Dinan S1 M2 Comes With Moderate Upgrades

Dinan is probably the most famous BMW tuner in the U.S. They have always been all about performance, so their Dinan S1 M2 is about to become universally loved.

They still haven’t unveiled all the upgrades they are preparing, but some of them are known. For example, the engine upgrade will bring 31 extra HP to the table and 31 more lb-ft of torque as well. Dinan claims that, though the numbers don’t seem like a lot, the change will be obvious.

They will also instal new carbon fiber high flow air intake, created with lightweight materials. It will impact the sound, which will become more aggressive.

The new exhaust will come too. It will be made of 100% 304 grade stainless steel and also bring a slight power increase.
