I'm running a catless stock headpipe with unbaffled stock mufflers. Tuned with V&H Fp3 and absolutely love it. Still running in autotune mode and probably will for the summer to collect enough information to flash.

Never mind. Wrong forum. Lol. Didnt read it was a M8. Duh

I posted a dyno with stage 4 with stock head pipe and with fuel moto head pipe installed

I have a stage 3 with Fuel Moto head pipe (no cat). Made all the difference in the world!

My tuner said the only reason he could make my CFR's work was because I had the FM head pipe. Of course many other mufflers would still work better down low but I had a personal sentimental reason for running them. He sees all of the head pipes out there and he said Fuel Moto and Fullsac in his opinion are the best for whatever that is worth.

It's  called TCI Tunable Collector Insert

No adjustment to intake or air cleaner?  Just the header, mufflers and FP3? 

On my Slim with 103" I did V&H slip-ons (removes the in muffler cat), air cleaner and FP3 and it was like a whole new bike.  Great results.  I was just hoping to not do the header on my new CVO SG. 

I put FullSac headers on my Limited with 103" and it was great, but it's a lot more work.  Of course on that one we did the air cleaner, D&D Slash downs, put Andrews cams in it and had it dyno'ed also.
