4" intake on RXPX, exhaust mods also?
I'm doing my Kanaflex on my RXPX, and this got me to thinking, I'm getting more air in, what about the exhaust? Should I get a Riva exhaust to get the increased flow out? Does anyone make a through hull exhaust without having to go with the Riva waterbox? I know on my old RXP I went from the waterbox straight out through the hull and eliminated the muller/silencer/flow restricter exhaust.

The Riva thru hull exhaust kit fits the RXP-X stock water box just fine.
You have to relocate the intercooler though.

I just added a homemade free flow pipe for $16. I dont think there is any performance gain between a free flow and rear exhaust. Rear sounds better, is more expensive and more involved.
I agree with you though. More air in means more air out and the X charger is sucking in a lot of air. It can only help and it sounds so much better than stock.

I wish i had my Stalker ATS system when i was modding my RXP so i could actually measure the gains for each modification installed.
I did some ATS testing on my FZR today after installing the Riva exhaust kit on it. The gains were substantial.
If any of you guys are curious about what I'm doing with my FZR this is the thread I'm documenting everything with

Mike, to run any of the exhausts on your RXP-X you will need to install the Riva intercooler upgrade kit so that it's relocated out of the way.
