Barker's has been consistent in its quest to deliver the best 4-stroke exhaust systems available, and the new DRZ400 system is no exception. After testing the Barkers' system against the likes of Yoshimura, MRD, FMF, Pro-Circuit, and others on our dynamometer, nothing comes within striking distance of the Barkers' pipe, end of story.\u003c\/p\u003e\n\u003ch3\u003eBarker's Engineer Comments:\u003c\/h3\u003e\n\u003cp\u003eThe Suzuki DR-Z 400 has been on our radar for a long time. After years of success with the LTZ, we've come to realize that the DRZ400 motor, in particular, enjoys our reverse megaphone exhaust style. We were lucky enough to finally be given the opportunity to tackle this system with a customer's DR-Z, with a K\u0026amp;N filter being the only upgrade to the otherwise stock bike. \u003c\/p\u003e\n\u003cp\u003eAfter 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 \u003ca href=\"https:\/\/www.labaronspowersports.com\/\" title=\"Dyno Test Suzuki DR-Z 400\" rel=\"noopener noreferrer\" target=\"_blank\"\u003eLaBaron's Power Sports\u003c\/a\u003e by Alex Galeczka. \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0475\/8121\/files\/Copy_of_Barkers_vs._Stock_Tuned_with_Airbox_Mod_large.jpg?v=1526590301\" alt=\"Barker's Dyno Results Suzuki DR-Z 400\" style=\"display: block; margin-left: auto; margin-right: auto;\"\u003e\u003c\/p\u003e\n\u003cp\u003eAlex got right to work, clocking 30hp on the bike after being fully warmed up and putting down some pulls. After establishing the baseline runs on the DR-Z, we were ready to install our pipe and see where we sat. With our pipe alone and no tuning, we yielded 2hp gain peak; however, the Barker's DR-Z pipe pulled much farther into the revs and was a solid 3hp gain up in the higher RPMs. \u003c\/p\u003e\n\u003cp\u003eWe found that at idle and just off idle in the 0-20% throttle range, our pipe was running extremely lean; however, at wide open throttle, we were a bit too rich. After a few jets and shimming the needle, we saw even further gains. When we opened up the airbox by slotting the snorkel opening, the bike really came alive. After tuning and increasing the airflow, we achieved a solid 5hp gain. Even better, the gains were very broad and strong throughout the entire rpm range. 2nd gear wheelies became a breeze compared to stock!\u003c\/p\u003e\n\u003cp\u003eThe sound of the exhaust system with the turndown tip came out just right. It's a bit loud when on the throttle hard from behind, but at cruising, it quiets right down and would not be considered obnoxious for the rider. \u003c\/p\u003e\n\u003cp\u003eBeing new to the DR-Z crowd, we've got some reputation to build and hope to earn that as more and more people run and test the Barker's Z400 exhaust system. We look forward to testing on bigger builds, as our pipe is not just any stepped pipe into a muffler; with the reverse megaphone design, larger builds should yield even further gains. \u003c\/p\u003e","brand":"Barker's Exhaust","offers":[{"title":"Default Title","offer_id":28345718243415,"sku":"7MSE-DRZ400-SE-00","price":799.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0475\/8121\/products\/Barkers-Suzuki-DRZ400-Full-Exhaust.JPG?v=1760206091"},{"product_id":"barkers-exhaust-usa-tag","title":"Barker's Exhaust USA Tag","description":"\u003cp\u003eEach Barker’s Exhaust USA tag is riveted directly to the muffler can—not a sticker—signifying in-house fabrication, quality control, and American manufacturing standards.\u003c\/p\u003e\n\u003cp\u003eDo you have one of our older exhaust systems?
