Reply With QuoteA friend of mine bends 4 inch for exhaust at a shop in Irwindale. I'll ask him where he goes.

After an exhast blowout in the standard black hoses I ran last year during the shakedown on the new boat yesterday, I swung by Schoor (thanks again for the tip Dave) and picked up some 4" OD Aluminum tube. None of the mufler guys in the South Bay that I have checked with can do it, so I figured I'd ask over here. Anyone know somebody that does large diameter tubing work?
Thanks,
Chris

Tell us more of what happened? You were using hoses that where a year old? and your replaceing it with the aluminum tube? Explain.....

Now is that not the biggest Rem. selection you have ever seen? Wish I could help with the bends.
Check out Precision Tube Bending (PTB). Where I work we bend a lot of CRES, titanium and Inconel tubing for aerospace apps, not muffler shop levels, and there is a major difference. We offload alum work to PTB.
They will likely have different bend radius tooling so give that some thought.
Also, do you know what alloy of aluminum you have ?
Not a muffler shop, but a shop that mandrel bends tubing. We do 4 inch exhaust and not many shops can bend tubing that size.

That was my 3rd trip out there. I actually just swung by yesterday on my way back from smellsomeore. We've already picked up a lot of T6 1/8 plate, some T6 barstock of various diameters and I imagine well be back soon http://free.***boat.net/ubb/smile.gif You can't beat $20 for 6.5' of T6 4" tube.
HB,
Here's the dealio. Last season I ran the motor minus Team G and bigger carb in my Dana with Stainless Marine 4" stainless risers connected to 4" ID straight hose from teague. I checked the things constantly worried that they might burn through, but never did. Those hoses are still in the Dana behind some stock Mercruiser manifolds at this point and are still fine. Now in the spectra, my 468 sits at a slightly different angle front to back which changed the geometry of the hose where it meets the riser. I bought new hose last week from Teague for the application due to low funds and not wanting to pony up for fabricated tubes at this point. When I took the boat (spectra) out yesterday for its shakedown under my ownership and power I noticed a change in exhaust tone half way around the lake. I poped the hatch only to see the top of the starboard hose spurting exhaust and water up onto the hatch. I headed for the ramp and after inspection found that the exhaust might have been hitting the rubber at too severe of an angle and thus heating to the point of a rupture. I checked the plugs and it's not running too lean as I first feared it might be. The other negative was that performance started droping through the floor on the way back to the dock due to water all over my coil and soaking the cap. I fired her up today after re-installing the MSD and everything is cool, so now I'm just waiting on a more permanent exhaust setup. I had the GPS with me yesterday but the tach was acting up because it doesn't like the MSD(fixed that with a MSD tach adapter) and I had too much going on to air it out and get a reading. Maybe Monday I'll have some numbers.
Talk to you guys later, and let me know if you get the info on that guy wsuwrhr.
Thanks,
Chris
Flat Broke, good to here everything else is ok. What do you think about a trip to Pryamid this Sunday? I should have the boat back from the interior shop, and I'm going to take her out for the first time since October. Hustler and maybe Party Cat will be there. Email me.

I just had to post this about Precision Tube Bending. The only bending they must do is their customers over the counter. I called them after not getting a response to my email and a real nice guy informed me that he could bend two pipes for about $800 dollars. Needless to say I rushed the boat down there as fast as I could... NOT. So got another local quote at 100 per side wich might turn out to be the ticket. That is unless I can find a way to rig a home made tube bender with a 4" mandrel out of a floor jack and one of the boat trailers http://free.***boat.net/ubb/smile.gif Back to the drawing board.

What about cutting and welding the tubes together in the angle you want. I know someone that can do it. He is the best!
Call or email me.
