Zuber,

Any chance you can give us a sound clip of the Q4's with and without the spark arrester? That would be much appreciated. Ray

Remus Carbon, Best mod I ever did. I had a buddy on a Harley insist on me leading just because He liked to hear the bike so much.

I've had Arkra's and was disapointed with them. With the baffles in the sound is not much different from stock, the advantage being weight reduction and looks. Baffles out, they are too loud.

Now I am running a pair of titanium scorpions. They looks great, sound great (more grunt than ackra's with baffles in) and baffles out - obscene.

They are also cheaper than ackras. Only problem is, not sure you can buy them anymore.

Question Akrapovic Evo's or FMF Q4's - Or Something Better??

I'm trying to decide what exhaust system to install to both increase the performance BUT mainly reduce the weight and heat of the system on a 2010 990. Any suggestions? I would like to see if anyone can give me the actual weight of the different systems - or at least a link to were I can find them. My main goal is to reduce the weight as much as possible, plus get rid of the heat the stock cans produce. Durability issues also if any?

I know the 990 doesn't really need the performance boost (hell, it's a rocket as it stands) and I'm not into a "real" loud exhaust systems - but a good throaty, deep sounding one I think is really nice, ok sexy, I said it. And I'm sure exhaust systems are like tires, everyone has their favorites and opinions so if anyone can maybe put the systems into a best (no matter what) to most practical list with the pluses and minuses of each that would be great.

I'm not sure if I really need the spark arrestor that the FMF Q4's have even thou I plan on doing the TAT and Continental Divide Ride, and I'm pretty sure the Akra Evo's are street legal so please let me know if these 2 trails require the sparks arrestor or if I'll get into trouble for running the Akra's.

PLUS - ARE THE AKRAPOVIC EVO'S REALLY WORTH THAT MUCH MONEY???

FWIW, I installed a set of FMF Q4's on my recently aquired 06 950 A. I found them just a tad too loud. Others had posted a modification to them by installing a copper 1" - 3/4" reducer available at any hardware/plumbing store. They go over the screen from the inside with the 1" end first. I drilled through the insert and the reducer 180 degrees apart and safety wired them in place. As previously reported, it took some of the "bark" out of the sound and made the engine more responsive off of the bottom. All-in-all, I'm very happy with both the FMF Q4's and the simple reducer mod. I still have the stock jetting, filter and smog equip.

Do you have your reducers in on this? I have the can reducer in on mine, the only time it gets just a little raw is heavy twisting going up a hill, otherwise I can sneak around without too much attention.

jup, got the sparkcone and the orig.db-killer (bottom black smoked) as well as the cat in it - got also an other db-killer (for the us-market) which reduces the sound to almost original

It looks like we have about the same two types of threads going at the same time. 950 Adventure Exhaust/Muffler Poll and Which Akrapovic Exhaust System?

Hopefully we get to the bottom of this debate - ya right?

Akro VS FMF

"If it's too loud you're too old"

OK, so I can't imagine they're as loud as a Sportster with straight pipes.

Racing motocross back in the 80's, I loved the sound of a big 4-stroke with a good muffler. You could hear it a mile away.
Which is louder...Akro without insert or FMF Q4?
I think the weight is about the same (with in a pound or so) 5lbs.

"Loud pipes save lives"

Picking up an 04 950ADV next week with stock cans.

Heat Issues

I've heard how there is quite a bit of heat from the stock exhaust, especially for the passenger. What's the concensus of the GPR 2-1 set-up VS twin cans on the stock pipes? It looks like the can is further away from the passsenger, but is there much heat down around the right passenger peg?

What pipe?

My 950 has Leos. I have removed the SAS crap, and lowered the main clips 2 notches as per suggestions. It ran pretty good, and they Leos save a boat load of weight, don't heat up, and sound really nice (not too loud with baffles in).

But it never ran really well until I put these in: http://www.advmachines.com/mobile/default.aspx#P18

Now it runs so unbelievably sweet....
