92 LS1 FM T76 Build
2.5" pipe aluminized steel exhaust pipe? If so, its never going to last for two reasons.
1. that manifold is stainless steel that you welded it to, Stainless steel an mild steel grow at different rates.
2. If its ehxaust tubing, it is way to thin to handle the heat cycles and stresses.
Just my opinion, hope it works for you.

I did not know that...I hope your not right...But oh well...I will just have to see how long it will last and redo it if it doesn't work....Its a learning experience too.

Well first off, Turbo piping gets MUCH hotter than most NA applications. Its not uncommon for the hot side piping to get almost cherry just after a dyno pull, much less a drag strip or street race.
That extra heat combined with the growth rates and then factor in the dissimilar metals and that the MIG wire is most likly the wrong filler material for stainless steel... There are quite a few problems here.

I've got everything done except for finishing up the exhaust and having the car tuned....Just installed my Racetronix pump and harness tonight..Everything seems to be working good.
