I may be wrong, but most of the drone issues seem to be with the 6.0L rather than the LS3 ?
Daves8 did you end up getting the dpe zorst and are you happy with it?
Not yet....... am leaning toward either the Walkinshaw stepped catback, or the DPE 2.5.
not wanting drone, but also looking at logistics of having system posted then fitted, or a walkinshaw supplier fitting as this is included in cost
Got lucky and found a brand new Walkinshaw catback with tips for $1300 (about half price for what a Walkinshaw dealer will charge)
can’t wait to put it on!
Will that match up to your extractors or do you need to modify it?
Yes, I have the REX 4-1 by GM Motorsport, they finish in standard position
Post a vid when its done, I'm considering changing from my 3" Hurricane system to DPE/walkinshaw. I have a cam and the hurricane sounds good but I think my preference is the DPE.
I have a LS3 wagon.
It was the full DPE set up. Extractors all the way through.
It's the 3 inch stepped to 2.5 inch.
I don't hear drone on mine that's noticeable anyway.
It is a deep sound, and not loud on normal driving. Flog it and it's load yes, but all of them are.
If you can I would suggest taking a car with one on it for a drive. Then have the owner drive around with you maybe on the side of the road so you can hear what they sound like from that perspective also.
You tube clips don't do any exhaust sounds any justice to be honest
I personally like them and find it the best sounding one I have ever had. But I'm not into the loud raspy sounding ones, but everyone is different.
People have mentioned in earlier threads about the baffling coming loose and rattling. I have had this on two occasions now. Both fixed under warranty. They replaced the whole cat back section twice.
I was getting a rattle under soft load at about 1300 rpm.
As its the W pack, there was no issues with warranty not kicking in.
The second occasion the rattle returned, the shop actually had a full 3 inch one there and put it on my car as I was thinking about upgrading since a new one was needed anyway.
I found it a bit too loud and had some drone.
I had the Walkinshaw system fitted today....
I am not blown away at the sound, actually sound fairly similar to my manta. It is possibly a bit deeper, possibly some more note separation at certain rev ranges, however I feel like I have lost a lot of low end power, possibly due to less back pressure with the bigger cat pipes and front section (3 inch vs 2.5)
perhaps I need my tune touched up.
will wait 1000kms for the system to bed in to give full commentary, but I think it will be better than the manta
Spewin,chuck the manta back on
back pressure is a myth but yes the 2.5inch is better for low to mid range and the 3 inch better for mid to top end power n/a LS
what ever has changed I have a lot less low end. Maybe this flows better, and I need my tune updated.....
I have kept it..... if I don’t love the Walky after 1000kms I’ll put it back on and sell the Walky.
Im just having a dig mate,hope you get it sorted.
been keen to hear both systems idle and rev out.
Got a 3 inch Difillippo cat back on my 2016 SSVR yesterday at a certain Melbourne mod specialist, went for a drive along the great ocean road today, could not be happier with it. No drone, great sound but only one small downside, no more crackle.
Very happy overall, happy with the install, happy with the sound and if anything it is quieter at 100km/hr than the stock with the relay removed.
i have chosen to not tune or do anything else with the car as I’ve been there before and love the way it drives now. Just needed it to sound a little more like a V8 should.
Once it builds up a bit of carbon I'd say you'll get some crackle back.
That can also be manipulated in the tune
I am about to put my manta back on and sell the Walky / difilippo system, just prefer the manta note
Price? Although I'd love to hear it before I make the same mistake haha
