What do you guys estimate a Tubi will cost on my '84 308 GTSi QV Euro?? I would really like to add one because i've heard it's hella loud. Also, how much HP will it add (if any)? Thanks.
I think the tubi is about $2500. I've seen claims or 10 hp, and claims of lost hp. That usually means that you should expect about zero if the engine is tuned before and after. It is a lot light though, so that counts for a little I guess.
