Couple of questions. 1. Are 200 cell sports cats much louder than stock cats? 2. Are stock cats the same between Euro and US models? Reason I ask is my dealer has lost my stock cats after fitting my resonated de-cat pipes. I've decided its too loud with the Tubi and want to go back. A couple of members here have stock US cats for sale. Dealer will pay for sports or stock cats. Any advice? Thanks.
1. They are a little louder but nowhere near de-cats. The sound is a lot "deeper". 2. Not 100% but the part numbers suggest they are different. I would get some decent 200 cell sports cats - they do improve the sound and allow the engine to rev up a little more freely.
Thanks Aldous, a little louder would be ok. Mmm...deeper, thats what I don't like about the resonated de-cat pipes. It's kinda lost it's zing. Everyone wants the high pitch F1 sound but removing the cats has made the sound deeper.
What's a good place to source Euro Spec Challenge Stradale Catalytic converter? Also does the ECU need to be adjusted with install?
