so i've seen lots of dyno graphs on 262 and 272 but i want to know what they sound like actually on an EVO with upgraded exhaust. can anyone give me a sound clip????
-A

of the compairison? i have a clip of the 272s

i want to hear as well

I am also curious as to how much the exhaust note changes with a cam install. I am going HKS 264 for intake and exhaust. Can someone chime in and give any feedback as to how it altered the sound?

264 sounds basically stock

Barely louder at idle with slight hint of lumpyness here and there. This is on my car with a tp and pruven axle back. BTW, 264's rock!

to dilute all the hype on 272 cams

On my 98 GSX, I went from stock cams to straight 272s and the exhaust note was noticeably aggressive and louder across all rpms. WOT sounded much better, especially when the wastegate opened up.

does it sound more High pitch at higher rpm?

I would say it sounds more raspy. It could be different on the EVO though and w/ 264s.

to me it sounds much meaner and deaper somehow.. like there's an extra cylinder in there or something! (272's that is.. i don't know about 264's)...
