The BMW 135i was an impressive machine when it was released. The upgrades BMW had made were noticeable, especially when it came to performance. With the release of the BMW 135i M Sport Package, the aftermarket world had a new challenge. How to make this seemingly flawless machine even better. After a lot time spent on research and development we were able to come up with a few modifications for this brilliant bimmer.

This customer bought his 135i with modifications in mind. He is far from done with his build, but what he’s added has already made his 135i relentless. Here are the modifications he’s done already,

• Jb4 and backend flash
• Dual cone intake
• Oil catch can
• Methonal injection
• 3″ catless Downpipes
• Agency power axle back
• Apex arc-8 wheels
• Michelin Supersport tires

Our Agency Power axle back exhaust and downpipes are some of the most popular mods we see for the 135i. The titanium tips of the Rear axle back exhaust look so nice with the body of the 135i and the sound is what you would expect for a high performance car. The downpipe is the perfect compliment to the exhaust. Between the two, you’re not just improving your sound, you’re drastically changing the effectiveness of your well aspirated machine.

We are excited to see what this customer does in the future. If you have a 135i you want to mod, shop all our 135i parts here.
