“PRL High Flow Catted Downpipe, great fit, no check engine light, can feel the power. Glad i went with PRL as i've seen mixed CEL check engine light reviews for other brands.”
“Ordered this for my 2020 Civic Si and I have to say it was delivered fast and I installed it same day. Let me tell you this does not disappoint. The sound of this paired with my awe track exhaust is amazing. It's made it so loud. Do not hesitate this is a amazing product best of it.. No Cel light! 10 out of 10”
“Fits like a glove and seems to improve spool! The exhaust is definitely louder and more raucous, and a bit deeper. Best of all, there is no check engine light for emissions! If you do get a CEL, ensure that your downstream O2 sensor isn't damaged or contaminated, and reseat the extension harness that the downpipe comes with and clear the code - you might not have it connected quite right to seat all the wire terminals.”
“Expensive but worth of money. I am 100% satisfied in this High Volume downpipe. It's better than the previous downpipe. I would Highly recommend this to my friends.”
“If you don't already have an upgraded downpipe and you don't want to deal with the smells of a catless exhaust, this is the one to get. The welds are excellent, and you won't even need a tune or other O2 CEL defeat method. If you live in a state with emissions testing, the pending EPA certification means you get to have high flow DP sound and performance shouldn't need to worry about passing. Tons of fun and still good for the environment. It is pricey, but you can eat your cake and have it, too.”
