Hey guys i got an AP2 and i notice i get some droning with my test pipe, have any of you experienced this. My friend has got the same setup but his is an AP1 and i dont notice any drone when im in his car. Any comments or suggestions would be helpful!!

 

I notice some drone in low rpm high gear situations, i.e. climbing a hill with the a/c on in 5th gear at less than 40 mph or so. Where is yours?

 

Most exhausts are going to drone in certain situations, maybe it's the way you're driving? You can drive differently to prevent it.

 

you usually hear drone around 3-4K RPM i believe. my J's drones.

 

ya you will find a drone with most exhaust, having a test pipe probably doesn't help, as i noticed a big difference with my 70mm sparrow switching from cat to test-pipe

 

especially if you're going uphill.

 

thats where i notice the droning too! I guess its a choice between no drone or more power. I think im going to slap the tp back on though. thanks for the comments guys.
