5" exhaust

gnxtc2 · Aug 13, 2014

So I was bored yesterday.....went to the truck supply place and picked up:
- (1) 5" 90°
- (3) 5" 45s
- (1) 5' length of 5" pipe
- (1) 2' length of 5" pipe
- (1) 4"-5" adapter
- (2) 3' length of 3/8 rod

Cut out the old pipe and welded up some 5". I lowered the exhaust slightly in the back. When I raised the truck on the lift, the leaf springs would rest on the exhaust.

The 5" exhaust is much quieter than the 4" with a bullet muffler. Plus there is no drone.

My regret is not removing the stickers off the fitting prior to me installing it.

I do have a a 38 rear tank with the spare. I had to trim the rear tank skid plate at the corner.

Should I put a tip on it or leave it be?

Plus this my second time using the MIG welder.

What mig welder? 3.5" dp?

My friend left me his Miller 130 at my shop because he has no room for it. By the time I got to third fitting, the welds got better. I have to put the truck on the lift to clean up the welds on the hangers.

Don't know what you mean 3.5" DP ???

Can you take some closer pics of "hump" over the axle and where you cut the skid plate. I would like to compare this to my 5" diamond eye.

Wire feeder and a bottle of 75/25 was some of the best money I ever spent on tools. Easiest process to learn too. Post some closeups of the welds if you can. We'll be easy on you

I basically cut the corner off

Be nice....

My first weld

Gotta start somewhere. This was the second time I picked a MIG torch.

You were running a little cold at first but the last pick looks much better. Just remember make cursive e's tracing back into the leading edge of the puddle to get that stack of dimes look. The sound should be similar to bacon frying when you have it set just right. Which gas were you running? Looks like 75/25 due to the apparent lack of splatter. Good job and thanks for posting.

Thanks.

Yea when I first started, the wire feed was too fast and the temp too high. I slowed down the feed but kept the temp on high and it started to burn a hole through the pipe. I eventually turned down the temp. Once I did that, I actually heard the arc and it sounded "better".

Have the slightest clue on the gas.

This was my first project

Used the front wheel off a Toro lawn mower for my fence gate.

A little over $300. 5" gets expensive.

Nice McGyver job. I McGyver stuff all the time at work using reclaimed parts. I once made an enclosure/box using an employees old bed (sleeping) rails. Had to braze it since the stuff is heat treated and will become fairly brittle if welded.

If you like welding, you should try TGAW aluminum. There is no other process more therapeutic to me than tig welding aluminum. I just love the sound and how it flows. Not to mention you can fabricate things that weigh a fraction of what it would out of steel.
