True duals?&nbsp; Or maybe a 2-1 that you can build onto at a later date? You can ask on one of the many social media pages, and you will generally find that everyone has their favorite. Mostly because they run that particular system on their bike, and think everyone else should as well. It can be a huge swamp of information to wade through.<\/p>\n\n\n\n<p>First and foremost, as a dyno tuner I can tell you SOUND DOES NOT EQUAL PERFORMANCE!!!<\/p>\n\n\n\n<p>You might be tempted to get those muffs that have cool names that sound like they came from the night of the living dead. I have seen some of those come into my dyno shop that are nothing but a chrome shell with a straight piece of pipe running through them. And the reality is they don\u2019t work worth a darn.

Dyno tuners have seen just about everything out there and know what works and what doesn\u2019t, and the information garnered from them can be priceless. If you have local dyno tuner you work with, get their advice.<\/p>\n\n\n\n<p>Some advice I give my customers is make your choice based on looks, sure, but more importantly sound and performance.&nbsp;Too loud can not only make your ride less enjoyable but have the possibility of hearing damage over the long haul. For performance, a 2-1 will generally give a better torque curve on a street bike than a true dual system.&nbsp;If using a true dual setup, those that have some type of collector will work best. These are generally called 2-1-2 systems and can work very well when paired with appropriate mufflers. A couple that come to mind are the S&amp;S Power tune dual or the V&amp;H Power dual. One thing to remember is the exhaust is just part of a total combination of performance parts.<\/p>\n\n\n\n<p>To help you narrow down your options, you can simply pop up the <a href=\"https:\/\/www.denniskirk.com\/exhaust\" target=\"_blank\" rel=\"noreferrer noopener\">Dennis Kirk Exhaust Finder<\/a>. This will give you many systems that fit your ride from great brands like <a href=\"https:\/\/www.denniskirk.com\/cobra\" target=\"_blank\" rel=\"noreferrer noopener\">Cobra<\/a>, <a href=\"https:\/\/www.denniskirk.com\/rinehart\" target=\"_blank\" rel=\"noreferrer noopener\">Rinehart<\/a>, <a href=\"https:\/\/www.denniskirk.com\/s-and-s-cycle\" target=\"_blank\" rel=\"noreferrer noopener\">S&amp;S<\/a>, <a href=\"https:\/\/www.denniskirk.com\/vance-and-hines\" target=\"_blank\" rel=\"noreferrer noopener\">Vance &amp; Hines<\/a>, <a href=\"https:\/\/www.denniskirk.com\/freedom-performance\" target=\"_blank\" rel=\"noreferrer noopener\">Freedom Performance<\/a> and <a href=\"https:\/\/www.denniskirk.com\/supertrapp\" target=\"_blank\" rel=\"noreferrer noopener\">Supertrapp<\/a>, to name a few. All available with extremely quick shipping as well as great customer service.<\/p>\n\n\n\n<p>So once you have a few choices in mind; maybe your buddy\u2019s bike had exactly the sound you were looking for, and you choose that route\u2014but not many riders are conformists; or you took the advice of your shop; maybe you used the Exhaust Finder. Whatever the case, now that you have the high flow air cleaner and exhaust picked out you will need to address the next, and most important question: how are you going to get the proper air fuel ratio and timing for the mods you have done? That\u2019s a subject for next time.<\/p>\n\n\n\n<p>Don\u2019t forget, support your local independent motorcycle shop!<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:10%\"><\/div>\n<\/div>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Once you\u2019ve narrowed down your Air Cleaner choices, it\u2019s time to address the exhaust for your Stage One upgrade.
