Legamax Premium mufflers are constructed of SUS304 grade stainless steel to give a high lustre finish which is durable. HKS Legamax Premium Exhaust System. 100% Authentic HKS Product.
I got it installed on a 2018 USDM WRX STI. This exhaust exceeds OEM quality in terms of construction and hardware. A little heavier than stock due to its higher quality polished stainless steel construction. It fits all OEM hangers and OEM down pipe. It’s not a loud exhaust but it does add more bass to the exhaust note, bringing out the EJ rumble. Bass sounds are louder under 3000 RPM from inside the cabin. It fills in the exhaust cutouts very well. I recommend this product if you are looking to bring out the rumble sound and reduce flow restrictions while not being obnoxiously load and not requiring a tune.
