My '13 WK2 V6 sounds LOTS better now, all for less than $100!

Took it to my favorite exhaust-system shop, Mighty Muf'ler in Phoenix, to see what I might do to add a little character to the sound. From the outside, it's a very quiet car. From the inside, it's so quiet I can hardly tell the engine is running.

The owner thought that replacing the center muffler would be complicated (= expensive); he suggested we start by removing the rear muffler. (He thought it was so large, it wasn't just an antiresonator.)

Off it came, and I test-drove it. Sounded great as near as I could tell, so on went a replacement pipe and the same oval tip I've bought many of over the years.

It now sounds GREAT--the exhaust noise inside the car is just loud enough to be heard, and outside, too, it sounds wonderful.

Interestingly, this system won't let me use outside-hosted images, nor can I upload images to this site. See

...for pics.


$94! I'm VERY happy.

Oh yes--it does NOT drone!!!!!!!!!!!!!!!!

:D

Hi jeffrey, great find. Would it be possible to take and upload a video so we can see what it sounds like?

Any sound clip yet?

Although I really don't believe you can get a good V8 type rumble out of these v6's. But I'm hoping so.
No; sorry. I'll try to get my son to do that.

It definitely sounds like a V6 and NOT a V8.

In the summer of '03 I bought a new '04 Porsche Cayenne Turbo. I LOVED that 'car'; it was the finest vehicle I had ever owned, and with 1st-rear ratio of almost 5:1, a 2-speed t-case, a very versatile variable-ride-height air suspension, and an off-pavement package, it was HIGHLY effective off-pavement.

But it was quiet, sounding not at all like a high-performance 450HP V8. On each exhaust bank, it had a turbo and 2 cats. Both exhaust pipes dumped into a HUGE stainless-steel muffler behind the rear axle. So off to Mighty Muf'ler the Cayenne went, where, as a first attempt and to see and hear what the result would be, we removed the muffler and replaced it with a pair of straight pipes. (I have to get going very soon; will post pics this afternoon.) The result was the sounds of a high-performance V8 that made just enough noise to sound FABULOUS. My Cayenne was the envy of MANY Cayenne owners I ran into at the Porsche dealership and at Porsche Club meetings.

I just wish my JGC sounded like that, but it's a V6 and not a V8.

Oy, that 3.7 exhaust sounds burpy. Whatever works for you I guess.

I just added the Gibson axle back system to my 3.6 and it sounds much better than it did stock. Definitely doesn't sound like a Honda and it added just the right amount of noise to hear it at start up and under acceleration in the cabin. Nothing obnoxious.

(You can probably guess that you guys aren't going to get any sound examples from the OP, as this is thread is looong dead since the last post.)

Cost me $60 for the install. 15-20 minutes, out the door.

The sound is getting better every day and I'm already noticing the break-in with a bit deeper tone than when it was first installed. It also definitely feels like I'm getting better throttle response and flow, even though I wasn't expecting it. I'm looking forward to seeing how the mileage is affected after a month or so of testing it out.

I had my local exhaust shop install the Gibson on my 3.6 Overland for around $90. I've replied to a couple different threads on this topic, so forgive my repetitiveness. The sound is decent and is without drone. However, it will probably leave you wanting more. Noticeably better than stick though.

Yeah. The Gibson is a good price. The exhaust shop I went to suggested just replacing the muffler with performance brand. They even said that they'd install several and let me listen to each and then I could choose. Good service. So naturally I went ahead and ordered the Gibson. If I was going to do it again, I'd probably take the shop up on offer to try different mufflers. I think he told me around $125 installed, which is less than half the cost of a Gibson. In the big picture though, it's still a good bang for the buck.

That's ultimately why I got the Gibson system. It was too much of a risk getting the other cheaper options for a dual exhaust (Dynomax) and everything else was too expensive for that kind of mod, in my opinion.
