| Post subject: | Custom Exhaust Build Questions |
Im looking into building an aftermarket exhaust. I have the tools/welders/and material at hand to use at my convenience. I was going to ask and see what the best thickness and best material to use would be? And what are some of the things i should steer away from and what i should look at doing? I plan on adding some sort of baffle in it, just unsure of the best way to approach it. Any advise helps! Thanks, Laiken P.S.- I already have some plans and designs draw up and what i think ill like. No numbers and measurements yet, but ive got the time to take it piece by piece and build it as i go.. |

I'm just about finished mine. I'm using 4"schedule 10 for the muffler. I have 1.5" SS 16ga tubing for headers. I also have them to slip fit like the MM to prevent cracking and give some room for thermal expansion. No baffles in mine. ComPletely open. I have two 1.5" outlets. My outlet pipe extends all the way inside the 4" until about 1/2" from the other side. Read that this helps with backfiring ( maybe it does, maybe it doesn't). Should have it all welded possibly this weekend. |

Looked to purchase but didn't find any. Decided to cut my own out. Took the new gasket, traced it out on some SS 1/4" plate and cut it out with my plasma. Cleaned them up and ready to weld. 1.5" SS came from Columbia mandrel. |

Yea I'm probably gunna cut my own out as well! Just seems easier to do if you have the tool and time to do it. Saves money too! |

So your welding stainless with straight argon, how does it look and weld. |

Going to tig it. Tig welding SS I use 100% argon. Mig welding SS I use tri mix. Don't have any alloy wire for my mig and would rather tig it because it's thin wall pipe and tubing. |

Did you get a builder kit? 1.5 ss? I have been debating on building a custom or gutting a stock stainless. May try both and see what I like better. Sent by my RAZR Maxx via Tapatalk |

From my experience having modified the stock stainless muffler and fixed it twice since then I'm starting to wonder if I should have just cut it off at the headers! I been chasing cracks almost everywhere there was a factory weld. |
