Looks, Sound, & Performance | MGS Custom Bikes True Dual Exhaust System
Better sound and more power are two things we hear guys asking for once they get their new bikes home. It seems that everyone out there is trying his or her hand at creating an exhaust system. Sometimes, the pipes we get our dirty little mitts on fall short on one thing or the other. Some have a great sound but have no gains or even rob the bike of power. Some may be able to add a few ponies to the bike but look like crap or sound bad. So whenever we hear “check out my pipes and get 15hp just by bolting them on,” we tend to find it hard to believe.
The same thing happened when Little Mike from MGS Custom Bikes called and said that the shop spent a lot of time perfecting a true dual exhaust system for the bagger market with a top-secret muffler design that will give a 15 percent gain in power and sounds as good as it looks. I told him it was hard to believe. To prove it, he sent over a dyno sheet from the last set that the shop installed on a customer’s Road Glide. The bike picked up more than 12hp and the fuel/air ratio was right on. We told Mike anyone could show off a dyno sheet with a few good pulls. He told me to come see it for myself, and later that week he was doing the same install on a ’10 Street Glide. He said if the pipes did not do what he said they would, he would fill my gas tank up and buy me the best dinner in the Antelope Valley. I figured why not? A free dinner is a free dinner.
MGS Custom Bikes is a Dyno-Tuning center, and been certified as the only Dyno-Tune center in the Antelope Valley so we knew this was going to be the real deal. Big Mike showed us the pipes and said that after installing and tuning other manufacturers’ pipes for years, he started to figure out the good and bad with exhaust systems. With all that knowledge of pipes and performance, he decided to build a set for his personal bike. After testing, the pipes made good power and sounded great. He eventually began making them to see if his customers would like them.
One cool thing about the True Dual is that the head pipe comes with both sizes of 02 bung ports: a set of 10mm ports for ’10 models and 5/8-inch ports for the older bikes. The pipes are available in show-quality chrome for $989.95 or black ceramic for $1,189.95. Big Mike also recommends that every bike get tuned once the pipes are installed to ensure it runs at its best. If you want longevity from your bike, it is more important to have it running with the best air-to-fuel mix than just getting big power numbers.
We started with Little Mike bringing the bike up to running temp on the dyno to get a base run and see just where the ’10 Street Glide was with the numbers. After two dyno runs, the SG squeezed out 60.1hp and 74.6 lb-ft of torque. Not bad; just about what we expected.
