Do you have a sound clip you can share?

have a look at my MBRP thread, first few pages have videos

MBRP Exhaust

Warning......last few pages are full of BS!

Shades - can you take a picture looking inside the tips, want to see how far the pipes come out? Also, do you think finishing your project off with exhaust wraps might get rid of even more drone?

maybe this can help you... buried in the thread

That does help, but that's not shades car. Really want to see how far his pipes extend since he reported that drone was almost gone. But thanx for the link!!

Maybe try to be constructive to the discussion and dont bring this thread down too with garbage posts like this.

@white03 are you looking for shades set up with the aftermarket tips or just the pipe extensions into the valence? If it's the latter I might have some measurements for you. Cant help with the former because I am not yet running aftermarket tips.

You are like the plague following me around. Could you stop please! As like most of us I’m not interest in playing your bullshit banter game.

Hope this helps some. I don't think it really matters how the pipes extend with the tips though..it's different than just having the tips extend inside the stock chrome faux tips. These actually attach with clamps to the pipes so it's not like they are just sitting inside like with the stock ones. Make sense? The drone mainly came from the reverberation of exhaust bouncing inside the stock tips and then back to the undercarriage..not to mention the added road noise due to not having mufflers under there or the little baffle plates that are on the end of the stock mufflers.

Side note: After extensive driving to work and back today (120 miles), there is still a mild drone..NOTHING like before though. It is more when you are first getting on freeway or initial take off from light..depends on how heavy footed you are as well..my opinion..but once at cruising speed, its not bad at all..once you turn the volume to 2, it pretty much goes away. May still do some dynamat just to try to quiet it a hair more..but my wife likes it the way it is, so that's saying a lot!

Forgot to attach this as well. Let me know if you want other pics. I'll see what I can do.

"I don't think it really matters how the pipes extend with the tips though..it's different than just having the tips extend inside the stock chrome faux tips" "@white03 are you looking for shades set up with the aftermarket tips or just the pipe extensions into the valence?"

Yes Shade that does make sense, thank you

I've been contemplating axleback exchange with new tips, but don't want any drone (seems this should be achievable), so I've been reading every exhaust post trying to learn from what others did and what their results were. Seems I read a couple posts where guys said extending the pipes well into the tips greatly reduced drone (I think that's what Shade did). Another one, and I think it was a Tork youtube, that said adding exhaust wrap to close the open gap between the pipes and the extensions (tips) helped a lot. So I am trying to piece together what I need to do to eliminate drone??

Guess I'll keeping reading until someone figures it out.

Shade- thank you for the additional picture. I see your pipe attached solidly to the tips, there is not a "gap" between them. Don't see how there's any "bounce-back". Wish someone smarter than me about this stuff could figure out what components and procedures are needed to eliminate drone

Even though the exhaust is now fully leaving and extending past the valence, just my opinion, but I think being that it is now straight piped, with nothing reducing the exhaust note or back pressure like the stock mufflers did, there may be some sound just coming from the pipes themselves. I have also thought about wrapping one side to see if that is in fact the issue. I have some titanium heat wrap so I may try this weekend and see what happens. Just not sure if I will like the look.

I lined my trunk with Noico mat and liner before trying the tips. It’s the same material as Dynamat and Dynaliner, but at a fraction of the cost. Got it on amazon. It made a noticeable but small difference, however the tips themselves helped the most. With them both, I’m really happy with where the tone ended up.

I’m not sure you’re going to find a “zero drone” solution.
The “drone” really depends on your preferences and sensitivity to sound level. If you want to guarantee zero drone, then stick with the stock exhaust. Maybe try one of the quieter exhaust systems with tips for best results - someone had a comparison thread up previously, just search.
Gotta ask why you’re looking for a sport exhaust upgrade if you don’t want to hear it? Even the stock Challenger R/T I’ve rented had a noticeable exhaust tone on the highway, but that’s part of the car’s character.

I want to hear the exhaust, but believe that can be done without causing drone reverberations.

But maybe I'm wrong? I'm new to this sports car thing, been driving trucks for 30 plus years.

I personally like the way it sounds currently..the mild drone doesn't affect me...hell, I have to pick up customers in mine and even before I did the tips, everyone of them said "this thing sounds like it's fast"....gives me a great opportunity to break the ice if needed and step on the skinny pedal some!!

I think in in whites case, maybe, he wants the external sound and the overall WOT sound, but more of a stock sound inside. Which like you said, may be a little hard even with say wrap or dynamat and the tips...all personal preference I guess.. definitely agree, the tips have made a HUGE difference rather than just muffler delete and stock tips.... drone may also have something to do with the rear hangers..maybe some is traveling through and being that they are attached to the body, that amplifies some how.. hmmmmm...NEW TEST!!

Haha, I feel ya man...I've been driving trucks or a jeep for the last 15yrs or so...last semi sporty car was a VW GLI that I did a ton of work to...but even it didnt drone..maybe becaise it was turbo back, stage 3!! Lol

We have to be able to find a damn happy medium somewhere!! Keep ya posted on the things I'm gonna try this weekend!!

It's hard to say because some of that comes down to what's personally annoying to you. I dont believe there is a set up out there that will 100% eliminate drone using just exhaust configuration though. Part of that comes down to the design of the body, with the trunk area being open to the rest of the cabin. It is a pretty common characteristic with hatchbacks in general.
As was mentioned earlier, sound is also not exclusively coming out of the exhaust exit either. So while a tip set up could certainly help, it wont eliminate the problem completely.

A bit of masking tape, a bucks worth of barbecue paint to stock tips and looks the same as application day, a year and a half ago. No more dirty exhaust.

@SKStinger can you post a picture of your oval tips? Thanks
