if this is the only powertrain mod you are planning because "i want it just a little louder"..why not just get different mufflers instead of kicking your powertrain warranty to the curb along with maybe needing to have it tuned with an aftermarket tuner and the expense and hassles of doing so.. it might run cooler as well but...

Be advised that the change in exhaust note is minimal according to some who’ve tried it. Tuner is unnecessary because there’s very little flow gained by taking it out. This isn’t the same cat that the TCs had.

Me, I’d leave it alone and not risk warranty issues.

You dont "need" tuner, but... If for some reason I made those changes I would not contemplate doing it without running a different tuner / map.

Definitely less heat without the cat and a little more sound, especially on decel. Sounds great and runs great but i have fuelmoto headpipe and PV

no i'm not chasing a shovelhead sound,shovelheads have their own sound that an m8 can't match nor do I want it to.i'm after a little louder sound.maybe you could try to post something useful to this thread .thanks to everyone else that had positive comments.i'll probably keep it the way it is until warranty is out then do some more mods.

I gutted mine ,and installed two brothers mufflers , similar to Reinhardts. No need to tune. Runs better sounds great .

Slight change in exhaust note......passenger very happy as the little bit of heat that was there in 95 degree days.....gone in the cat area. No tuner on one I did ,but it had no other mods. Oh and it's had warranty work 4 times now and never noticed.
