So I thought I would post up a FAQ custom exhaust system set up thread for anyone who is curious to know what set up could be pieced together that works and sounds great.
This install is on my LD9 (No EGR)
4-1 Pacesetter header Painted black - PT# 70-1278
2.4L OEM gasket
2.25" Pipe from header to tips
3" Collector with Flex tube
Magnaflow freeflow Cat universal fit PT#HM-99204
22" Magnaflow 4" dia resignator PT#10435
Dual Dynomax Super Turbo Mufflers PT#17747
Dual Camaro rectangular Tips PT#1607<-- Your preference on the tips.
I plan to post up a video if I can get a camera man... but trust be assured, this is a great set up combo.,.. or less I wouldnt be posting this lol.
This would also be a good opportunity for others to post what set up they have... that way people can get ideas when they're in the market for an upgrade.
Post away!
Simple rule: Choose your exhaust parts like you'd choose a carb: Based upon flow! Just follow this rule of thumb (2.2cfm@10.5in.hg. for every 1hp) and you won't go wrong.
Go beyond the "bolt-on".

3" vband connections
3" CTI tubing

3" from header to muffler
3" dynomax ultraflow round muffler for resonator
3" dynomax ultra flow oval muffler

29" louvered cherry bomb ---2.5" diam.
2.5" pipes all the way
Magnaflow high flo univeral Cat.
APEXI World sport 2 muffler
Beautiful at idle, super loud at WOT (partly cause of my sub frame hitting the downpipe)
Very nice. I love the look of it. It sounds pretty good. Little too high pitched for my liking when you get on it a bit, but i used to love that sound. >.> I got old. lol
Great vid! Sexy cavy! Awesome color man. nice job all around! **Thumbs Up**

Ebay canadian log manifold
38mm external wg with open dump
2.5" 409 ss downpipe
2.5" 12" long dynomax bullet muffler
3" CTI piping
3" dynomax super turbo
Im turbocharged soo of course the sound is deeper, but just wanted to note how quiet turbo style mufflers are. I replaced my megan cannon muffler with a dynomax super turbo, everything else the same and my exhaust is sooo much quieter now even 3" and catless. I have a 30" long 3" glasspack I was gona put in but done even think I need to anymore.
Also have a question, whats a good exhaust tip companies that arent too expensive? I know magnaflow has plenty of nice factory looking tips, but dont realy wana spend $70 or more for an exhaust tip. Id like something similar to a factory ls sport tip, or an actual stock ls sport tip if I can find one.

Thanks! Just got a nice vibrant polished ss tip for much cheaper than a magnaflow.

Very tame exhaust. Its not stock sounding but it isn't abusive on the ears. Just the way I like it. Very minimal drone at freeway speeds.

Glad I could help mike! 
Try running the glass-pack between where the cat was & the first bend by the rear axle,
then tell us how quiet it is!

Okay... Details you want? Then details you shall get!
Carbs are rated not by diameter of their bores (Or area) but by amount of air they flow in CFM (Cubic-feet per minute). That is how the decision on what size carb to go with on a given application is made. After all, you don't want to be holding-back on the amount of air the engine that's been built can breathe, do you? Nor do you wish to make it so big that it can't respond properly to the pressure difference (vacuum) signal & make the engine stumble oddly at "tip-in", making it a miserable handful to drive. So, since this method of decision affects the gases flowing in, it only makes sense to apply it to the gases flowing out as well.
Now that I've got that clear, let's go into it a li'l further...
Carbs... since they're typically used in natural-aspiration apps...are flow-rated under 10.5 inches of vacuum-drop. At least most of them are (Don't get me started about Holleys used on the Mopar 440-6pk!). Using this as an initial guideline for which to base research into flow-rating which exhaust-gas handling parts to choose from, we can then slowly go through trial-&-error in learning where's the point where anything larger would be unnecessary & contributing to increasing exhaust noise.
Thankfully, David Vizard (Contributing editor to Popular Hot-Rodding Magazine & writer of several technical automotive performance books) has done all this for us, and findings show that when going with a size of pipe that has a flow-rating of more than 2.2cfm under 10.5in of vacuum drop (Or 10.5in.hg.) there is no (like, as in: About zero!) significant increase in an engine's power output. Hence the term: 2.2cfm@10.5in.hg. This applies to all pipes, resonators & mufflers chosen to used in the given app. As for specific brand or design, that's just a matter of taste & the result desired in terms of exhaust tone.
Use mandrel bends, not cheapo press-machine bends, and good luck!

Well, turbos themselves do act like mufflers... So adding a electric-cutout would be a good way to go when you're ready to race.

this.
when my ecotec swap is finally completed my exhaust setup will be as follows:
pacesetter L61 header
magnaflow highflow cat
18"-22" resonator (cant decide which length really want)
vibrant cat-back
full 2.25" exhaust
ofcourse the resonator will be welded where the cat and vibrant cat-back meet up.

Thanks! This is useful information.

Oh yeah... To get the pulses to think they've reached the end of the system at the end of the header collector & help the rest of the system, built following the guidelines I mentioned, to work properly: Use a catalytic converter with an interior volume equal to that of one cylinder being drawn from by the header. This will isolate the pulses in a effectively make-shift "pressure-wave" chamber that will allow the rest of the exhaust system after it to merely serve duties of handling/reducing noise & carrying the spent gases to the tail (Or somewhere along the side, if you want you system laid-out that way!) of the car. This is another tip from Mr. Vizard.
Go beyond the "bolt-on".
If you check out the Cherry bomb Extreme muffler it offers a single inlet dual outlet when I first installed it I cut the cat out and put in place of them pipe the rest via one outlet, closed the second with a make-shift cap( cut the bottom off a Spray paint can and used a screw type clamp) When I was driving around the streets daily I kept it that way and when I wanted to rip I removed the second cap and doubled the flow!! Also when I did my downpipe the first time I did a manual cut out right from the header with the opening going down, sounds nasty but best flow for maxxing out boost.
