[ntsantos]

For some of you that have seen my thread on these Synapse No Drone Resonators, these things actually work! I decided to go another direction so have these up for sale. Includes the following:
- (2) Borla Pro XS 2.5" offset universal oval mufflers.
- (2) magnaflow 4" double rolled exhaust tips.
- (2) 2" mild steel Synapse Engineering No Drone resonators.
Includes (2) brand new dual outlet exhaust tips for those that have a quad exhaust.

All for $250 shipped ConUS

Purchased separately these would cost over $400.

Please don't ask me if this will fit your car. This was ask custom setup for my A7. All parts can be chopped up by your favorite muffler man to fit your needs.

So I mimicked your exhaust before you put it up for sale. The guy didn't have time to install no drone resonators. The drone is terrible between 1800 and 2400 rpm. Please tell me the synapse no drone will make this hideous drone go away.

I can't guarantee it but they will work. If I had to do it again, I would install the 18" long ones, but either at the center resonator, or at the baby resonators on the downpipes. I think when you install them closer to the engine, the better they work.

They way I had them, it made the deep deep bass go away at low rpms and when going uphill. I don't know if you have the same experience, but when in S mode or manual mode, car sounded just slightly louder than stock. Drone only occurred in D mode.

Yea mine is that really deep bass sound at low rpm. It sounds great at any rpm above or below. But Damn it's bad in that normal driving rpm range.
