Custom SS Dual Exhaust on Alpha Installed Today - Page 2

Was hoping to see the configuration underneath or is it just chopped in after the cats?

The old system was cut off at the mid-cabin resonator and the new muffler was installed in it’s place. The dual tailpipes exit the muffler side by side, then split and exit at the locations you see in the pictures. I forgot to take my camera when I had the system installed and when I took the pictures the weather was miserable, the temperature was 17 degrees and I was not about to lay on the ground to try and take some photos of the underside. But, as soon as we have a nice day I will indeed get some pictures of the dirty side of the truck for all to see.

Here's a photo of the underside of my truck showing the new custom SS exhaust system and how it exits the rear of the truck.

What has that got to do with anything? I got shot twice in Vietnam and sometimes have a little difficulty walking. That has nothing to do with the type of vehicle I choose to drive.

Exactly!!!! what does that have to do with anything????? and why would it!!!!!

ok...now post the SOUND clip ;)

I don't have any idea how to post a sound clip.

Same to you kc4ww and thank you, you too Alpha if I never said anything before:
 

alphadogg,
Didn't mean any disrespect by my comment.
If you took it that way, my apology!
My hat's off to you for your service to our country!
I served on a tin can that was stationed off the coast
of Viet Nam for a short while.

Very Nice clean setup, I don't think any aftermarket companies could do better.

Thank you gentlemen and thank you to all our veterans on this forum and our service men & women presently serving in our armed forces. When they come home from the sandbox they'll need all the support they can get.
 
Now back on subject. The trouble with the aftermarket exhaust systems that I've seen that are soon to be available is that are the same as the OEM systems except with a performance muffler and dual tailpipes. The muffler is still in the same place as it is now with too many 90 degree bends and the tailpipes just come off the end of it. Just too many restrictions!  

I found a place to do mine...should be on next week, I'll post up after its done :)


Thanks for the motivation alphadogg :)

You are very welcome. I just love helping people spend their money!

You could always go my route for a fast, cheap temp fix
 

 
I plan on cutting the main resinator off that is under the middle of the truck and replacing with a magnaflow or 40 series Flowmaster. I think that should probably be pretty close.

You mean you can just cut out all the stock crap behind the cat and throw a performance muffler in the system and away you go? Why did I spend all this money on a Magnaflow system? I thought everything had to be balanced and properly "tuned" to make it function properly with the newer more sophisticated engines...I like the old fashioned way..Let us know how it performs! And how loud it is...

hey alphadogg, what did they do after the front cats where the stock pipes flattened out?? Do 2.5in pipes fit past the driveshaft?

They don't do anything special when stick those systems on your truck. I'm going to put their muffler under the belly where the resinator is anyway. I just took a short cut and cut rear can off. Saved a couple hundred bucks. It will sound better once I put a deeper toned muffler on it. Keep in mind, it is an I5. It's only going to get so deep.
 

Sorry, forgot to mention about the performance that you asked about. I can't actually tell you that it's from the muffler being gone or it it's a combo of that and the new AirDoc intake but it does have alot less restriction on take off. Don't have any actual "numbers" to post. But I can tell you from driving that I definetly FEEL a difference. I did something similar to this on my old Dodge Ram and never had a problem with it. If you need more confirmation HUNNER, JEEPEATERH3 have also done this same mod and as far as I know, no problems!

They cut the pipe off just behind the y-pipe after the mid-frame on the truck and welded the new muffler there and then custom bent both tailpipes to run parallel to each other before splitting where they exit out the back.
 
I wish I would have remembered to take my camera when they did the installation so I could have had some photos to post.
 
I can feel the difference in power and I think a high-flow air intake will definitely help (air in-air out) when one becomes available. Plus I ordered the PMC upgrade which should be coming sometime this week so that should really give me some extra gitty-up. BTW, the sound is outstanding! I get a lot of looks now when I drive by where before I wouldn't!

Alpha, how much different of a sound is it compared to mine right now? Just curious as I'm trying to decide on the right muffler.

I had a choice of 3 levels of sound. 1st was quiet, 2nd was med. loud & 3rd was loud! I choose the 2nd because it was a nice deep mellow sound but had a nice rumble to it when I gave it the gas.
 
Your truck sounds louder and a bit harsher, just like it needs a muffler. It does not have that deep mellow sound and I think dual tailpipes compliment each other.

ahhhhh, I thought you said they removed the 2nd set of inline cats way up front. If anyone hasn't seen what GM did to pass around the driveshaft is missing out on some comedy.

So your system has a muffler where the stock res was and builds the duels from there. Cool.

Nope, my muffler shop would not remove any of the cats nor would I want them to. I think that's when you get into trouble is when you start removing the emissions stuff! There must be a reason they put 4 cats on the H3 and the computer would probably throw a code if you removed two of them.
 
I’m due for a oil change soon so when I get it done I’ll be sure to get some pictures while they have the truck on the lift.

I get what you are saying Alpha and as I said I do plan on putting a Magna/Flowmaster on it in place of the main resinator. But, while I was driving home from work I was thinking about this thread (yes, I know it's sad that I think about this place while I'm out driving ), and it was silly for me to ask you to compare mine to yours. You have an Alpha!! OPPS!
