  • 304 SS exhaust system

    It's been a few years since I've posted on here, but I've been building a ton of stuff and now have a CNC plasma table to boot.

    Here's something I'm working on right now.

    Removed the front pipe and mid pipe, beginning the 3" front pipe section...


    Coping with the plasma cutter and a template. I find running low amperage with a 45A nozzle yields less cleanup on the inside of the tube. I'm sure it'd be even easier if I had some anti-spatter spray as well.


    It's tight.

    I used to have a tough time with SS, but now I just love it, I know I can always improve though.



    Rough mock up. There will be a v-band in the long straight section to break up the front pipe from the mid pipe.



    Should be putting down 550awhp when the owner is done with it, it's an R32 Skyline.

      Hey man looking pretty rad. Should have taken video this looks interesting.

        Thanks! I haven't taken any vids of it...but I just have to weld up the hangers tonight and the car is coming off the hoist tomorrow. Will have some photos of the entire setup on and off the car. It's been a while since I've had a customer that wanted a full SS exhaust system, so it was a delight to build this setup as he was very particular and I like that in a customer. I think there is approximately 25' of welding in the whole exhaust system, the entire 4" portion was all 15 pie cut sections and there was quite a few to weld in place.

        I should have completed pics up shortly.

          Just needs the muffler welded on.




          I'll post more pics when it's up on the car.

              Might not look like much, but the bracket was cut on the CNC table. Quicker and easier than doing it by hand.


              Lightly polished SS tip welded onto the muffler


              All done!

                  Where did you source the tube and what muffler is that? What engine is this behind?

                    Why all the pie cuts vs. elbows or bending? None available?

                      It's a Dynomax muffler, it was chosen by the customer. Tubing was sourced through a local vendor, they give me fairly good pricing for small quantity orders. The exhaust is built for an R32 Skyline that is being heavily upgraded.

                      Customer wanted that style, it was a lot of welding required but it was a lot of fun! Most systems I am building are with mandrel bends, they aren't difficult to source or cost (compared to labor cutting and welding). I honestly prefer pie cutting, if the customer can afford it.

                        Hi Mate, I own an R32 GTR Drag Car, just sold my 4" mandrel bend stainless exhaust and I purchased 4" titanium tubing 1mm wall and 4" titanium V band rings, I just wanted to know how u cut the angles on the tubing?? a cold saw or band saw?? and What angle did u use for your pie cuts cause that looks really really good,

                        Cheers Matt

                          Just saw this now so I might be a bit too late. I cut all the angles on the bandsaw. IIRC I'm pretty sure it'd be 15, that way you can stack up to 45 and do jogs with the cut tubing.

                          You can see more on my site: www.mint-design.ca

                            very nice work. 18 gauge? Also, what kind of settings were you using?

                            I'm sure the settings are more of a personal thing with tig, but i'm kind of new to welding, and this is the kind of stuff i want to do down the road.
