You won't "feel" any difference with exhaust and or intake. You will hear the difference and feel the growl which is very nice.

Short of nitros or FI you won't ever bolt anything on your car that will make you feel big HP gains, because there's nothing short of those that will give you big HP gains.

There's a chance you'll lose some horsepower without proper turning

When I was turbo'd and went from 2.5in exhaust with CAT, to 3in exhaust w/o CAT, the difference literally felt like I gained 40-50whp. N/A....can't feel crap.

Even if you did CAI, hi-flow cat, cat back exhaust, pulley, computer re-flash, you would be lucky if you felt it (maybe a bit more on the top end). Butt dynoes are notoriously inaccurate.

I did SR motorsports pulleys, RP mid-pipe with cat, and Greddy cat back at the same time. Didn't "feel" any faster...

The RB flash was plug'n'play, and definitely noticeable for me.

Never felt a difference from cat-back or the RB ram duct.

lol. I bet you a million dollars no intake and catless midpipe will feel even remotely close to 80 whp on the rx8.

If you were in FL, I'd turn down my boost level and show you what 80 feels like.

Dude, my ButtDyno® is fully calibrated. I put on a Type-R sticker and I also felt a +20whp gain. It's working properly!
