TT Surgeon - FYI, my hat is off to you for being able to take off an OEM exhaust without removing the rear bumper and intercoolers. After reading several threads here, I thought I would try it, but there just was no way for me to get it done even with the stubby ratchet. The shape of the OEM cats just wouldn't give enough space. However, after installing the Fabspeed exhaust, I am pretty sure I could remove it without taking off the bumper cover and intercoolers. Just my 2 cents.

 

If it's a major leak it should have triggered the CEL immediately.

 

All I can tell you is there were no codes thrown. That had me puzzled too. But, I just took it for a spin and I've got all the HP plus some!!

 

How much boost are you running?

 

I have a stock 07 Turbo, flashed ECU, and now exhaust. So, I'm not running an excessive amount of HP. I figure somewhere between 550 and 600.

 

Which pipe was it that came undone?

 

Driver's side lower hose.

 

do you have to take off the bumper to get to the intercooler hoses?

 

lower no upper yes.
