After a long time of the original picture collection being down I've finally put it up again. I'll be adding more pictures and redoing it all pretty soon ...I'm kinda lazy though.

Glad someone did this...

A picture is worth a thousand words, and both those sites have alot of pictures

Willy, how much did it cost to get that system done? Do you think it was worth it for the performance and sound?

Thanks for the info guys

Matt,

Before I had my exhaust done, no one I knew of had accomplished a true dual setup using the stock routing. Also, no one I knew of used a pair of chambered mufflers. All the pics of other systems I saw were crude, at best -- most had so little ground clearance that I would not be able to drive into my driveway. Most had mufflers hanging so low they were tacky looking. I like doing things slightly differently and decided that I was going to make it happen. I like to think I accomplished this. Because mine uses stock routing, ground clearance is not an issue and all the pipes look like they belong where they are.

The sound is awesome. Here's a sound clip:

It turns heads wherever I go. As for performance, I do not have before and after runs with only the exhaust being the difference. Therefore, I cannot quantify the improvement, if any.

The complete system was not cheap, but I did NOT cut any corners. I used very expensive mufflers and bought six 180 degree mandrel bends (to be cut to desired length by the installer). I also used a pair of Flowmaster "Ys" to act as an "X" pipe. The shop I had the work done charged $60 per hour, which included the straight sections of pipe. It took them five hours.

To minimize the cost, have the shop supply and bend all the pipe and do not use an "X" pipe. Also, use a much cheaper pair of mufflers and the cost would probably be half of what my total was.

Willy, your sound clip just brought a huge smile to my face. At least I found my springtime project now

Thanks man

We should make this a sticky. 88IROC350TPI, that is an excellent site with all the pics of dual exhaust from TGO, very nice, it's going in my bookmarks...

camaro of solar · 10-10-2003, 09:07 PM

question...how much would a set up similar o this run?

IROCNParts · 10-11-2003, 11:48 AM

mine is the second one on the first page

you forgot to say its true dual 3"

Cuno · 10-12-2003, 03:12 PM

sweet! I was just trying to decide on a way to run a true dual exhaust and I wanted to do it along the stock exhaust location...what I was wanting to do is already pictured so it will make it that much easier to do! Thanks for those great pics!

1989RS · 10-13-2003, 03:42 PM

great site, i think it would answer at least a third of the questions in this forum, lol

KagA152 · 10-13-2003, 10:36 PM

does a member on the board have the first car the 92 z with x pipe and bullet, i wanna hear it!

91z383stroker · 10-26-2003, 09:11 PM

Hey man whats up i was just wondering, do you have any more information on the red camaro that is first shown on that exuast page of yours that has dual 3" into X-pipe and out to 3.5" dynomax bullets. Is he a body or have a web page that has info on that car. I was just wondering bc i want to find out what size of rims and tires he has out in the rear. and just want some more pictures of his car, bc it looks good. I have a red z28 91 and it looks just like it minus the rims and hood. hope u can help, cya

88IROC350TPI · 10-26-2003, 10:04 PM

The guys name on here is "The Man" heres his post where I got the pics from: http://www.thirdgen.org/techbb2/show...hreadid=182537 (Just got trur duals installed with hooker longtubes)

joshwilson3 · 10-26-2003, 11:14 PM

I have a question that may sound redundant, but I'm gonna ask it anyway cause I have limited experience and I am not a third gen specialist.

I am looking at going true dual exhaust. I have a 1989 Firebird LO3 305 V8 Automatic that is in stock condition. I am wanting to do a whole new exhaust system to help my engine breath easier. Now, keep in mind, this is just a little 305, so I am not planning on going too crazy on spending. I figured that I would go either hooker or hedman headers. I will probably go with hedman because of the price.

From my repetitive searches I have found the following to be the best for my application. And I live in Tennessee with no emissions.

