Kleemann has been making products since well before the Crossfire was even thought up. We've had the chance to install some of the big companies' products on customers' cars and I can say that you pay for what you get.

We're doing a Kleemann headers and custom exhaust on an E55 and the welds and piping used are 10 times better then the last set of headers we installed from a smaller company.

As for the SC kits, yes they are expensive, but they are bolt on. One of my customers purchased an HPS kit for their M113 and spent more on modifying and fixing known issues then the kit cost just to get it to work.

Plus if you are really serious about getting Kleemann products give Corey a call and he'll work with you.
