I am totally on the fence here. the M-7 is basically about the same price as the power core (m-7 is like 20 dollars cheaper) from listening to the youtube vids they sound basically about the same. Although hard to really tell from the vid.
I would be using them as a slip on. The stock exhaust tip is just way to quite. I will be riding on the road some times to get form trail here and trail there. I dont want something window shattering..

Any thoughts on which one is better over the other? I was leaning torwards the FMF power core but , could save the 20 dollars and get the M-7.

 

I put the FMF Q4 on my bike. I also took the lid off of the air box. I am very happy with the results. It was under 320.00 on Amazon with free shipping.
My .02 worth.

 

Thanks for the reply!

 

Don't know about TB vs PC4 .

But I can assure you there are louder slipons out there, compared to the PC4.

My DGR was much louder than my PC4.

Only member comments about the TB is that they are LOUD !

 

IT is a tough choice.. Would be nice if I could just buy both lol.. I am trying to avoid being to loud. Sounds like the powercore might be the right choice over the TB. Also in that same price range is the Q4 or powercore and they both sound about the same in the vids. Read comments that the Q4 is little softer then the power core. Be nice if they all had db ranges to compare against.

 

I fine the Q4 to be perfect. Nice thump without being too loud. Way louder then stock. Sometimes I still think to buy the quiet core insert for exploring days.

maybe this video I found will help.

Q4 fan here.
My first aftermarket silencer was an HMF. It was loud. Annoying. It had to go.

 

Thanks all for the info big help. That vid was great with the db rating. Reading some of the details about it made it seem like it was going to be little to quite but, reading the posts its sounds like it is going to be perfect! I pulled the trigger and bought it along with a few other upgrades. I'll post some before and after pics once the major new cleaning is done and upgrades installed.

 

I know you've already purchased... but for future searchers, I'll put in another thumbs-up for the Q4.

 

Thanks that helps. At least its reassuring that its the correct choice.. This week end is my first trail riding. I was really hoping it would be delivered before the first ride but, looks like next week it will be here along with the other goodies I bought.
I keep hitting the tracking number like its going to change min by min.
