Talking Agency Power Valvetronic Exhaust...Video Attached

Guys, I couldn't resist. Totally insane...

This thing completely changes the car...crappy quality video and probably way too close to the exhaust for an accurate sample to be recorded.

Only have about 40 miles on it as of now but once break-in is done, I will be shooting some go-pro footage...

Dan at Vivid Racing was outstanding....their service and beautiful product spoke volumes...no problems on install, perfect fitment.

Cheers!

Chris

Sorry, I have an idea of what drone is, but not exactly sure...

Could you educate me on what that actually means? Then I might be able to answer your question more accurately.

Thanks!

Its kinda hard to explain but its a very annoying bass like sound that's generally heard at a certain RPM inside the cabin. Mainly at low rpms or cruising on the fwy.

I mean, it's definitely loud at low RPM's but there isn't anything annoying about it to be honest...really not sure what to listen for.

That being said, didn't have the opportunity to shoot film today so next opportunity will be wednesday - once I post that, maybe you'll be able to tell whether there is any or not.

Enjoyed is wrong - enjoying is more appropriate.

That being said, to say that I am enjoying this exhaust is an understatement...I am in love!

I'm waiting to digest what I already paid for this part but my inkling is that I won't be able to resist...

That being said, I'm worried that it will be too loud...especially with the rear already opened up...

Any thoughts?

It will be loud if the valves are open.
You should be fine with the valves closed.

True..that being said, when the exhaust is warm (after 15-20 of driving) closing the valves doesn't do much to dampen the noise at low RPMS (idle to 2,000 RPM).

After that, it makes a difference, but the tone is so low at low RPMS that I'm scared that I won't like it and will be stuck with a $2,500 piece of metallic artwork...

I will have to sleep on it.

I'm sure the mod bug won't let me sleep on it for too long. LOL

So overall for someone like myself that fears that an exhaust may be "too loud" What are your thoughts?

I know its quite loud now just stock...just not loud enough for me but almost. I also dont want it to sound like I have some crap exhaust on a normal C series. I love the stock sound but just dont want to take it over the top.

When the exhaust was designed it was meant for cars with headers. It is built to help quiet the cars with headers as they are very very loud.

Headers as most know are a big hp gain on the 63 motors and we wanted something to be able to have the car sound beastly but at the same time press a button and drop the car 20 decibels.

Honestly its a great product and i'm glad customers enjoy it.
