Important Notes: If you're running the stock rear turn signals in their stock location, the straight billet tip option may melt them. In this case, the turn-down tip is the better option. Also, if you order the muffler in black and the muffler tip in the same color, both will be powder coated so that they match perfectly. Silver muffler orders with billet tip colors are anodized.

Comments from Barker's Performance

The Suzuki DR-Z 400 has been on our radar for a long time. After years of success with the LTZ, we've known that the Z400 motor really likes our reverse megaphone exhaust style. We were lucky enough to finally be given the opportunity to tackle this system with a customer's 2016 DR-Z, with a K&N filter being the only upgrade to the otherwise stock bike. 

After spending some time developing a prototype that suited the look and feel we were going for, we felt confident heading to the dyno. Testing was completed at LaBaron's Powersports by Alex Galeczka. 

Quote from Alex Galeczka, DynoJet Professional Tuner

In terms of power delivery, overall performance, and quality of construction, Barker's Exhaust is the clear winner in the DRZ400 exhaust system shootout. Barker's has been consistent in their quest to deliver the best 4 stroke exhaust systems money can buy, and the new DRZ400 system is no exception. After testing the Barker's system against the likes of Yoshimura, MRD, FMF, Pro-Circuit and others on our dynamometer, nothing comes within striking distance of the Barker's pipe, end of story.
