Fit perfect!
Other then removing the retarded converter that’s right off the manifold this was an easy install. Sure I broke a bolt and accidentally hit myself in the face but that’s all on me. Also had to remove the metal strap where the downpipe meets the rest of the exhaust because it’ll hit it and make noise.

Ordered the Tsudo Downpipe/Header and received it in less than a week! Zero issues so far with my Kraftwerks 9th Gen Si!
