Replacment Exhaust

[shortstar]

hey my bro needs a new muffler and it cost way to much to buy a new stock one since GM parts direct doesnt sell them.

I was thinking the flowmaster 40 would be a good replcment but I need to lnow which one to get... I just want the single output. Which offset do I need? does it hook up to the eco fine? do I need to buy new tips with it?
Thanks

It won't be an exact fit, you'll probably need new pipes for that, but by the sound of it, you'll need them anyway.

Just stay below 2.5" pipe

I had my 40 series flowmaster just attached and mounted to my existing pipe, i have the offset in-center out 40 series, 2.5inch ID.
I had to add a tip, with that muffler the tip has to be short, i used a magnaflow one.
