Exhaust upgrade suggestions
Hi guys, I'm enjoying the heck out of my 2009 XK but I hate the stock exhaust! I've got a wild hair up my rear and will get rid of the stock exhaust. My #1 goal is performance... but I don't want it to be annoying. I am thinking of going with Magna Flow muffler up front and straight pipe all the way to the rear. I am thinking about adding a X pipe just rear of the muffler. Any suggestions? Pro's Con's?

I too am thinking of upgrading the exhaust on my 4.2 N/A convertible. I spoke with Chris at Mina and I will be buying one sometime soon. From what Chris told me it's best to stick with a 2.25" pipe on the aftermarket exhaust. That's the diameter size on the Mina. It'll match the size of the stock pipes which in turn will not have an adverse effect on the car's low end torque.

I had Magnaflow mufflers swapped for the OEM muffler and it was horrible. The back pressure dropped too low and the car was a dog. Worst money spent. Threw the mufflers in the dumpster and put the old muffler back on.
If you want to change out the exhaust, go for an engineered system. Larini is one of the best, regardless the marque.

Once I move out to Palm Springs then that's another story. Miles of open road begs for an "R" but again. here in So Cal not so much. Enjoy your new ride!

A catback exhaust is the only mod I suggested. An X-pipe and free flowing cats are additional mods. So, with just a catback exhaust the only gain is sound. The horsepower gains alone are negligible.

I contacted Larini to see if they offered an exhaust for my XK 4.2. They responded promptly and have an awesome system avail. $1100 + shipping for the muffler, 30 days lead time to construct. Club Sports Center section is an additional $600 . They guarantee a noticeable torque feel with a flat torque band across the power curve. I’m sold!
