I'm looking into getting nameless cat back exhaust system, I'm not positive what the difference of the single wall and double wall is. What is better? what sounds better? What looks better? anyone with personal pictures too would be a big help

I have been looking at them a bit too. I think it is just the exhaust tip. The double wall is rolled and looks better imo. I doubt any difference at all other than appearance. Maybe stronger if something were to contact the exhaust?

Yup, it just refers the the tips. i have the double walled version on my hatchback, and I think it is worth the extra money. IMO the single wall versions look cheap and flimsy, though I'm sure in reality this is not the case

I like the single walled beveled tips.....

single wall beveled looks good. Double wall looks good. Single wall not-beveled looks cheap rice.

Have you tried contacting Nameless to ask Nameless about the Nameless product?

Also, please fill in your profile. Because for all we know, you're trying to get an exhaust for your 2002 Outback.

in addition to appearance double wall is used to keep exhaust heat off the outer part that is seen so it doesn't discolor

That is a double wall. Single wall means the tip only has one layer of metal like a normal pipe.
Double wall means there are two layers of metal welded at the tip and then polished to give a thick looking exhaust tip.

Double wall is the way to go if you don't mind paying more.
