Exhaust Mani Tubing Thickness
So I am getting ready to fabricate my own exhaust mani. I ordered a couple of mandrel j-bends. They came and they are paper thin. The guy at Jegs told me that they were 16ga, but I mic'd them an they are 18 gauge. My question is, what gauge do would you recomend to construct this bad boy. 18 is ridiculous and I think 16 might be a little thin. Any help will be much appriciated.
Thanks Nick |

We use Schedule 10 on all of our manifolds, its pretty thick ----, but has never cracked/broke on us. They are nice 90 degree bends to work with, and the price is great. 4.20 a piece, get like 8 of them and you can make yourself a pretty sweet manifold. Jeff |
Re:Exhaust Mani Tubing Thickness
I didnt even think of them. I have an account with them. That is very reasonable for stainless.
I am going to fabricate a manifold like this: (pic compliments of shitbird) http://www.zcbrothers.com/honda/mani.jpg I think I can get away with 4 90's with 2 short straigh pieces. Thanks for the info man. |
Re:Exhaust Mani Tubing Thickness
While on the topic, for the downpipe, what do you recomend?
Thanks Nick |
Re:Exhaust Mani Tubing Thickness
16 gauge is fine.. Mandrel U bends from Jcwhitney work great.

Re:Exhaust Mani Tubing Thickness
0.065 316L works awesome. 60,000 miles on my turbo manifold no cracks. Also using the right welding rods for joing the flange to the tubing helps. Use silicone bronze stianless rods for that. And use 316L rod for the tubes if possiable. Its low carbon status helkps with carbon crepping and also helps aviod cracks. If you head over to the burns stianless website the have ammassed awesome info on materials selection,
' Of course inconel is the best but my god who can afford it ferrari ? |
Re:Exhaust Mani Tubing Thickness
I use the Mcmaster 90's also but in 8 gauge, aka schedule 40. best ---- on the market.

Re:Exhaust Mani Tubing Thickness
I mostly see schedule 40 on TT v8 all custom setups. 16ga should be fine for DP. Can you take that 18ga back?

Re:Exhaust Mani Tubing Thickness
Jesus christ, schedual 40... you want the fucker bomb proof or something? scheudal 10 is pretty ------- hard to cut as it is. Not to mention you dont want the manifold to way 100lbs. :P
