Yeah the exhaust is going to be rather unique, it is going to be dual 3inch, but the pipes are going to run under the transmission and the xpipe is going right under the crossmember. Below is the tranny crossmember i built when i built my 4l80. I designed it for this sole purpose. The exhaust pipes will exit before the tires for now. When the 4 link is done i want to run duals out the back like i have it now, exiting in the corners.

I need to learn how to weld. .... I need more garage space......

Do you have a pipe bender or just buying all the curves and welding it all together?

I love welding. I am not the best but i am decent... The guy that was helping the last few days, i was teaching him to weld for the first time... He actually did pretty good for his first time...

I wish i had a bender... I usually buy 90* bend and cut them to the angle i want... Usually i cut all the 90*s into 45* and piece everything together that way...

ya it just seems like with a welder and some time and creativity the options are endless.

I have never touched a welder but a friend of mine was a welder on the USS Ronald Reagan for 5 years and just bought a welder for home so hoping I can learn one of these days. When I finally get my LT's and all that I will get a chance to learn and have him help me weld it all up.


What was your reason for doing true dual over a single??

Also on a side note, I did not adjust anything on my tune and the trims were still +/- 3%.... I left the IFR table the same, because i did not hook up the vacuum reference... After i swap out the exhaust and need to retune it I will hook up the vacuum reference line and adjust the IFR table for return style. I thought that was worth noting.

Learning to weld and owning a welder is great! Honestly i have no clue on what i would do if i did not have one... Metal is one of the easiest things to work with. I learned to weld working in an exhaust shop during college, and i also welded when i worked in a body shop... Actually this is my first time welding stuff this thick... 3/16 is the thickest i have tried to weld with this welder. It is a lincoln 175 (220 volt), it is not as nice as a miller but it works for me. Eventually a tig will be sitting next to it


About the dual 3inch, i dunno, just something different, plus i have all that room underneath, might as well use it right??
