I want to change the CAT and Mufler on my '95 SSE. I know that the exhaust is stainless steel, which presents a problem when finding a replacement. What sort of problem can I expect by replacing the CAT and Muffler with Aluminized parts? Are they going to rust fast? How long? I saw a lot cars are using the Flowmaster80 Series (about $80), but it'* aluminized. I found a stainless steel muffler, Dynomax UltraFlow SS, for about $150. Other than the difference between stainless steel and aluminum, which one is better? I'd like a mellow sound but more free flowing.

Also, is there a stainless steel hi flow CAT too?

Just go with a name brand like Magnaflow, Flowmaster, etc.. You will be fine.

I think that Dynomax UltraFlow SS, is a good choice, as IM thinking of getting one also however I want to hear one in person

I like the sound of the flowmaster 80 series.

Be ready for some raspy exhaust with a H/F Cat.. sometimes if the 3800 has too much opened up it can sound a tad raspy. I've got a flow master 80series and it sounds scrumptrilecent! ..just my 2 cents ..yes, i said scrumptrilecent. I believe Will Ferrel invented the word.. but i can use it too, haha.

Agreed......I have the 80 on my SSEi also....and it has such a nice idle tone to it....Almost comes close to sounding like a V8.......Has kinda a tin can sounding tone like the old muscle cars...........Just beautiful.....

I agree, Flowmaster 80 is awesome, especially at idle. It could put a baby to sleep

Does it sound louder in the cold early mornings like a CAI does?

Only if the idle is higher.
