With my pumped-up R 560, I drive heavy loads every day in the mountains near Trento. Two years ago a colleague of mine, who had mounted the Collerocks, was happy with them and recommended them to me. I couldn't believe it when I installed them: the truck didn't vent any more, the engine sang like a violin and I was happy. After years of suffering, finally someone has solved the problem of these damn headers. Thanks Collerock for existing.

It was years that I was throwing away money on junk manifolds that after a few months were destroyed, absolute crap. My Scania R580 is nicely pumped up, I like it that way, but, as you know, the horsepower eats the manifolds. Today, with Collerock manifolds, I have solved all my problems. Collerock is a name, a guarantee, try them and you won't regret it.

My Scania 164 580 has a lot of horsepower and this forced me to change the manifolds every 4 months...a bloodbath. Then I saw these Collerock headers on facebook and decided to buy them. Since I mounted the Collerock headers I have solved all the problems. No more vents, no more money wasted in the workshop. Now I'm also saving a lot of money on diesel and the engine runs like a dream, you know why? Because I don't drive with the manifolds blowing like I used to. Thanks Collerock!!!

I met Collerock 2 years ago while I was on facebook and I immediately called. I felt that my Scania R500 needed Collerock collectors and so I fitted them. After a year I decided to pump the truck and luckily I had the Collerocks because otherwise, by now, I was already in the workshop mounting the usual cast iron manifolds. Now I do the climbs in France and Belgium without sparing myself.
