As stated from Ruf Auto Centre website the 600hp turbo upgrade gets, "Fine tuned engine electronics, sports air filter, conversion of exhaust with 4 round 76 mm end tips and sports catalytic converters, RUF VTG turbo chargers, stronger clutch."
So what's the exhaust conversion? Does it include manifolds? I don't mean to hate, but this whole kit seems a little lack luster for 45k.
I'm just throwing it out there, because I was comparing kits for fun and I didn't know.

 

The easiest thing to do is just call or email Wayne Corley at Ruf in Dallas. The 600 hp kit includes everything you just said...no exhaust manifolds. I also guarantee you the price is now higher than $45K due to the weak dollar. While pricey, you get a 1 year warranty, extraordinary service, and very good integration...as well as the "Ruf" label. It will add value when you trade it in the future. But have no misconceptions...the myth of Ruf cars "understating" their hp is not true. 600 hp means 600h hp.

 

Fine by me. I have yet to meet a tuner that doesn't overstate their claims. I used to use Dinan products on my BMW until my friend's bone stock M3 walked on me. If Ruf's 600hp is 600hp then I'll be happy! Thanks for the info.
