Hi Guys.
This is Tommy.
Today here in S.Korea is national holiday for the election.


I just have my muffler job done yesterday thanks for the good advices from people here.

I filmed the short clip last night on the way back home. video clip is not so good but you can hear the sound.

I just remove the resonators inside the muffler box , replaced them with stainless straight pipe.
That's all I've done.

Sound is soooo nice as I heard from 'Dpark', one of the guys who's given me good advices.

I feel no drones at all but the sound changes after 4k rpm , too loud , too scream with the high pitch.make me hesitate put acc fully.
Luckily, in comfort mode, the sound is the same before the surgery.

I don't know how to upload the cilp.
Just please see the link for your reference.

And I'm being helped by the Stuart from Velocity think I can do the VAP tune(pulley & Flash) soon!!

And.what I really want to do next is changing P7 grill.
Can anybody help me in this regard?

 

jesus christ that sounds insane! awesome job! can you make a full video? with pulls inside the car and the pops from outside? i wonder how loud the pops are now!

 

I will try ,maybe , tomorrow? I will upload it soon!

Sound is really good but it depends. Anyway, I like it.tha't all man!

Sounds great! I went with the VAP valvetronic exhaust on my V6 mainly because I feel like it had a deeper sound. However, I have noticed a little bit of drone even with the valves closed. Taeuck, since you're saying there's no drone at all with your custom setup (OEM vacuum hoses too), I'm wondering if something is wrong with the valves or vacuum hose connections on my VAP install that creates drone. Hoping someone can comment.

 

I like my neighbors too much to run straight pipes.

 

I like some of mine, plus I like what little is left of my hearing

There's also an HOA martinet down the road I have to go past that would introduce grief to my life that I don't need. Not sure how it'll go when I get my 900SS with Termignonis back on the road. It sets off car alarms.

 

Hi Devmen.

Thanks for the reply.
I for sure can say that there is no drone , almost!

Expecially, when the valve is closed, it's the original active exhaust function as you know, it sound totally the same before the modification. meaning it's super quite of course when comparing the dynamic mode when the valve opens.

In dynamic mode, someone can feel that it's a drone but i'm sure that it's not a drone but just loud sound of exhaust. you know the difference.huh?

 

So the case I'm talking about is at highway speeds with the valves closed. To me, the loud sound of an exhaust as a consistent speed and low RPM is droning. Fortunately there's no drone at city speed.
