This is why SPD Performance created these SPD Exhaust Adapters - see below...
So you wonder - what the heck is this?
If you see below, the SPD adapter is on the left and the OEM adapter is on the right...
These larger adapters will maximize flow, greatly reduce exhaust back-pressure and help to lower Exhaust Gas Temperatures (EGTs).
The outlet is 2.3125" ID compared to the stock outlet which is 2.0625" ID.
This is a 25% increase in area for the exhaust to leave the turbo...
You'll need a stud puller - well worth the $20 to save your knuckles!
The guys at the garage had all the right tools to install these puppies... thank God!
They seem to be doing the job - the exhaust sounds a little deeper too!
