ECLB exhaust catback fitment

[PinkFloydChevy]

This is my first post on this site. My question is: will a catback designed for an ECSB truck fit my ECLB truck if I added some length to the intermediate pipe? My truck is a 1995 ECLB C1500 with the 350 and i'm planning on replacing the current garbage set up with a Dynomax super turbo catback and splicing in a Spintech 6000, 3'' in and out. I just need to know if the hangers would still line up and any other advice from people with experiance doing this. Or if anyone could suggest a specific catback system that is not outrageously expensive that is made for an ECLB... Thanks.

Why not bring the muffler to a good shop and have them weld it all up nicely for you? Much cheaper and you can have them do whatever your heart desires

In short, i'm more of a diy person (i'm 16 and trying to learn all I can) and my truck doesn't have a cat so I doubt any muffler shop in the area will touch it. Dynomax has the $75 rebate going on so I thought I should take advantage of it but they don't make a system for an ECLB, right now i'm looking at the model 17380 which is a good price even before the rebate. Thanks for the reply.

Welcome to the site, well you could get just a pipe kit from jegs or summit, has the intermediate pipe, over the axle, and 90's and bends then get the muffler of your choice, then you can build it however you want.

[PinkFloydChevy]

Would there be any welding required for the hangers with a pipe kit? Oh, and I should probably mention that my current mods to the exhaust are Flowtech shorty headers (which were a big pain) and a Flowtech ypipe.

[1988 GMC 355]

Well you will probably have to weld hangers to the pipe so you can still use your stock hanger locations, if you are good enough to weld up the pipe yourself then you can do the hangers, and well then you can just build right off the y pipe

[PinkFloydChevy]

Unfortunatly I don't know how to weld, but I could always get some help so thank you for the suggestions. If I were to take off my existing system and bring it to a shop, could they duplicate it with 3" pipe and the Spintech mufler? As long as they don't see a truck without a cat they would probably do it, right?

[1988 GMC 355]

They could build that no issue, now I do not know the laws in your state or what your local shops do, you have to call and ask.

[PinkFloydChevy]

Ok. I don't think emissions laws will get in the way too much in Indiana, I know we don't emissions testing at least... I'm going to sit on it for awhile because I don't get my license till May anyway (Indiana driving laws are terrible) and that's when I plan on putting the louder exhaust on. Thank you for your help!

[1988 GMC 355]

Well whether you need emissions or not is not the issue, it's whether they will perform the work when the truck does not have a cat, my local shop will not as it is a huge fine for them, so I got a $35 high flow cat to put on my truck.
Hope that helps!

[PinkFloydChevy]

Yes, thanks for all your help. I'm trying to figure out the cheapest way to get this job done so the more ideas I have to work with the better.

The Spintech muffler is on the way and I have one more question. I'm going to end up keeping my intermediate pipe but the taipipe will have to go and I want to know if the tailpipe size is different with different cab/bed sizes. I'm looking at a Walker direct fit tailpipe that says it is for RCLB and I don't know if the hangers will be in the same place on a ECLB tailpipe.

[1988 GMC 355]

Hmmm best thing to do would be to call them and see what they say, with that specific of a question, they could answer it best.

[PinkFloydChevy]

I ordered hopefully what is the correct tailpipe from Rockauto so even if it is wrong they will be good about it. I've got High Hopes for this Spintech muffler but i've never heard one in person, how is it on volume, or is there any other muffler that you could compare it to volume wise? I've seen enough videos and read enough on them that I'm almost sure that they will be more than perfect but I need to make sure that my parents won't make me toss it because they're not fans of LOUD. I like the deep sound of a Chevy V8 and that's one reason why I have to have full 3in tubing, it's also why I drilled holes in my current muffler ( I know, I know, redneck) but it worked. From what I understand this Spintech should give a very deep, rumbly tone to it while not drowning out the 70's rock in the cab. Am I right? Thoughts?

if u wanna be able to bring ur truck to a shop to do the work, just buy a fake cat, dont remember the website that sells them, but its a 3" pipe, with a cat looking case welded onto it, looks just like a real cat, but inside its just a piece of pipe....then u could take it to a shop, and considering the fake cat is like less than $50, ur still saving money

[PinkFloydChevy]

I actually thought about the fake cat but decided against it. The tailpipe just got here (shipping was very fast) and it looks to be the right length so when the time rolls around i'll cut the old muffler and tailpipe out and put in the new stuff. Thanks for all your help.

The exhaust on a ECLB is so far back you wont hear any more sound unless you dump it under the cab or hang your head out the window. They are like misfits. I have checked with all good brands and there are no full bolt ons. Try to get those parts welded or all those clamps will piss you off.

[PinkFloydChevy]

I agree with what you're saying completely. But I love my ECLB so I'm just going to make do. I won't mind having my split rear window open if I get to hear the sound of a Spintech 6000!

[PinkFloydChevy]

Thought I'd finish the thread off: the tailpipe fit perfectly and the exhaust is now complete. I could not be happier with the Spintech muffler, it's perfect!

[Quyonmob]

Attaboy. :cheer:

DIY exhaust at 16 with keen attitude to learn, you'll fit in great around here!

[PinkFloydChevy]

Thanks. I love Chevy trucks and I plan on spending more and more time with my truck especially as I get money from a summer job and now that school is over. :bowtie:
