I have a b5 s4 with a apr stealth cat-back. i was looking to upgrade my downpipes and cats.i was thinking about buying the apr downpipes but my car is automatic and i was told apr only makes downpipes for manual. i was wondering if anyone could suggest any good set of downpipes that would work for my car. i know i looked at 034motorsport and tey had a set that can be used for automatic i believe but i don't know if those are any good or not. any suggestions or advice is appriciated thank you

 

can go wrong with gutting your pre cats on your stock down pipes and making piggie pipes
