so ive decided i want to go with a single 7 inch stack, i dont want to spend 500 dollars for it so does any one know where i can find 7 inch aluminum tube at. i live in the CA bay area and i dont know if its me but ive been looking online and cant find anywhere that sells 7" tube!

 

Go to a place that does tractor trailer exhaust and purchase some stuff from them. If it was me I would purchase all the goodies myself to rig it up into the bed and then purchase a Grand Rock to top it off.

 

yea thats what i was going to do but im going to go for the blacked out look and grand rock stacks are 250 bucks. and im going to get it painted black so it would be a waist to cover that chrome

 

If you would like to have a bull hauler style stack, you could use a stack off a '05 938 Caterpillar frontend loader, and if you would want a miter, just cut through the weld on the tip, plus it comes with the heat resitant flat black finish, and they cost around 70 bucks per each(when i purchased some), and they are about 36" long. And the diameter is 6" though......
But you can also use one off the heating chamber off a A5000 series cat road paving machine. The dimensions are 11" diameter by 40" tall and it too is a bull hauler style. They cost around 120 a piece though.

 

i dont know wut part of the bay your from but allen steel company should have it for you. i'll ask my muffler shop friend if he can get some.

 

my bare metal grand rock stack was alot cheaper then that...you should be able to get one from any GR dealer...

 

Do you have any local big rig junkyards near you? Might try there.

 

i ended up with a five inch turn out, not what i was looking for, it looks sweet but im still wanting to do a 7 inch mitre so if anyone knows anybody who is selling one let me know!!!

 

I went to the parts/service counter at the local international dealer. They got me 36" of 6" unpolished exhaust tube for like 20 bucks, another 15 or so for the 5-6" adapter and all i have to do is paint it and make the cut at the top, its been sitting for months tho...just need motivation haha
