Thanks guys, I have since started changing my combo on this car. I will release a full spread once it is completely done and tuned, but it has the words "Twins" involved. The current combo is a full bolt on e55 with a 50 shot. The car made 686rwhp/805rwtq on a Dynojet but was completely useless at the track.
I am hoping this next combo will have more top end and not so violent down low.
I thought about getting rid of my g8 and cobra to snag one of these.. but damn parts are out of control! I knew they wouldn't be cheap since its a mercedes but an american racing long tube non catted pipe exhaust is almost 3k QQ
