Hi,...
I just had the resonators cut off and straight piped today at the local muffler shop (Hoegler's in Richmond, BC) and wanted to share my impressions for anyone else looking to try this.
The sound is deeper and has a nice V8 rumble to it now. There is a slight increase in drone in higher gears around 1700-1900rpm.
...
Back to the FX: I'd recommend this to anyone looking for a bit more bite from their FX50 without spending a bunch of cash on a complete system. Price31, no offense (and much appreciated that you led me onto this mod

) but the sound from your video almost put me off doing this as it seemed really loud. I bit the bullet and took the chance anyways and I can say that around town driving @ 6-7/10ths is actually really nice. Not too loud, not raspy, and not ricey!
I hope this closes the loop for anyone on the fence about this mod... the video is pretty loud and is representative of when you really hammer it. But brisk driving around the city, it was well worth the $150 spent!
PS Hoegler's did a great job and the welds look nice and clean.
Cheers!
