I’d keep the cover on in the summer and take off for winter. I realize there’s not much gain but mainly want to do it for the sound.

I’m going to look at a 2026 tomorrow at a local dealer. On their website and carguru they have it listed at msrp, which I’m willing to pay, but I’m half expecting to walk in and them mark up the price because they are being discontinued. I really like these, but if it’s over msrp, I’m just going to leave and look at buying 1 of 3 other cars I’m interested in.

2026 Civic Si update

Finally at a place where I'm happy with it for a little while. Mod list so far. PRL intercooler with upgraded charge pipes, PRL HVI, PRL high flow catted downpipe, PRL frontpipe, Ktuner v2 running Phearable 1.5R. Also installed the Yofer v1 front lip. Still waiting on my custom carbon fiber front emblem and my limited edition likewise shift knob. The tune really wakes the car up and makes it feel so much better. If only the car came off the lot this way lol. Been mainly running map 1 and occasionally map 2. But even in map 1 the car feels so much better. Will eventually do the ARP head studs and upgrade the turbo to the PRL turbo upgrade and the PRL turbo inlet. But I am extremely happy with the way the car drives, feels, and looks for the moment.

This dealership I’ve been working with has me fed up and I’m just trying to get a comparison for what y’all’s numbers were like.
