Hey y’all, I’m thinking of going for a VRSF catless 4 1/2 inch down pipe for my 21 x3. But my question is, what’s the best/most reputable downpipe for these cars, and what sounds the best a 6,5 or a 4.5 inch? And how bad is the catless smell?
I’m thinking about canceling my warranty for my 2021 BMW X3M 40i the car currently has 19,000 miles, the warranty is exclusionary warranty offered through the dealer by roadvantage for four grand and continues for 8 years or 120,000 miles which ever comes first. My question is if it’s worth it to keep. I don’t plan on keeping this thing stock but I’ve heard these oil pumps are prone to failure and any thoughts?
