Guys,
I sweated over the perfect exhaust for about 2 years. I did a lot of research, weighed the pros and cons and finally made the decision to go with the TUBI. Had it installed with a DC header, and added the Dali chip. The HP improvement was noticeable. Oddly the addition of the Dali chip seemed to somehow make the engine run smoother. As far as the sound is concerned I am extremely pleased. The quality of the TUBI is phenominal. The tips are like no other aftermarket exhaust. Also a TUBI exhaust will probably add to the cars value because of its exclusivity. And those Italians really do know how to make an engine sing sweetly!!!
