Muffler delete - best thing ever!

So we all know there is no solution in a box for the 228. I decided to pull the trigger on a muffler delete and throw on my exotics tuning diffuser. I will take a vid of how it sounds soon, but guys, I can tell you. its awesome. Not loud at all. you barely notice it at idle. It sounds deep and refined on revs. Reminds me of what my evo 8 sounds like when it had the stock catback, but was de-catted.

the sounds u hear at 10-14s in the vid. every time i come off throttle at low rpm... rolling in traffic say... its nice. once above 2k rpm the burbles go away mostly. Cruising at 55 u dont hear the exhaust at all... i really like it.

i didnt notice any at cruise. the setup is surprisingly quiet

.... also, whats different to the other muffler delete vids i saw posted on here, my car is the 6MT. so that may play into the experience im having with the mod.

stock intake running the afe filter.

It surprised me how much u heard the bov in the vid, cuz i dont hear it much at all from inside the car. I have an injen intake coming courtesy thescout13 on the forum, so i should ahve that in by this weekend or next.

As it is, right now my car is up on the jack at home. i need to complete the install of the ER cooler and the H&R springs.

Glad to hear more and more people are doing muffler deletes. I love mine and it sounds freakin awesome! I'm running catless downpipe and no resonator so mine is a bit on the louder side. It even spits flames when on map 7 with e85 fuel
