i still have the undertray on the engine and personally i would prefer to keep it on just for added protection with the miles that im doing
 
frankly you get what you pay for, yes Piper is slightly more expensive but they are the best systems on the market, the quality of the system is far better than milltek when you look at the 2 side by side, the turbo backs have got wider bore downpipes, and the sound is better, obviously time will tell how they last but since you get a lifetime guarentee with Piper rather than the 2yrs years you get with Milltek frankly, it was a no brainer.

Miltek do lifetime warranty on their cat back systems, its the downpipe which is only covered for two years but that seems pretty fair and didnt put me off getting a full miltek.
As long as you are the original purchaser, cat-back exhaust systems are covered by a lifetime anti-corrosion and manufacturing defect warranty and hi-flow sports catalysts and downpipes are covered by a 2 year or 80,000km warranty.
