oldschoolsdime92 Posted August 4, 2014 Report Share Posted August 4, 2014 I have an 08 wr250x that came with the power core4 muffler and the power bomb header. I also have the FMF tuner. As you all know its stupid loud. I have since swapped the stock exhaust system back on. It runs nicely with the tuner and the air box mods I have done with the stock exhaust, but its lost a little top end with the more restrictive exhaust. Is there anything out there that isn't so crazy loud and still flows well? Quote Link to comment Share on other sites More sharing options...

MidgetTodd Posted August 18, 2014 Report Share Posted August 18, 2014 Did you rewrap the FMF. Mine has same exhaust. You heard it, I don't think it's bad. I would keep it Quote Link to comment Share on other sites More sharing options...
oldschoolsdime92 Posted August 18, 2014 Author Report Share Posted August 18, 2014 I got her figured out. Went back to the stock header. Bike runs much better , and has better low to mid than with the PowerBomb. It knocked the noise down a bit also. Thanks for the input guys Quote Link to comment Share on other sites More sharing options...
