how to build a 4-1 collector(hp-style)
 

Me and my bro are working on my new mani.

just wanna share it with you guys.

for now i have pics of the collector that we did a few days ago. this is all home made ---- and done in our garage.

Step 1:

cut the sched 40 pipes in 1' lengths and placed it in the band saw.

step 4:

if you measured the 90' cuts well you shoudnt have any problem joining the 2 halves of the collector.
if you have a gap on the middle. you can use the chop saw to level both surfaces.

spot them togeteher until no gaps the weld together.

Must be nice to have that stuff in your garage. how long has your bro been welding the welds look pretty good :y

less than a year. its just a hobby ;)

Re: how to build a 4-1 collector(hp-style)
 

you wasted a shitload of pipe right there. 1 foot length is crazy.

you should be able to start with a 5 inch piece and cut it where youll not even need to cut anything afterward with a chopsaw. youll cut 6 inches or more off that collector before its even wide enough to fit the t3 flange.

thats 24 inches of wasted pipe. 24 inches of pipe is another whole collector if done right.

noobs, pay no attention to this post.

also, when you welded the inside of the collector, you only welded 2 of the 4 sides. so you might as well have not welded any of them.

maybe tomorrow ill make a how to make a real collector on a bandsaw post.
