Which is a better cat the techtonics tuning cat or one from random technology or is there one that is better but in the same price range?

 

my techtonics one made a good noticable difference. Random does Cat's for multiple cars where techtonics focuses more on Audi/VW. I would recommend techtonics if your deciding between those 2. you buying the downpipe as well?

 

No, not unless I need it

 

You don't unless you're going to upgrade your turbocharger.

Edit: You're also a tiptronic guy, so watch out; make sure if you get a downpipe it's tip-friendly.

 

well, if your getting the gtrs then you'll want the downpipe as well.

you'll want a minimum of 2.5" from the turbo-back.

 

techtonics has a solid reputation in the vw/audi scene so i would go with them.

 

With a K04 do I need a downpipe?

 

im running stock downpipe with my k04
