I am possibly looking into getting an aftermarket exhaust for my 700xx . However , sound is an issue and i want better performance with out an exhaust that puts out too many decibels or something that is extremely loud . I don't have a decibel meter so i am not sure what the stock decibel reading is but i wondered if anyone knows of or has an aftermarket exhaust that is under 95 decibels for there 700xx and if its worth it ? I didn't know if the performance gain is worth it by restricting the exhaust that much on an aftermarket pipe but noise is a issue in my area and i have to keep the decibels down to a respectful level . To me, if there isn't a huge performance gain with a low decibel exhaust system then i would stay with my stock one . I just wanted to know if anyone else has an exhaust like this and what there thoughts were on it performance and sound wise etc..

You guys can correct me if I'm wrong, but I spoke to Eric at EHSracing and he told me that the Barker full exhaust with the Quiet core still made good power, but runs at about 96dB. I went that route for when I ride at tracks and sites that require quieter exhaust levels. I haven't received the exhaust yet, but I believe that he knows best.

I seem to remember the Barker exhaust loses about 1-2 horsepower on top with the QC fitted.
I think with any slip on there is hardly a gain worth having compared to the price you pay for it. If it were me, I would spend the money on a PC3 and get a good map for a stock exhaust and UNI filter and drop a tooth on the front for more bottom end power. I want to say the most any slip on will give you is about 1hp at best.

I would be cool with staying with stock exhaust if a programmer would give me a little boost and also a better air filter set up . However , I think i could live with 96 decibels if i had too as well but i wouldn't want to be much over that and if the performance is minimial with that type of exhaust than i would stay with a stock set up .

Yes, the bike responds extremely well to modifications. When you open the intake and exhaust side of the engine, you'll notice a smoother power curve. Then you can throw in a dyno tune and really refine the power delivery. Once all that is done, you can chunk a 13 tooth sprocket in the mix and you'll think you have a new bike!! I have thoroughly enjoyed putting the small amount of mods on my XX, and I look forward to receiving my Barkers then having the head ported and polished.

Why is that? I have enjoyed the extra torque the 13 tooth has given me. I do not ride in too many places that allow me to open her up in fifth gear, so I never looked at the top speed change negatively. I may do that though, I was just wondering why you suggested it.

I also plan to go back to the 14t once I install my Barker full exhaust. Everything else is already here with the exception of my Elka shocks and they should get here today. Been raining for the last 8 weeks and have some down time to get things done. I did order the Barker exhaust with a ceramic coated head pipe and with both the quiet core and just the spark arrester so that I can change quickly and run wide open if I want and the area doesn't have the sound gestapo.

It's not about top speed. The Big3 with complete exhaust makes noteable gains in power. First may be to short for you with the 13t, It would be a matter of preference but seriously worth trying.

Not if you expect to do any sort of technical trails where spinning the tires could land you on your ass.

Well, I will one my Barkers comes in. I only had the TwoBros Slip on, but Uni, EHS lid and PCV. I actually have noticed that 1st is almost nonexistent. I only use it when trying to go up steep inclines or when I get bogged down in the mud and wet sand in the Comite where we usually ride. I believe that I will try the 14 tooth again. Thanks for the input, I never thougth about that.

Once I have the Barker's full exhaust, I will have the Big3 installed. I didn't count my previous set up as having the Big3 because I didn't have the full exhaust; I had a slip-on only. Before I began looking into it, I didn't realize that the stock header pipe was so small. That's why I opted for the slip-on only. I was trying to be a cheap ass! Now, once I install the new exhaust, I'll be rolling with the complete Big3. I may not have known exactly what you were asking in your previous post.
