so what are you doing? are you like filling in the little slot on the bumper cover? or are you putting a muffler there just for the "look"?

Well I think we have bored this guy enough with the exhaust stuff. since he already has a cat-back just get the RB collected header and pre-silencer.

Well you can get some of these too:

Pineapple racing sleeves
polish/port your intake
loose weight
make some cold air ducts to feed your intake
get carbon fiber stuff like a hood
i saw way back some fenders made out of cf on ebay

Im filling in the cut out (or slot as you called it). Adding a muffler there would be ******* gay lol

Yeah so what are you using to fill it in?

Do you know of any people that have dyno numbers on the HP gain from the PR sleeves? I want to buy some for my car but don't know if it is going to be worth it.

I also agree on the single exit exhaust looks. The dual exit is like a trademark/birthmark of the 7 series (aka it's the only car with one...the others just have dual outlets on one muffler). As far as bang for you buck, I'd pick up the duals from mazdatrix and an nice filter (I use bonez) and make some piping for the intake. Take the plates out of the throttle body (of course not the back/primary plates ) which gives a very nice increase in responsiveness, get rid of the A/C (keep powersteering...no sports car should have a ratio higher than 2.8:1 ), make sure the auxilary ports work or get rid of them all together if you don't mind losing the low end (I mind very much), and port match the manifolds to the gaskets. There are more things you can do, but at least those things you can do w/very little fuss, and w/out taking the motor apart just yet. Good luck

Man I can't wait till this weekend I am tearing my spare engine apart with the help of "wankel7" hopefully and maybe "MAX-IMAL" Man this is so exciting.
all I need is the engine hoist and time

I wonder if I can learn to do a bridge port or J port?

Oh another "best bang for the buck" mod would be to find a parts car. You can use it as a test dummy for some custom mods on the parts from that car and you don't mess up your ****. plus you make a lot of money out of it.

I've heard that the PR sleeves are awesome. Never tried them myself tho.

Lets not get off base here. Carbon Fiber parts are by no way cheap and they do little for performance, so those are out. PA racing sleeves are cheap and are a good improvement to your 13B. If you have a base model, like me, getting an LSD off of an S4 GXL is a good idea. Ya can also port the throttle body elbow, but this probably wont do anything unless you have a ported motor.

what kinda gains do you get off sending your sleeves to PR???
