Default Re: Does the OBX Catback Drone?

If I could figure out how to post a video I have one on the dyno. It is much deeper sounding then the Corsa. I had a Corsa on the GS with the 396, longtubes and no cats. It was too loud and barely passed the noise limit at Englishtown,

Dominic, I think this was one of the earlier runs before leaning it out a bit, But no I have no noticed any oil usage at this time.

Rich,

Can you hear differences in Drone level between the 2?

Jeff, I don't notice any drone. I was really surprised how quiet is is and that there is no drone. Maybe the fake cats that look like mini glasspacks on the headers quiet it down a little before it hits the mufflers? I'm sure it gives up a few HP compared to the Corsa or others, but for the price I'm fine with it. I paid under $900 for both (headers and catback)on sale last year on E-bay. The Power Effects that was on it when I bought it had terrible drone. That was with the stock manifolds and cats,

I now have the Magnaflow 3" system on the GS with longtubes and no cats. It has some drone and a mean growl to it, I have a 700R4 with 3.73 so the rpms are higher to keep it out of the annoying drone rpm most of the time.

I also have a magnaflow on the Lightning that sounds great with no drone. It has a very short exhaust with the side discharge out the passenger side just behind the door. Although my wife says its loud on her side when I'm driving.

It has a "H" pipe right after the resonator. If you look it up on Ebay you can see it. It is all 2 1/2" pipe.

I just purchased an OBX exhaust. I knew from this and other forums that the clamps wouldn't be quality. The 2.5" clamps don't come close to properly securing due to the lap joints, nor was a clamp included for the passenger side pipe to header. What 3rd party clamps did everyone purchase? Did you stick with band clamps or use lap joint clamps ?


Thanks

Lap joint clamps work best.
