Hey guys my brother bought a 02 Park Avenue, and the exhaust system was crap and he orderd a walker exhaust system for it and we installed it..
But turns out its not fully quiet... Now i kno PA'* usuallly are so quiet u almost dont here anything from the tail pipe.. But it has a kind if Gurgle rumble toit.. And he wants it as quiet as his old old 05 Deville.. Any recommendations?
I gave word tht he could possibly use a muffler off of a caddy.. And to use a caddy resonator as well.. Cuz those caddys are like wisper quiet. But it might not work.. So im coming for some advice..
Is there another brand muffler quieter than the walker quiet flow muffler?
Recommendations??

Get an OEM muffler for the Buick. The walker mufflers are a bit different than stock. My car had a walker catback, and it sounded noticeably different than a fully stock Buick.

So change only the muffler?
Do kno how much or about how much it cost?

And i agree it is very different.. I have one wit dual turbo mufflers so i couldnt compare. But a friend has one stock and u can barely here anything back there

Yeah, just a muffler should be fine as long as there is a resonator. I don't believe an OEM resonator vs the walker would make much of a difference.

I'm not sure on the price of the muffler. I would assume it would be in the $200-250 range. Possibly more.

Ok thanks... & i called the local dealer & they said $384!😳 but of course, i live in expensive Wisconsin where the price of everything seems to always be higher than other places lol..
But i checked gm parts online and i believe they had it for $180 or $280 think ill look into it n get it ordered for em.. Thanks again
