Enough Power to Warrant True Duals I have a corsa exhaust that I like and I was going to get pacesetter headers and a tsp Y. I really am thinking of true duals though as I live close to the legendary Lane's Duals Shop in Dallas.
My question is:
I will never produce more than 350 RWHP -will I see any signifcant increase in power with headers and true duals over headers and Y with my relatively low RWHP?
I am thinking that the headers and Y pipe will give me more than enough flow for my RWHP and that the true duals will just be unnecessary excess.
Im thinking the true duals are kinda like getting 2 gauge wire for your speakers when you're only flowing 15 watts, when 16 guage would have been plenty.
Thanks,
Lane

Lt's and TD would be worth it to me just for the sound. I am in a similar situation right now. I think it would be better to get the TD now the regret it later. As for power TD will make more hp than a y set-up. As far as how much more that is a hole new topic.
look at it this way. A mustang GT with a 4.6L has only 230hp at best and will use a dual 2.5'' with Ypipe. Now do you think your 350 will be putting out more exhaust than a 230hp 4.6? I say go for it. Ive heard of f-bodies being able to fit a 2.5'' true dual setup that actually will fit over the axel so you can get some nice corsa tips on it. Theres actually a SOM z28 down the road from me with a dual setup going over the axel. good luck.

Does no one read the STICKYS???
A 3" Y setup will easily flow enough for around 500bhp.
What will restict you is CAT and MUFFLER flow rate.
Use 2.2cfm for every 1hp as a guide.
If you go to big it may hurt the low end a little.
Headers should make a big difference, especially at higher rpms.
But 350rwhp is pretty strong for a bolt on car. Let's be optomistic and say with all mods you car will be producing ~400bhp at the engine
400 x 2.2 = 880cfm flow rate. This is your flow rate of all 8 cylinders.
You only have 1 CAT per bank so they only need half the flow rate. If you go duals then each muffler also only has to handle half the flow rate.
With a Y the muffler(s) need to flow at least 880cfm to NOT affect backpressure and reduce BHP. There are lots of mufflers that exceed this level, but many that don't. So check before you buy. If you design it right then cut outs will offer NO or at least very little gain.
Duals do sound good though.
Here's an idea of components:
Pacesetter headers/Hooker more expensive/Kooks or QTP probably better but not by much and cost more.
Random Technolgy CATS, 9000 series is fine and will flow well enough. Or maybe 8100 bullit series as they are smaller. If you think more power is on the horizon go for their Metal Matrix 7000 series units, they flow 550+cfm which is good enough for more than 500bhp.
Mufflers, lots to choose, Borla and Dynomax both make good enough units. Powerstick are my choice though as they are a classic chambered muffler and flow well enough for over 800bhp. Stainless Works offer something similar but in stainless, although I believe a slightly different design.
H pipe, get the shop to fab it up, or there are some out there.
X pipe, I quite like the Magnaflow design, as it's fairly compact and has a good reputation, but there are lots out there.

The answer is no, once a thread turns yellowish, its an automatic "don't read me" sign.
And, btw, Lane's shut down his shop about a month ago. He's only fabbing up duals out of his garage now, so you can get a setup made off a jig, but no more setups made on your car afaik. At least thats how it was last time I talked to him.

Do the duals. You'll love the sound, and every other car will sound neutered compared to yours.
Plus, if you want to go bigger on power down the road, you can without worrying about replacing the exhaust again.

ALright. Cool thanks for the all the info! For the record I did look at the exhuast stickys but must have overlooked that info or not found it specfic enough.
Thanks again for all the help!
