But is it really a 3” exhaust system?

    So after putting this out on other forms of media, I asked about what I found in my new Belangers headers, midpipes, high flow cats system with a full Magnaflow cat back. It’s advertised on multiple sites as a “complete 3” exhaust system that requires no cutting or welding, full bolt on”. Well, I call BS on the 3” part, cause there’s a reducing section right before the mufflers. After looking into this I’ve determined that the reason is because either one of these kits by themselves are meant to be a direct bolt on to our stock exhaust. In order to eliminate the reduction (which is down to an ID of 2.25”) I’ll need to have my welder guy do extra work to make it right. I’ve attached some pics which those of you that have either will (should) recognize. I’m sure that most that have serious mods (unlike myself) have already remedied this themselves but I’m only surprised because, as a vendor selling the combo, they should’ve been noted the restriction or at least modded it to be a true 3”. I’m very disappointed truthfully but I have faith my welder will take care of me.

    Ok rant over, just wanted to make some buzz over this cause I think it’s not right. I can only blame myself for picking the vendor I did. (PS, they list is as a “complete full system”)

    The year is 2020.
    Exhaust systems continue to be a pain in the butt.

    I'm anxious to see what you think about the power differences once your new system is fully installed.

    Me too, but unfortunately I have to do the clutch first which is getting really bad and slipping for the last year and a half since I bought it. I’ve really never known how good it’s been to begin with. So it’ll be a little hard to tell using the ole butt dyno. I do have one 0-60 run in my accelerometer but since it was slipping only achieved 5.6 seconds. And that’s with a 1500 rpm launch and unable to spin the tires. Couldn’t even floor it till it got going without the clutch slipping.
    With all the other restricted piping from the previous owners exhaust mods it should sound a lot better though. I did however seal up the OEM cold air intake route and has a noticeable amount of suction by the grill behind the headlight when blipping it now. The original 15 year old (dry rotted) tires probably won’t help either so I have all 4 new ones ready to be mounted too.

    And I think the accelerometer recorded a HP level at the wheels of 415 if I remember. That should all change once the clutch is good.

    New Clutch
    New Exhaust
    New Tires

    Sounds like a recipe for some fun!

    Soiling of underwear is a real good on road dyno result hahaha
    I love these trucks so many easy hp to gain from simply taking care of those"Mass Production Atrocities" as I call them.
    Reducing the fuel waste is another guise I use here in NZ as the cost is prohibitive
