Wow. Why did I wait so long? What a nice difference. Butt dyno says it feels better. Probably a nice combo with the Magnaflow cat that went in recently. I just ran up it past 150 km/h and it was just pulling smooth and strong. Brand new Purolator Pure One air filter in there, which is supposed to flow a bit better than a standard paper. Wonder what a K&N would do? Probably makes more sense to just do the K&N with a CAI tho.
As far as sound, no complaints. Haven't tried it on a cold morning start yet, but after sitting in the driveway for 2 hours with the hood up, it didn't sound bad at all on start up. Even at wide open throttle it did not sound too loud. If anything, it could have been a bit louder. Wonder if the 98 just has more sound insulation?
Two thumbs up for this mod!
