true duals or straight pipe? firstly hello to you all, my names kyle i live in the uk, ive been lurking around this forum for a while now and decided to join......
my car is a 04 ls1 vauxhall monaro (pontiac gto or holden monaro) 330hp cv8 model.
the car has a true dual exhaust as standard with h pipes.
i removed the mufflers and now the car sounds like a tractor on idle but awsome on song.
im thinking of going single, with a y-pipe and a 3inch pipe all the way to a sports backbox.
the question is due true duals offer a power gain?
and how does a single pipe sound?
hope somebody can help me.......
cheers kyle

hey there k15! i have a 04 gto with the exact same settup you mentioned. i had it custom built for a custom sound. we took a 3" stainless steel pipe and made a y 4' from the headers, then we y'ed it into a single 31/2" pipe that runs over to the left exit. we took a dynomax muffler they are the only ones to make a full 31/2" inside diameter muffler. the sound is awesome. i have had more people walk out side and tell me my car sounds like no one elses. it will also be able to flow enough exhaust gasses to support over 1000 hp. when my son gets home i will have him make a video of the exhaust. if you will go to ableraceing.com you can see my exhaust as they were building it. all i can say is do it! you will not be unhappy. and you also get absolutely no drone when the windows are up. roll them down and crap it is loud. best exhaust i have ever had built. when you go to able's site, ask andrea to explain how and what he did. they are very good people... kerry!!!

thanks for all the replys guys.........as i said earlier would the x pipe get rid of the tractor like idle? im wanting more of a deep[ burble.
my duals can only go into one box, due to the fuel tank being over one side of the back axel as you can see in the pic.

I have had a ton of different exhausts on my car. My favorite by far is the Corsa Touring. It comes with an oval tip that fills the bumper hole nicely. With your gas tank in the correct location (instead of trunk like us) you are limited to that driver exit. I have had magnaflow, Borla, SLP, Corsa, and Custom exhaust. The Corsa Touring would be the way to go. Now if you were going to go to a side exit then that would be a different story all together. Get your rear bumper filled and have your side skirts altered. That would be a sweet setup but would cost a good bit.
Good luck in your choice.
Also look for the 06 black tail lights, it will really set your IBM off

, ive considered side exits but i think would just be epic lol, i want to keep my eardrums......il have a look at the touring but it seems an expensive option with the dollar/pound atm, plus theres shipping to deal with!!
its a real shame theres not much of a v8 scene in the uk, parts are so expensive, not to mention fuel.....
but they are a few of us who keep it going, also trying to figure out a custom true dual for my mates 99 camaro z28, but thats a different story!!
once again cheers guys

I wouldn't recommend joining the exhaust at any point if you want a nice deep sound. Joining the exhaust will help with scavenging but if your blown it will not matter.
I had Corsa Sport on my 05 GTO but like the C5 Z06 titanium with no cross over better.
Anyone do true duals with Z06 titanium mufflers? I have a procharged CTS-V and put them on and really like them. Here is a video from an autocross and a mock up picture as I attached them right behind the cats.

You may have gotten your exhaust already but incase you haven't this is what I have. And I think it looks the best for the 04's. My exhaust is the spintech catback with x-pipe.

still havent got it! how have you got a backbox on the other side? i cant due to my fuel tank being there, i think in america your tank is located behind the axel for safety reasons?

You are right, the 04 Vauxhalls had the fuel tank on the right side. Yes the US GTO's have the fuel tank right behind the rear seats. I can post some pictures from underneath and you can see what it looks like under there.
