I am looking for a factory exhaust manifold/header to fit a 1999 Diablo VT. I understand that any manifold from a 1995 1/2 + will fit. The part number is 004435457. I am looking for the passenger side rear manifold.
Please email or call if you have one you want to sell.
Thanks

I have friend, that has a 95 1/, he installed a new Larini system because 1 of his manifolds did what yours did. I do not know which one, but wrote to him, to see if the manifold you want is still good and will he sell it.

Thanks Chad. Still hoping just to replace the one with a used, if not leaning toward your quicksilver set. I am not a great mechanic and dont like hanging upside down for 2 hours to get them out so prefer to just replace one than all 4.
Do you think that you pick up much in HP if go aftermarket?
cheers

Not really, because the aftermarket system is designed just like your stock system.
Now I am sure someone will jump in and say different, but having been in the racing business for over 50 years and won a ton of races and built many a race and stock engine, I feel I kinda know what I am talking about.

Now if you want to build a totally new exhaust system designed to make more HP that can be done, but we are talking about $5000 or more thousand dollars for a custom system.
