dude, every post ive ever read on here about the at3030 comments on how loud it is. trust me, the thing is LOUD. i can set off car alarms with it. i can only imagine how loud this thing would be with long tubes. whoever told you the at3030 isnt that loud is a moron.

 

i have to 4.7 i dont know about your laws but in Minnesota its pretty much anything goes and i know one other person with the same exhaust as mine and there both loud all it is is 2' cat back local muffler shop did mine with 45s its the loudest in the town (lots of pipes in the town)

 

check out the at3030 on youtube. You will crap your pants. I heard one that had a resonator on it and it about blew my speakers. It's LOUD.

 

if you would like i have a video of my exhaust that i just uploaded its dark and sounds ok but its definitely better in life http://www.youtube.com/watch?v=YSFsZKgfgw0

 

I would definitely get the AT3030. Forget the FM. I am curious about the difference between the AT3030 and the AT303XL. Is the AT3030 louder? I have listened to both on youtube but some peole have resonators and some dont, and some other mods so its hard to tell. Which one are you guys with the Aero Turbine's running?

 

the difference between the at3030 and the at3030xl is that the XL version is resonated. it has a resonator inside the muffler, therefore it is not quite as loud as a normal at3030

 

IM DEF GONNA ORDER THE AT3030 next question is should i leave my stock resonator on or should i replace that pipe with one without a resonator? and what size at3030 do i want,a 2.5 in/out??

 

hey ryan what do u have for a setup? single exhaust? stock y? is it a 2.5 in/out at3030? and do u have the stock resonator on or off? pics of the setup?

 

i thought 3030 meant it was 3" in 3" out. and 2525 2.5" etc?

and leave the resonator in place drive for a while. if you dont like it remove it. its easy to take stuff off, not so easy to get it back on

 

Ur right mexico,4.7's use the at2525 so thats what ill get.now i wanna find a premade y pipe which is 2.25 in 2.5 out
