FAQs
Which is better for the 435i/440i — decat or sports cat?

Decats offer maximum flow; sports cats retain road compliance while still improving power.

Yes — upgraded intercoolers help maintain consistent power.

What suspension upgrades improve handling most?

Springs and anti-roll bars give the biggest improvement for daily and spirited driving.
