Exhaust Question and Dilemma
I have a set of Hard Krome Strippers exhaust on my 2008 900 Custom. My bike also has a PCIIIusb and Hypercharger with K&N, it has been mapped from computer...no dyno (yet). I installed a pair of the Hard Kore Quiet Baffles from Smart Partz today and just took it for a ride through town, on the highway, up some big hills, and on some windy roads to see how they do.
Well the baffle inserts do make the overall sound of the bike lower, although I don't think the bike is much quieter. It seems to me that I don't have the same acceleration that I had before I installed them. It isn't bad, but I noticed on the hills that I couldn't accelerate and climb as before. I had a slight reduction in the "popping back" that I sometimes get, but nothing to get excited about. It also smells like my bike is now running richer, which is understandable, but I didn't think it was going to be quite so noticeable.
So this is my dilemma....I like the new sound over the former, higher treble bark. What I am concerned about is the mild decrease in acceleration and the richness that I have seemed to notice. Basically I'm not sure if I want or should keep them in since I don't know if the pros outweigh the cons. These baffle inserts have received good reviews from different forums that I have researched so that's why I'm a little perplexed.
Would adjusting my PCIII or having my bike dyno'ed help if I decided to keep these in? Also is there any concern to the motor by having these. The will be a pain to get out since I put a bead of silicone gasket maker around the end pipe (its what the instructions said).
