I borrowed a CEN GST 7.7 tuned pipe to see how well it would work with the new HPI K5.9 engine that I have installed in my Savage X SS. All I can say is WOW! The CEN pipe outperforms the stock HPI polished pipe (included with the X SS and XL trucks)in every way! The K5.9 had better bottom end punch and it also hit higher peak RPM's. It ran cooler with the CEN pipe also, making it easier to tune.

  • Ok just wanted to add that I installed CEN pipe yesterday on my 5.9 and WOW amazing difference.  I left the cone in but took baffle out for max performance. You notice the difference before you touch the throttle (Alot deeper, cooler starting engine). I have also tried the RD Logics quad stinger, stock 5.9 polished, ofna 086. I will stick to the CEN.

  • That's interesting. Does it perform better than the HPI pipe?

  • Very well the pipe Cen... also on F4.6 !!!

    Thanks !!!

  • I wouldn't recommend it unless you have upgraded to the newer 4 gear differentials. You could always upgrade them after they break though.
