Finished putting on my Thunder Torque inserts from DK Customs. Of course they are crazy loud but the performance is pleasing. The sound is pretty deep with a good amount of midrange.
thrill74..... Which TTI did you use? W118, W158, or W258... I want to say the W258's are the right size for the stock slip-ons with baffle and cat removed.
I used the W158's. They gave the right back pressure and a crazy deep tone. It was just so loud though that the reverberation would give me headache after about 50 miles.
