New preparation on Superleggera 530

[Vince_1972]

as part of my preparation, I seek a titanium exhaust system with the best performance and valves.

Here's what I found:
Kline Innovation -> sound great, but low gain (10-12 hp) (email with the company)--> my favorite for the sound but the gain is very low http://www.kline-innovation.com/wp-c...21-768x500.jpg

TiTek Innovations | TiTek Innovations: Leader in Titanium Exhausts -> sound nice, announced gain: 30HP and 22TQ Gain (found on vividracing)(I saw the dyno curve)http://cdn.shopify.com/s/files/1/076...g?v=1425667369

iPE (Innotech Performance Exhaust) - The best build Valvetronic exhaust system in the world for supercars. -> sound great, I have not found gains announcedhttp://www.ipe-f1.com/upload/images/_MG_6950.jpg

Frequency Intelligent Exhaust - Valvetronic Technology for Supercars -> sound great, gains announced 5-10% (email with the company)http://www.fi-exhaust.com/images/pro...rlymodel_1.jpg

Fluid MotorUnion --> sound nice, announced gain: +30HP and 25TQ Gain (I saw the dyno curve)https://scontent.xx.fbcdn.net/hphoto...7d&oe=55A5E023

I really need help!

If someone with an opinion or experience or something to offer me that would be good!

Thank you!
