My flowmaster exhaust is rusted out but I don't know which i have since it's from the previous owner. I know it's 3" and the muffler has a single outlet that appears to be 3". I heard these flow better so maybe I'll get this same one. I'm not sure of the part number though, anybody here know which one it is? Oh yea I need a new y-pipe for after the cats too, that's actually what rusted out but I'm going to replace the whole thing.

From looking at summit racing I think i have the american thunder except my muffler is only 1 outlet on the left, not dual exits..

 

Just ordered #17150 from summit, the Force II 3" for dual cat cars. I hope it comes with the "intermediate pipe" for my cats. That's the only reason I got it and not the SLP cat back.

 

First of all I'd like to see how stainless steel exhaust can rust.... anyway here is a link to American Thunder single outlet exh. GL http://www.thirdgenresource.com/inc/...l?v=1&pid=2906

 

The American Thunder setup is dual exhaust out the rear, Force 2 is a single out. I also think that the flows are not stainless steel, but aluminized steel. I think if they were stainless say like a borla I would hope they would give a better warranty than 1 year.

 

No flowmaster is stainless steel and the link I sent was a link to a single out American Thunder cat back system... the picture is not the actual product its just a picture of one of the American Thunder exhausts. GL

 

hey ledzep, here's a quote from flowmastermufflers.com
"Both mufflers and tubing are fabricated from aluminized steel forcorrosion resistance." and i thought the mufflers were stainless steel, but i guess not

 

They were stainless steel last time I looked says it on my cat back...

 

Nope, Flowmaster is not stainless. The TIPS are.
