I wrote this brief review a while back (on a 2001 XKR):
Overall I am quite happy with the product. Fit and finish is very good, and the sound really makes these cars sound a lot sportier, without being obnoxiously loud. It adds a lot to the experience of driving these cars for me. I also like the look of the large pollished ovals.
I got a small mileage boost (1/2 -1 mpg) and the car feeling a bit peppier, but nothing dramatic. If you look under the car, the original exhaust is haevily constricted through multiple bands and compressed areas, and these completely resolve that issue and removed two of the five silencers.
The only very minor issues is that somewhat light duty hose clamps are provided for attachment to the stock exhausts, whereas the other muffler clamps provided are very heavy duty. (they are all staniless, BTW). Just do not overtorque these...I had no actual problem and they seem to get the job done. The other issue is that Mina recommends the pipes be mounted tight up against the 'X" reinforcements in the rear (for maximum clearance). It seems kind of unusual that the pipe actually contacts the chassis in this way, and I have heard reports of vibration if these are not mounted tight to the chassis. Again, I had no actual vibration problem, and they can be tightened up against the chassis by bending the hangers slightly if necessary or by insulating the 'X' reinforcement in the contact area with a short length of 3/4" heater hose. Also no instructions are provided, so talk to Chris at Mina if you need to, or I can help you too.
