Dual Exhaust Ideas?- Pics - The 1947 - Present Chevrolet & GMC Truck Message Board Network

k5hart · 06-11-2004, 01:09 AM

Hello everyone,

I know this is a subject that comes up from time to time, but I am going to start it again. Lets see some pics of your dual exhaust routing. I am hopefully going to do my exhaust on the blazer soon and want some ideas. I am thinking of running the exhaust off the sides behind the rear tires. Would like to have it as tucked up as much as possible. Need some ideas.

Thanks, Jason

I run 2.5" Corvette ram horns connected to 2.5" aluminized exhaust tubing.
Dual Dynomax Super-Turbo mufflers.The exhaust exits behind each rear wheel.
Oh ya,I also run an "H" pipe just behind the transfer-case.
Here are some pic's.

The muffler

the Corvette ram-horn

cross section of the tubing

the "H" pipe

looking towards the rear

how they exit

The whole system has a low,deep tone to it but really screams when you get on it

ttt..........

2low72 · 06-11-2004, 11:23 AM

Here's my setup

k5hart · 06-11-2004, 06:35 PM

Any one have any more pics of this system. This is kind of what I had in mind. Where are the bends made at the back to angle the pipe down?

Thanks.

My exhaust isn't even that far back....the front of my mufflers are right behind where the carrier bearing mounts to the xmember.

I have never had anything said to me besides when I got pulled over in the middle of winter during a snowstorm and the lady cop asked me if i had catalytic converter's on it still...... I told her the truck didn't come with them. She then proceded to write up a nice big ticket for me for being a smart ass.....

Mine has been like that (but with glasspacks) for at least 20 years....

2low72 · 06-11-2004, 07:45 PM

It should be it's the 3rd truck i've had this set-up on

Time Travel · 06-11-2004, 07:58 PM

I'm currently running mine out the side in front of the tires. IMO with a stepside it flows better. No pun intended.

Goffer · 06-11-2004, 09:53 PM

time travel, you have any pics? thinking about something along those lines.

LUV2XCLR8 · 06-11-2004, 10:15 PM

I'm Doing Mine Like Time Travel, And For Tips I'm Using Aftermarket
Chrome (or Stainless) Camaro Replacement Tips, They Are Flat And
Rectangular So They Will Tuck Up To The Body Like Nascar Exhaust.
(About 1-1/2 inches high ( maybe 2 ) and about 5 or 6 inches wide )
Now that I think about it, they are 2 x 6 because that translates 3"
round if you were using the standard type of exhaust tips most use.

greasemonkey · 06-12-2004, 11:37 AM

Here's how mine runs...

Actually... 2x6 = 12 sq. in. 3" diameter = 7.07 sq. in. However, that will work just fine.

2low72 · 06-12-2004, 09:51 PM

kinda like this Stocker, this is what I replaced with the flows

chevjayfsd · 06-13-2004, 12:47 AM

Mine

LUV2XCLR8 · 06-13-2004, 07:04 AM

Uhh, Ok Xxl, I'm Not The Technical Type, The Exhaust Shop Near Me
Says The Tips Flow About Like A 3" Round Since They Are Not Round.

k5hart · 06-13-2004, 11:54 AM

Thanks for all info everyone. Some good ideas. Keep them coming!

fast71 · 06-13-2004, 12:14 PM

hey thats my truck !!!!!! do you want more pics?

boraxman · 06-13-2004, 12:38 PM

Mines done similar to Geasemonkey's except they go in instead of along the frame. They also have a H-pipe up front. Nice setup.

fast71 · 06-13-2004, 12:40 PM

here is a few pics

dinnut · 06-13-2004, 02:02 PM

wes, those x-pipes actually connect and there is an opening between the two pipes right? what is the advantage over an h-pipe or is it just about the same?

**Classic Heartbeat** · 06-13-2004, 02:14 PM

Yes they do connect and yes there is an opening between them. The advantage of the "X" pipe over the "H" pipe it's the ability to scavenge is better. The "H" pipe tends to creat turbulance at higher RPM due to the fact it causes the gasses between the two sides to flow perpendicular to the natural flow of the exhaust. The "X" pipe however keeps everything flowing in the same direction, increasing it's abillity to scavenge. Especially at higher RPMs. WES

k5hart · 06-13-2004, 07:42 PM

Fast71 - Thanks a lot for the pics, I was really hoping some would pop up. I was considering your set up, but wondering if you could see the pipes through the wheelwells when looking at the side of the truck. I like the short turn down out the side. Its clean looking.

Racedvl - You got me thinking too I really like your set up also. I am going to have to take a look at the truck and see if I could do that without my gas tank and hidden hitch getting in the way. Again, I like turn down look.

Jason

fast71 · 06-13-2004, 09:19 PM

Jason ,I will look tomorrow and see . Thanks Brian
