Had the exhaust and tune fitted 2 days ago. They too were very impressed with the quality of the headers/exhaust system.
The work and tune was done at a high end workshop using Evolve Technik. So far so good, loving the sound, much more purposeful now. I’m pleased I selected the resonator too. They're claiming 16kw/60nm in addition to the exhaust, which to me sounds ambitious, who knows? It definitely has a lot more punch from mid range to red line. I plan to get it on a dyno for an exact read to verify the claims.
Overall though I’m very pleased. Brings a new lease of life to my Clio.
