Question Cobra Race Pro or S&S MK45s

Hey guys.. just got a 19 RGS and looking to get slip-ons.. been racking my head over two - Race Pro or MK45s - they both have a sound I like (deep and throaty rumble) - they both about same price (diff of 15 negligible bucks) - so questions is... in ones opinion or experience...
does one give better performance or is one better made? or why would YOU go with one over the other?

thanks in advance for inputs...

I like the look and deep sound of the Cobras.

I went with the MK45s over the High Outputs. that was my top 2 choices. I like Cobra mufflers. I have a set of 909s on the 19 Freewheeler and had a set on her 15 Freewheeler. But for the new RGS I want a performance muffler with great sound. Not just good sound. I think with any 4.5" muffler a bit of the bottom is lost. But not enough to matter. The look of the MK 45s is industrial to me. Well. The ones I opted for. There are 2 style end caps. And they come already on. So you have a choice with the MK45S. but the only difference it the look of the end cap.

The bell end on the Cobras is what makes them a no deal for me. To me it looks unnatural. Even if they had a better sound (to me) I would not put that pipe on my bike.

Here's the MK45S without the DB killers in.

MK45s all day, heard them up close , for me its the better sounding and looking muffler.

When all else fails, hell there is always beer!

I went with the Race Pro’s after listening to every muffler I could find a review on. I think they sound great and make me happy every time I fire it up. I also liked the wide mounting clamp. From as popular as the MK’s are on this forum though I doubt you could go wrong with them either.
