SLN Performance has been developing its own brand over the last 10 years, which focuses on the highest possible quality, without the usual "M tax" price tag
SLN Performance products are industry leading, being used by some of the most prestigious performance shops across the UK, EU and USA
We are particularly proud of our unique B58 OPF range, which was specifically designed to eliminate the highly restrictive nature of the OEM downpipe – thus creating optimal exhaust flow and drastically improving performance
Avoid cheap imitations!
