Dual exhaust

[GrandAmSSE]

I was wondering if anyones kept the original exhaust pipe but used a cut-out or splitter to make a dual exhaust setup?

[Mike94SE]

Not yet.....

It would be hard to get a second pipe over the axle. The one pipe hardly fits.

[Mike94SE]

I think he means after the axle, with the cutout before the muffler.

[GrandAmSSE]

Yep. Think it would work?

[Mike94SE]

maybe. electric?

[GrandAmSSE]

You mean the cut-out? I was thinking a splitter and keep it open full time. Would it help the engine breath any better?

[Mike94SE]

In that case why even have a muffler?

[DontPassTheFence]

you mean a Y-pipe after the axle? with dual mufflers and dual tips like the 92-98 Grand Ams have already?? Also, true duals (2 headers feed 2 cats and 2 intermediate pipes, back to an x-pipe setup and dual mufflers? would be an absolute waste on any engine offered with a grand am. However a Y-Pipe after the axle isnt too hard, and it looks good enough (even though one pipe back to a single inlet and a dual outlet (usually tranversely mounted) would yield dual exhaust tips and it doesnt provide the extra restriction that dual mufflers usually do. (My dual mufflers are both drooping, one more than the other and its terrible)

[Mike94SE]

I dunno because a y pipe (http://store.summitracing.com/default.asp?Ntt=y+pipe&x=0&y=0&searchinresults=false&Ntk=KeywordSearch&DDS=1&N=115&target=egnsearch.asp) and a cutout (http://store.summitracing.com/default.asp?Ntt=cutout&x=0&y=0&searchinresults=false&Ntk=KeywordSearch&DDS=1&N=115&target=egnsearch.asp)
are different things

You'd be better going with a dual outlet muffler, like a Flowmaster 80 have it installed before the spare wheel thing and have two pipes w/ tips coming back.

[Mike94SE]

I may have a dual setup; but I'm gonna use an actual cutout and some piping to the other side.... I gotta see. Or maybe a Y pipe and use a TB. I dunno

(Yes it is a waste N/A... I will NOT be N/A....)

check this out, you can keep your stock exhaust and still reap all of the benifits of strait headers: http://www.pfyc.com/store/merchant.mv?Screen=PROD&Store_Code=PFYC&Product_Code=GN5002&Product_Count=2&Category_Code=GAEXH

hmm, that's interesting. Kinda cool, you can have the backpressure of stock exhaust for take off then open up for higher speeds. Hmm, now I kinda want one :)

[Mike94SE]

Man just get a manual one, a 45* pipe so it faces straight to the back, and weld a TB with the idler screw removed. Cable actuated; much less.

Much cheaper than $150 for that

That thing gave me an idea that will save me some hassle. I use a CAI during the summer but convert it to a WAI during the winter primarily because I don't want water getting into my engine. I could just hook that right up to the throttle body and have one part going to the cai filter and the other with a filter inside the engine bay. What? Deep puddles? *click* I love it.... I also found one for way cheaper: http://store.summitracing.com/default.asp?Ntt=cutout&x=0&y=0&searchinresults=false&Ntk=KeywordSearch&DDS=1&N=115&target=egnsearch.asp

Go look at a GT exhaust...

???????????????????????

WTF?

How does this relate to dual exhaust?

It doesn't, I was just saying I got an idea for another use for that thing....

Someone told me I'd have to put that splitter after the cat which would make it "pointless" according to him, is that true or is he just saying that because it would make it legal?

I'm not sure I get what you're saying, what is the TB gonna do?

[Mike94SE]

With a lever inside the car (and the idler screw removed), it's a cheapo manual cutout

I see, you want it so you can run onthe stock exhaust or on an open design (even though with the cut-out the exhaust is still HIGLY restricted by the exhaust manifold, downpipe, and cat (or header/cat/interemediate piping with a n/a application)

Either way Id say it looks like a waste for all that $$. I could see the need for this while running a turbo setup, but then again my friend runs a SAAB turbo on his ecotec cavy, and he fully used the stock exhaust piping (but got rid of the resonator, got a high flow cat, and took off the muffler) and he runs low 13s easily with that car set to only 7-9 PSI (intercooled of course)

The thing isnt loud at all, and it flows more than well enough for the turbos capacity (13PSI is max IIRC)

[GrandAmSSE]

I got to get my turbo put in.
