I am about to order this kit and was just wondering if i can use my current RMR catback and UR cat delete or if i need to buy an AMS unit?

Also is there any dyno plots, or track results on this kit? What boost was run to acheive your results? I havent seen much info on it, and i am thinking the 35r is overkill for my 375whp on 93 and 425 whp on c16 goal..

Also if there are any owners out there how do you like it? Do you regret chosing it over the 35r?

Thanks
Dave
