Install was quite simple, even as a first-timer doing mods. But the sound that it brings makes driving so much more enjoyable and engaging. The induction noises are crazy!
Smells amazing. Smell lasted me a couple weeks and even after the smell is gone still a nice cool piece to hang in the interior!
Did the 1b1 method at 30k, have been tuned ever since with tsp stage 1+ and no issues. At 140k now and the head gasket now needs to be replaced. Will replace and reinstall the arp head studs and will most likely go another 100k no issues. I drive my 2017 Si like it should be
Perfect for the Massachusetts winters! Especially with my hybrid racing competition shifter!
