Will this downpipe fit my G87 M2 / G80 M3 / G82 M4?
Yes, this downpipe is designed specifically for S58-powered G87 M2, G80 M3, and G82 M4 models and uses factory mounting points for direct bolt-on fitment.

Is this catted downpipe street-legal?
The 200-cell catalytic converter maintains emissions compliance in most regions, but regulations vary. Check your local laws before installation—contact Project Styling if you need guidance.

Can I install this myself?
If you have exhaust experience, yes—it's a bolt-on part. For peace of mind, professional fitting is recommended, and a service is available in Southend-on-Sea.

What performance gains should I expect?
With a tune, typical gains are 20–40 hp and 30–50 lb-ft torque. Untuned, you'll notice sharper throttle response and quicker turbo spool due to reduced backpressure.
