Your thoughts on 04 V92 TC performance upgrade...

2004 V92 TC.
I have now read a fair amount of the threads here on beefing up the power output on my TC with regards to fuel control, Airfilter, and Exhaust. I ride daily about 60 miles round trip to work/back, 2up on weekends 1/2 the time (not so much in winter hehe) and don't want to loose alot of my lower end torque for the mountain areas. If someone could check me on what I am planning to do performance wise and let me know if I am going in the right direction or not it would be great:

K&N Airfilter

Dynojet Power Command III PN 938-511

I have stock exhaust, am ok with the sound but do feel that the backpressure is choking it out when I lay into it. If what I read is right, I plan on pulling the pipes drilling the center and punching 6 .5 holes to improve flow. I am doing this for performance, not louder pipes. I have not been able to exactly tell if this garage mod is for my exhaust or not so I am including the link, a pic and the PN of my pipes. If someone has the common name for them that would be great too!

This forum has been a great asset and looking forward to the input!

The guy I got mine from told me he had the mufflers opened up and a K&N filter.Had the system checked and the factory specs were where the computer can fix it without a power comander or remaping.Been like this for 20000 miles and runs great sounds great too.

Agreed, if all you are doing is a K&N filter and more open slip-on pipes all you will need is a Stage1 Victory calibration. No need to spend all that money on a PC and dyno tune.

Thanks for the info guys. Will be doing this once weather finally moves in to stay a while. One question, what type of pipes are these and just making sure before I pull them that I should knock out the center and drill the 6 1/2" holes on this style. Thanks again!

Updated: I pulled one slip-on this afternoon because I couldn't figure out if the baffle seemed to only be about 8 inches long where was the plug I was supposed to knock/drill out unless it was at the other end of the muffler.. Answer? Previous owner has opened up the whole end of the baffle out and I was looking straight down the pipe... duh.... So this explains some of the popping I am getting on occasion as there is probably minimal back pressure if any.

Having read that some back pressure is needed how bad is this and/or should I be worried? K&N filter going on in Jan and will take it in for stage one cal but not planning any other performance mod at this time. Thanks in advance!

Just wanted to say thanks for the direction on this. Picked up an Arlen Ness K&N Big Sucker kit to replace the stock air. In work on installing it now (old one out) and not sure where I read about using the dremmel tool with a sheetrock bit to cut the old out I wanted to say thanks! What a life saver... It would have taken me hours with the flat cut bit. No nics and contained most of the mess.

Also, on the performance side. My local dealer put it on the reader and I found that at some point the bike had the stage one flashed already and pipes added either from purchase or after so no cost to me out of pocket there.

Reinstalling old sensors and putting housing on tonight after work tonight so if there was anything else I should be doing other than cleaning the quads, please post.

Thanks again for the help Vicbuilder, ftwflh and others that posted/PMed! Can't wait to get it on the road tomorrow A.M.
