Highly recommend the Fabspeed Sport Cat Downpipe. HJS is arguably one of the best catalytic converters. Wagner Catted downpipe is also guaranteed to be CEL free.

Appreciate all the help and sorry for jacking the thread with all these questions.
The raw ingredients that go in to a high quality catalytic converter are incredibly expensive so as a gross generalisation, the more expensive the cat, the better it's functionality.

My commute home yesterday. 1 Mile, 22 minutes. I don't exactly need the extra power.

Any chance you have a sound clip of this?

I just installed my Fabspeed sport cat and cant say enough about the sound and performance. I have it paired with a Dinan intake and BMS stage 1 and it seems to be working really well for the short amount of time I got to drive it today. Does anyone know if the sport cat has a break in/burn in period, And how long that might be? Also does the computer instantly adjust for the new air flow from the high flow cat and dial in the air/fuel or does this happen over a certain period of time? Also has anyone data logged a similar setup? Just wondering what I should expect for boost numbers etc? Want to make sure everything is where it should be.

Hello Tcmcec,
There will be a short break in period but not very long before the car is running smoother. (25-50 miles). Please give me a shout if it is still not running correctly. You have added a bunch of mods a long with the sport cat downpipe if it is still not performing the way you like I would love to talk to you about what is going on with your vehicle.

I will put the miles on and go from there. The only thing added yesterday was the sport cat. The rest has been on for a couple weeks.

I do somewhere. We hooked up a go pro near the exhaust to capture the sound. I’ll see if I can dig it up and post it somewhere.
