American Thunder Catback

The original 40 and super 44 come in in 409 SS but the super 40 does not. The catback is listed as 409 SS is why I ask. I prefer stainless.

Ah, I looked at the kit for sale on AM. It has the super 40's but isn't SS. The mufflers in the link you provided look like super 44's.
 
My American Thunder catback (which was purchased over 5 years ago) has the original 40s. Can't say for sure about the newer ones.


I used to know they came with the 40's but it has been so long since I have been around one I am not sure. I emailed their tech to find out.

for the love of god don't buy flowmaster mufflers
I've had straigh through mufflers for around 8 years. I sold my slp on the board, and I wanted chambered. Bought a set of MAC flopath dumps. I love the sound but can't stand the look of the car without tails on it. I have two choices with a PHB Flows or Dynomax. I like the sound of flows, the kit is stainless, and really it is just a mustang. Nothing ground breaking going on here, so flows it is.

I looked at AM but they didn't have the stainless. Summit has the same kit but in stainless for about $60 more bucks. I can do that.
 
I suppose in kornnut's case he has a viable reason to purchase them due to a phb setup, but for any other reason of purchasing them i despise them. I've just grown to hate them over the years, and it doesn't help that the car i just bought has them installed :shrug:

It is all in what you like. I HATE anything magnaflow. Never heard one I liked. When I put the LTs on the car I wanted an o/r H instead of the X I had and a chambered muffler. Gotta change it up a bit.
