ok...i have been reading all these posts on a good exhaust for a while now but everytime i think i see somethin that i like, my A.D.D. kicks in full throttle. Here is what im thinking of....4-2-1 RK Sport header No Catalytic Converter Magnaflow resonator And a good muffler. I keep hearing that 2.25 is a good diameter for the piping but i have plans for a turbo...should i go with 2.5? Will that run me any problems or just a CEL. Im looking for anything to get me the most gains no matter the price. ANY suggestions or comments would help me out tremendously. Thanks!
run the Rk 4-2-1 header (if u wanna spend the $$, i think its worth it..)
then a brand name highflow cat
and the RK single catback, uses magnaflow muffler. same one i got fool!
costly yet fool proof setup...

1. get a catalytic converter.....stupid not to
2. if your going turbo...then WAIT on your exhaust...why would you buy a 450 dollar rksport 4--2-1 header just so you can throw it in the trash when you get your turbo?
first every state requires a cat, now if your like me and know a guy who knows a guy you could get away with it, but you'll throw codes unless you use a simulator, run 2.5 exhaust at least, less to upgrade later, BUY A CHEAP HEADER why spend big bucks on somethin your gonna throw away and only gain maybe 10hp max from? alot of these guys will preach about back pressure, personally i say flow it to death, 2.5 exhaust will give you a nice clear path out the back, your exhaust valves will give you all the backpressure you could ever want, the only engines i've ever seen that actually need backpressure are 2strokes since they rely on backpressure to help with fuel delivery. as an interesting side note has anyone ever seena turbocharged 2 stroke? sorry not post jacking just wondered, i saw a banshee with a small turbo mounted on it about 5 years ago.
J~
why waste the money on a header at all? smartest thing to do is wait on the exhaust if your gonna get a turbo
Get a Catalytic Converter. Not having one will not help you really in performance and it will just be plainly too loud for your own good.
If your planning on turboing your car soon, don't buy a header & get a 2 1/2" exhaust system to save from going through the process again. That being said, you can't buy a 2 1/2" cat-back system pre-made, you would have to get it custom made. Make sure you get it Mendral bent, not crush bent.

regardless of whether or not you are going turbo, put a catalytic converter on your car and you can get a turbo-back exhaust with a test pipe done later if you so choose.
I was a retard, and now I'm permanently banned.
no converter makes the exaust a lot louder?

OH YEAH!
It's like 2,000 bees chasing you. At one time my dual wasn't connected, so it was like I was running no mufflers. I used to deafin' people 8 blocks away HAHA.

i live in SC and we dont' have to have cat's!!! we dont have inspection.
we dont have to go through emissions in michigan either, but from the sound of it i guess i need a cat anyway. What if i just ran the 2.5 piping off the stock header until i got the turbo? would that be ok?
keep your stock exhaust, when you get a turbo get a 3 inch downpipe with an electric cutout at the end of the downpipe and keep the rest of the stock exhaust... ultimate sleep exhaust setup
my bubby has a build heads and cam forged storker motor LS1 on alot of direct port nitrous and he still uses his stock exhaust with a cutout on each header, its quite when you want it to be, it flows a ton when you want it to, its louder then all hell when you want it to be, it looks stock, and.... its cheap!
for a SC you should use 2.5 inch piping from the catback, however for a turbo you should be using 3 inch piping.

not from the catback...on the WHOLE exhaust...an exhaust only flows as well as its smallest part
