have rasp. Resonators for me in any car is what always gave it a deep gurgle. I always just swapped the stock res for like a turbo one.

Check out the milltek race system. Even the non-res version has a centre resonator of sorts but it kills the rasp and makes the whole exhaust sound perfect IMO.

Thanks,
I love the sound of the engine, but I am not one for raspy sounding cars. I just want to find a cheap solution (since I'm done dealing with emissions) which may just be 2 Borla mufflers in replace of stock. I've done this before on another commuter audi I owned and enjoyed it.

my A4 the cheapest route was HFC and res- delete

I would encourage you to look at a muffler delete or saving the money you'd spend on the borlas to get a good high flow centre resonator, and go muffler-less and front resonator-less but keep a decent centre resonator. On these cars it makes a big difference in rasp and drone whereas the mufflers are purely just volume killing.

If you can smooth out the exhaust pulses in the S-Bend section you'll have no rasp.

If you can smooth out the exhaust pulses in the S-Bend section you'll have no rasp.I've just looked at it again and it actually has 2 centre "silencers" which I'm sure are fully x piped internally for pulse smoothing and scavenging. But no rear mufflers or resonators anywhere.

The bends in the midpipes are adjusted to mitigate the low end rasp and drone, and the rear mufflers are deleted. I bet you could get a good muffler shop to recreate this on the cheap, the flex pipes are also important in getting rid of any low end rasp so keep those.

They also use 2.37" OD pipe which is just normal 2" ID pipe to help maintain exhaust pressure for scavenging. Any bigger than that and you'll have rumble/rasp.

I would say an exhaust shop shouldn't charge more than a few hundred bucks to recreate this system provided you get good centre resonators somewhere. https://uploads.tapatalk-cdn.com/20190401/59878f0d3ac221811fc78a9aa0512f58.jpg

Dont delete the resonator and not use an x pipe. It will sound like $hit without one. Get this. https://www.ecstuning.com/b-ecs-parts/s4-30t-center-x-pipe-kit/003029ecs01kt/

From what I've read, the further forward you can put the xpipe, the better for drone. Start by removing the baby resonators at the front, and putting an xpipe there, leaving the rest of the exhaust in tact.

Fwiw, that's what I did here, but straight piped everything , so nothing but cats, dps, xpipe, straight pipe. You can imagine how this could sound with some nice mufflers at the end to quiet it all back down. I don't feel like I have any rasp, even without mufflers and a renter res.
