Well, I'll be honest with you, I was happy with mine all around from the moment it went on, but Steve thinks he lost some bottom end and when he added his Magnaflow in addition to the Aero it came back.

WAIT ....

Now that I think about it it may have been the other way around. Maybe he lost it with the Magnaflow and got it back when he added the Aero ??

I can't remember. I think it's people who not only add the Aero but also go up a size or two in their exhaust that loose a lot of bottom end. It's been mentioned before and I think it's true .. you CAN go too big when it comes to exhaust. Apparently the exhaust gas just sits ther and doesn't flow well if you go too big.
