Hey sorry about the sickness guys. I just got over the flu myself.
Hope everyone gets better!
Anyway, I was in home depot and I figured I'd get that chromed copper tubing while I was there and if it didn't work, oh well... it cost me $3 for a straight tube and two elbows, which the lady threw in for free because they didn't have tags on em. I also checked on that heatless solder. I found some called 'QuikSteel', it's made for exhaust and muffler patching, and it's rated for 500 degrees farenheit. Is 500 good enough? I read what you said about the tube diameter so the first section of pipe is 1 1/4" and the last is 1 1/2" to make sure I get good power through all RPMs. I wanted to do an under-frame exhaust with a side exit, but my front axle is too low unless I had the pipe come out the side of the engine compartment and under the foot hold. I don't know... theres too many possibilities
If it works then I'll try and post some pics on here. If not, then it's straight to G-Team I go lol!
