[Joe Harris]

Finally installed the replacement tips and they had 3 distinct affects that I've noticed on the sound and feel:

Hey Mfed - I just took delivery of a brand new 2020 Stinger GT1 - and it had the 'STILLEN GT400' performance pkg installed by the dealer - which includes the cat back exhaust. I love everything about the car and the Stillen pkg, except the dreadful drone-reverb when crusing on the hwy below 2000rpm. So my question, could you please let me know which exhaust tips you got to mitigate the drone/reverb?

Thanks

Any tips will work. The goal is to get the exhaust to exit near the edge of the bumper so that the sounds don't reverberate back into the undercarriage. A lot of members are buying clamp on tips on Ebay or Alibaba but that requires you to remove the fake unattached tips from your bumper. My local muffler shop just chopped off the short tail pipes off of my magnaflow and welded on longer pipes to get the effective results. The muffler shop didn't believe it would make a lot of difference, but it's night and day - no drone at all afterwards.

If you want to go with tips, you can minimize the amount of alteration required to the rear bumper. After a lot of back and forth in the Quicksilver thread we figured out going with 105mm ovals works perfectly, and you can match that to the inner diameter of whatever Stillen's pipes are. There's a couple different options online.

I've posted links to the tips I got in a few threads, and I thought this one too but... Just do a quick search and you'll find them.

I just had the Stillen catback exhaust installed a few days ago. The drone is horrible. Getting the factory exhaust put back on (which I kept thankfully).

Before you do, have you tried the recommended drone remedies for every exhaust, primarily installing properly fitted aftermarket tips?

No. I’m not going to throw good money after bad.

So you'd rather not just install some cheap tips to completely eliminate drone? Mind you, this is a problem with the design of the car, not any exhaust. They all do this. Maybe exhaust companies should throw tips in as part of the package (Borla has them as optional but they're stupidly overpriced) but if you want your car to sound better and have freer flow, this is pretty much a no-brainer.

Finally installed the replacement tips and they had 3 distinct affects that I've noticed on the sound and feel:

- completely eliminated the low-rpm low-load 'thrum' and minor reverb, gone
- sounds much better from outside the car - definitely more personality without being loud, but still can't capture it on video
- essentially equalized the in-cabin volume from idle to highway cruising speeds, and sounds great under hard acceleration (IMO) - there are no wildly louder or quieter spots or rpm ranges throughout the entire range.

That last bit is sort of where my problem lies, and why I'm more than likely getting rid of the exhaust. Before the tips the in-cab low-load volume was the problem with the SO - once past those areas the exhaust quieted down to just above stock levels. The tips have now equalized the volume from low to high rpm and cruising, so while it's not as loud or "intrusive" as the prior no-tip low-load sound it's now essentially the same volume during any driving situation (except hard accel), and most importantly it's louder now while cruising on the highway than without the tips, and she's...noticing. I think this exhaust with tips is good enough to leave the radio off and just enjoy it (I mean, it's no V8, but...) but in this case there's not going to be a workable compromise to the in-cab volume issue for her so...

Final thoughts - if you're looking for personality and punch without waking the neighbors the Stillen with tips is absolutely the ticket, no question. It's got a deeper, growlier tone than stock and the tips release it from hiding under the car with just the right amount of volume so there's no question you're running an aftermarket exhaust, but you're not bragging about it. If you're looking for borderline (or more) street racer or attention-getting sound this is not your huckleberry, but if you prefer to walk softly and carry a big stick grab yourself this setup and you won't need to sneak into those fancy parties anymore, you'll be invited.

What
tips did you choose?

I like mine just fine. For me it's just right amount of added 'personality' without bugging the neighbors, and maybe just placebo effect but my butt dyno says at the very least it allows the motor to rev a bit quicker and use a bit more of the power otherwise choked off by the more restrictive stock system. Easy install, good fit, looks great, 304 stainless, more (perceived) power and no obnoxious noise levels - it checked all my boxes with no black marks.

There is one problem with it though...the SO. She's not thrilled with minor thrum during low-power acceleration conditions, like going up a slight incline on the highway, or up steeper hills at low speed (like every single street where we live in San Francisco...) so I've got exhaust tips on order to try to combat that issue, and if they don't do the trick I'll need to get rid of it so...you may be able to get your hands on one at a discount if things shake out that way. I can keep you posted if you're still in the market, just let me know.

Do you know what size tips are on the end ? didn't know if they narrowed down at the tips looking to purchase tips before i order the exhaust.

I have the same set up too and the same issue. What exhaust tips did you get and what sizes?
