Just bought a Magnaflow Catback fowm a local distributer. Is there going to be a big difference from my American Thunder Flowmaster??

 

All catbacks are within a few hp of eachother. You're gonna love the sound though.

 

Yeah there will be a difference, your new exhaust will be quieter.

 

My magnaflow cat-back is very loud... and thats without the headers installed yet

 

Same here....it's at a decent loudness level down low..and up top it gets really really loud..I love it!

 

magnaflow is by far my favorite

 

My sisters Magnaflow sounds awsome on her z. Punchin it is the best part.

 

The Magnaflow is good because when you hammer it, it gets loud enough to wake the dead. But when you're idling or just cruising around, it doesn't have any of that annoying drone or rasp that most free-flowing exhaust systems have. Pretty much the best of both worlds.

 

I have one that I haven't installed yet. I am scared about it being too quiet without headers which I will not have until next fall, if I haven't sold my car for an LS1 by then.

 

It should sound good, but by no means go selling your LT1.

 

yeah ls1s are LAME!!!

 

I have one now too and it's really quiet with LT headers. I also replaced my muffler that had a hole in it though.
