Just installed my joeZ axle-back exhaust. Either the exhaust is very loud or i didnt install it right. under 3000 rpm it feels very deep and loud.

When cruising on the hwy at around 100-115 km/h it seems to drone. only when you let off the gas pedal the sound goes away.

When car is parked it rumbles slightly? is this normal? or did i install it wrong? but it seemed very straight forward, had a professional shop do it.

 

Likely normal. Full catbacks are usually a bit dramatic at first, then you get used to it.

I did an axle back and normally, it's about perfect for a car that's a mix of luxury and sport.

 

Thats why I chose f sport exhaust. Perfect loudness.

 

I think it's normal. The JoeZ has a really deep sound which I like under 3,000 RPM. Did you remove your resonators by any chance?

Are you sure it's actually drone or just the exhaust note? The drone I had before putting in aftermarket resonators was deafening and basically caused everything in the cabin to vibrate and shake.

 

I have the axle back alone and I have no drone at all and under 3k i can barely even hear that thing...the cat-back I know is deep but if u have axle you shouldn't really hear much to where it's noticeable....check the screw and make sure there's no leak

 

Anybody delete the 2nd cat with the Joe Z axle back? I'm thinking about doing this. Just wondering what it'll sound like.

So it would be primary cat - delete 2nd cat - stock resonator - Joe Z axle back.

 

It's been done....the res delete

I believe there is also you tube videos of this too