For my 305 I would need, 1 5/8 inch primary long tube headers, 2.5 inch pipes, and X pipe. As I said before I will probably be going with Hedman long tube headers. From there, I believe I read that I need to use their X-tensions. I would like to run the pipes down the center of the car and dump like either in the middle or out in front of the rear tires like a side exit.

My question is this:

It looks as if there is room to run two pipes along the middle of the car, you would need them to go around the transmission pan. This is where the problem is, there is metal braces or something around part of the Trans pan preventing me from having one of the pipes following in the groove. Can I remove some of this metal bracing? Can I relocate to a different side or something? I am not sure what that stuff is for, but I believe if that stuff if gone, that I will be able to have two pipes leave the headers and stay in the groove and go around the Trans pan and on down the car. This seems like the worst problem for the piping. I haven't done anything yet. I am in the developing stages of figuring out what I am going to do. I want true dual. I will probably use some loudmouth style mufflers. Can anyone point me in the right direction?

I will probably jet coated hedman headers, any suggestion as to what type of hedman? They have street, step, Extreme duty, and race headers. I don't know which one to pick.

Here are some pics of some other Hedman exhaust stuff that I need your opinion on if you think I would need this or if it would help my project.

88IROC350TPI · 10-26-2003, 11:48 PM

You'd be so much better off with just a single 3" system. TRUST ME

joshwilson3 · 10-27-2003, 01:18 AM

Maybe, but I want true dual. I want to get as much power out of my little 305 without compromise. Also, I like the idea of side exits or something like that.

88IROC350TPI · 10-27-2003, 03:28 PM

heh ...well, looks like the site might be goin down soon unless, of course, someone wants to host it on a real server

heddman longtubes, xtensions, moroso spiral muffs, turndowns. going to get an h-pipe soon though.

ChrisFormula355 · 11-04-2003, 02:27 AM

I'll post pics of mine tommorow. I had a custom mandrel bent 3inch X pipe system with the traditional muscle car routing, and they had to install the mufflers in the rear location where the factory crossflow was installed. With hooker long tube headers, 3inch piping, x pipe and 3inch stainless magnaflows, it sounds badass. My car is lowered too, and it doesn't have any clearance issues except over steep dips or big speed bumps, which I can manuever over. I was really amazed at how the shop (eastside performance exhaust) tucked up the dual 3inch pipes so well on a thirdgen of all cars.

iroczrockz · 11-04-2003, 04:15 PM

Hey you guys what kind of muffler is that, that is used on either side of the gas tank? Looks small and discreet. That isn't made by Borla is it?

iroczrockz · 11-04-2003, 04:17 PM

Sorry, guess I should of put in a pic.

kfoley · 11-04-2003, 10:23 PM

Hey mw66nova, how loud are those moroso spirals? I'm thinking of using them when I get the new motor.

mw66nova · 11-05-2003, 09:33 AM

you know, i thought that they would be louder than they are. inside i can still have a conversation with someone, they are really mellow for being a race muffler. i am not saying they are not quite by any means, but they are not obnoxiously loud. and they have a really cool bark when you step on it. i wish i knew how to post videos.

iroczrockz · 11-08-2003, 07:32 PM

Are they going to be too loud for a street car?

kfoley · 11-09-2003, 12:14 AM

I have duals with 3" center in/out aerochambers and it's kind of loud. You can see right through the mufflers... Got a pic of it around here, I'll try and scan it in sometime. Anyways, I've been thinking hedman longtubes and the morosos. From everything I've heard they're more bassy than actually loud (unlike the bullets which barely muffle). I honestly don't think they're louder (or not by much) than my hookers. To have a converstaion in my car you have to raise your voice quite a bit. My dad doesn't even like riding in my car cause he says it's too loud, lol and he's a car guy! So what's your opinion 66nova? Oh, sound clips would be cool too...

honestly, depends on two things...
A. what you think is loud
B. what your cops in your area think is loud...

probably too loud for most peoples street cars, but i will drive mine everyday anyways...
