Got a Reflash and cat-back...what next

I have the Works P2 93 Octane relash, and UR 2.5" cat-back exhaust. What should I do next for more power?? I don't need an MBC, and a filter system is no good with my P2 (from what I've read) so those are out.

How about on a budget of $300-$500. Looking for bang-for-the-buck. Let's here em!

Cams are too pricey for me.

I don't want coil-overs, and not looking for any general suspension or braking help.

down-pipe is a great power adder and it is around $300 bucks and easy to install.

cheap tires cheap wheels cheap brakes cheap suspension cheap car tires motorcycle race

I hate to ask for generic hp gains, but what's one to expect? Also, would it make the exhaust louder??

I have the 3inch turbo back ultimate racing with high flow cat and it is not that loud at all, I think the catback makes somewhere near 10-12whp and the full turboback which includes the downpipe makes about 25-28whp and belive me on the top of the rpm range it pulls much harder.

Downpipe and a hiflow cat would make your Evo exhale better. I recommend the Buschur downpipe since it is good quality and clears the factory lower tie bars.

The UR also clear everything, and from what I have heard on cars the Buschur is louder the the UR with RMR being the quietest.

What about the UR downpipe? It'd make more sense to me to stick with the same exhaust if I could...

Order a UR downpipe by tomorrow and its only $250. Even though you have a flash, a boost controller should help. The downpipe-boost controller combo will really help spool the turbo.

How would a boost controller help? I have a boost guage, and I can hold boost over 20 PSI all the way to 7500rpms... in every gear!

Can you hold boost over 21 psi, 22 psi, 23 psi, 24 psi, in every gear? If no then you need a boost controller - unless the P2 somehow prohibits it's function - unlike the DynoFlash.

According to my boost guage (which is mechanical), I usually hold right in the 21-22.5 in every gear, yes. I'm thinking a lot of it might have to do with the cold weather though.

Either way, I think that's plenty of boost. Don't want to push the cut-off point, I wanna stay in the safe zone.

What about a high-flow cat or test pipe??
