Delkevic muffler install on a Honda NC750X HD 1080p

Nice, I am looking to purchase Delkevic muffler!

I know the catalytic converter should handle the bulk of the needed back pressure. However did you find that you had some popping in the exhaust on deceleration. Its my belief the DB-KILLER yet offers additional backpressure even though minimal. I wanted to order the same unit. Have the same motorcycle except mine is not automatic.

Terry, what kind of foot pegs do you have ?

Hello from Friendly Vancouver Island! I have the exact same bike as you, (white even). I just bought it used with only 550km on it. Do you think the bike would work ok with a de-cat pipe on it? Would it mess with the fuel mapping do you think? Increase power a bit?

[@tcalof]

Sorry for the late reply. I believe a de-cat pipe would work fine. The O2 sensor will compensate for the any very slight change in exhaust gas volume. Power increase will be negligible, as the limiting factor is still intake and exhaust flow, currently constrained by the exhaust manifold. The big thing you're getting with a de-cat pipe is elimination of the cat converter, which means less weight, a lot less heat in front of the engine, and a deeper, more throaty exhaust sound in combination with a straight-through slip-on muffler like the Delkevic.

The BAFFLE is still in the muffler. All you removed is the DB KILLER. I hate people calling it a baffle when it is not.

[@tcalof]

I have to disagree with you. When the dB killer is removed, there is no restriction inside the muffler. You can see straight through from inlet to outlet. There is no more restriction to exhaust gas flow through the muffler once the dB killer is removed. To me, it's semantics. Whether you call the restriction in the muffler a dB killer or a baffle, they are one in the same in the Delervic muffler.

Hi Fred. Those are Knight Design billet aluminum pegs: www.knightdesignllc.com/Products/Motorcycle/Honda/NC750X/Honda-NC750X-Menu.html

Do you like that better than the GW?

[@tcalof]

Can't compare the 2 bikes in any way. They have totally different missions. For me personally, the GW was superb on the highway, especially with pillion. For anything else, it ranged from adequate to downright annoying, such as heavy city stop and go traffic. The NC is a jack of all trades, capable to do almost anything more than decently other than true off-road riding. However, it doesn't excel in any category. It ticks most of my boxes more than the GW ever did.

@@tcalof thanks for the update. I agree, stop and go traffic is a pain.
