Looking to see if anyone sells steel tapered tubing like used on the Lake Headers we all love. Would the Megaphone tips like Speedway & Summit sell be the same or too thin? I think they are 2-1/4"x4"x30".
Would also like to know. I was told once that there was a company making table legs that worked great, but they went out of business. There is a place that makes cones for this application, but they might be just stainless and if I recall they were a little on the pricey side.
I looked all over for nice, subtle off-t******lf cones for my rpu exhaust -- with no luck. I wound up going to the Van Bebber brothers in Santa Rosa, CA. They rolled and welded exactly what I needed: 1.625" at one end, 2.125" at the other, and 23 inches long. Great work, fast delivery, good price I felt for two totally custom cones. They're at 707-762-4528. The cone starts at the first port, then tapers up to the size of the side pipe:
Burns Stainless in Cost Mesa, California, has cones in either mild steel or 304 stainless at reasonable prices. They also have mandrel J- and U-bends in both materials. http://burnsstainless.com/Megaphones/megaphones.html
The best tubes to use are the driveshafts off of 1936 fords, not the outer torque tube. They have a very nice taper to them and the best part of it is that you are cutting up old ford parts.... These are a set that my friend made for his underpowered roadster...
If you want turn outs, get a 2-1/4" j-bend with a 24" straight leg. Cut a pie shaped wedge out on the back side starting at 1-1/2" at the open end down to where the bend starts. Place 4, S.S. hose clamps over the tube and draw the edges together. Tweek the seam with a hammer and a piece of round rod 'til it matches apiece of 1-5/8" tube. Weld the seam up. For the pipes between the header flange and the tapered tube, go to a muffler shop and get 8 pieces of 1-5/8" pipe with a 70 degree bend in them. Trim 'em to fit and weld up your header. Go to your parts store and pick up a 2-1/4", 2 or 3 bolt gasket before you fab the block off plate and it's flange. There are different spacings on the bolts so you need the gasket first.Use hi temp anti-seize on the bolts. You should end up with something like this:
I've bought the ones from Speedway and Cone Engineering. Both really good. Also seen guys make their own. Little work but it's possible.
And now a HAMB Alliance vendor! Check out discounts in Alliance section. Regular price for a 30" cone is only $30 in mild steel. Louver baffles now available too. Stainless cones also.
