Exhaust Leak...EDIT:Rethinking the whole idea...

Duals you can buy a dual kit that will bolt right on and baring hanger issues will be DIY in your garage.

Singles are more complex. You can piece it all together using a Walker Y pipe, getting a cat, and then a Flowmaster single exhaust setup from the cat back. Won't be as trick as a custom single setup but will be a single 3" setup. Will have the Y going under the trans as the factory setup did.

I was ready to go single with mine but unless the guy throws me a cheap price on it then I'll probably just go duals for simplicity.





However the most genius thing you've said was to pick up another vehicle. DO IT!

Get that truck out of the winter crap or it's all for naught anyway.

This looks decent, 2 1/4" duals, application specific to a Blazer, and you could install it with hand tools.

Made for header back.

Will 2-1/4" work with a 3" collector diameter though? as found on the hedman elites

Thermal coated with the 3/8 flange and you can't go wrong. Been running mine for 3 years and they still look great, no rust. The 3/8 flange stays nice and tight, no leaks. I bought the offset extensions which connect to the ball flange and went up and over the cross member with them. Thus i'm running true duals.

Where did you get yours from? What is this offset extension you speak of? is that how you go from 3" to 2 1/4?
 
Got mine from Summit they are called Hedman extensions. The are made for various size pipe. Tried to post up a linky for ya, but no worky. Just go to the Summit web site and search for Hedman extensions:waytogo:

Lol. I think I've heard someone say that somewhere on here before.. :doah::haha:

I'm not sure that the walker Y pipe would work with the long tube headers.. :thinking: some modification would be required. Unless I go with the shorty headers.

Oooooh, yeah, the Walker Y pipe is meant for stock manifolds. So only shorty headers with stock dimensions would work for it.
 
Yea I think I'm going to have to stick with duals if I want simplicity with long tube headers.

So, this is what I'm leaning towards:

Hedman Elite's $325.95 USD

Dynomax Header-Back Dual exhaust kit: $149.99 USD

and a couple of these Dynomax Ultraflo mufflers: $77.95 ea

Brings the total to $631.84 :woot: plus shipping to Canuckistan :doah:and taxes, duty, fees, etc. :doah: :doah:

I may add some things like perhaps an H pipe crossover kit and who knows what other odds and ends the kit will be missing.




Please tell me if I'm missing something or I'm on the wrong track. I really appreciate everything you guys have shared :bow: Thanks for helping out a nOOb.

I think I'm going to tackle this one myself.

Yeah that should work. I see the pipes already have the offset in them so that's good. Now to keep it simple, you need to know what the ID dimension is on the header end of pipe. Then you can get the proper extension OD dimension (straight not offset) that connects to the ball flange (you will have the offset in your pipe already). I hope this makes sense, and it should work. As far as true duals, I wanted to keep it simple with mine to remove drivetrain and related parts so no x-over for me.
 
One more comparison thought. If I went with single exit 3"....

(Thinking about this again in case of potential 6.2 diesel conversion in the future, manifolds would line up with the walker Y-pipe)

I would go with shorty headers instead of long tubes, so I could put the Walker Y pipe.

Question: How much work to make '88-'98 Chev body style headers fit on '73-'91 style truck? I think I remember reading about clearance issues, although fixable. Not sure about the edelbrock ones though. :dunno:

Reason I ask is Edelbrock has discontinued a bunch of parts. I can get my hands on a set of these though \/ \/ for ~$500.00 CAD

OR

Gibson Ceramic coated $581.25

Doug's ceramic coated: $698.95

Flowtech 31504: ceramic coated 5/16" flange $265.95
big-31504flt_w.jpg

http://www.summitracing.com/parts/BIG-31504FLT/?rtype=10
 
So my total for the 3" single would be around $974.31 plus shipping, duty, taxes, etc.

Breakdown:

Shorty headers: ~$500.00
Walker Y Pipe (landed here): $264.36
3" exhaust extension in place of catalytic convertor: ?? $
Flowmaster Cat-back exhaust kit $209.95

Interesting. Never would have thought it would have been less expensive for duals and headers.. :thinking:
 
couple things,

those headman's with the coating are awesome. i have installed alot of them and had a set on my 400m. verry nice. thick and no leaking

you could install new stock manifolds very easily by yourself. just get all new hardware before you start

dont look at flowtech. absolute junk

make sure if you buy tubing that its aluminized

i would splurge for stainless mufflers. they will last alot longer. water always sits in the bottom of the mufflers and they will rust from the inside out.

You don't pay 'duty' on US made automotive parts. You will pay any applicable PST/GST (whatever taxes your province charges on stuff), UPS will ding you for brokerage fees, and of course there will be shipping charges. You're still gonna come out way ahead IMO, and you can literally do it all yourself in the driveway or garage.

Shorty headers are an expensive compromise, usually more spendy for less performance. You will like the Hedman Elite's...literally every review I've read here gave them a big thumbs up.

i find driving habits dictate muffler life. Make lots of short trips and it'll rot out in a few short years. Make longer trips, ensuring the mufflers get hot and they last a lot longer.
 
My only question is if that exhaust kit is meant to run with the long tubes?

Aside from that, sounds like a plan. Interested to hear how it sounds. I'm slowly pondering muffler choices for mine.
 
For sure that system is for long tube headers, it's the more common header...so if it was meant for shorties it would specify for shorty headers. Also, neither pipe curves up going by the pictures.
 
Derp...yeah...very good points.

It's late...I'm blaming it on that.

I'm just wondering if this dynomax kit will bolt onto the 3" outlet of the headers. I might try calling Summit to find out.


Well I'm thinking its going to be the hedman elites and dynomax duals. I hope I can tackle this on my own. Never done headers before, thats my only concern. As soon as I find out that I'll have a garage space to work in, I'll order the parts up I reckon. :thumb:

Yes and no. It will not bolt directly to the header. You will need the coupler/extension that has the proper flared end on it to connect to ball socket. Your headers will come with that, and from there what ever it takes to tie into your new exhaust. That is why i suggested for you to find the ID diameter of exhaust pipe. I think the ones that come with the headers are 2 1/2 OD. Although Hedman has other sizes to make the proper fit.
