i want the slp 2otl catback but dont wanna pay $400 for it, and dont really wanna buy it used b/c i wont know the condition of it until i have it, so i was considering going with one of the "aluminized" catbacks and wanna know how long theyre good for.

 

Mines been on car for about 6 years, and its just now starting to get rust spots on it. Gets driven in rain, snow, salt etc. Go for it.

 

I went through two, MAC crap-back's in less than two years before buying the SLP 2OTL. The SLP is definitely worth the money.

 

Never had a problem with aluminized exhaust. Only if you do not drive it much.

 

The 2otLeft is a sweet exhaust system. I've been running it for 5 years, and I get compliments on the sound of my car all the time... then again I do have a 383, headers and no cats.

 

ive ran hooker for well over a year and still looks perfect as well as the tips as long as you keep them polished

 

I got Flowmaster Catbacks and its been on there for like 5 years and still going strong.

 

I am thinking of running the hooker, are their any sound clips anywhere? Thanks!

 

I have the Flowmaster cat back on my '95 and it was put on by the original owner months after he bought the car new. It still looks great. The car has 106000 miles on it.

The biggest single factor in exhaust longevity (after clorides in the converter washcoat, but that's a different story) is how much condensation the metal is exposed to. If your driving is mostly long trips where the engine and exhaust is fully heated before shutdown, there is no condensate on the inside, and your system will last much longer. If you take a lot of short trips where the system isn't hot and burning off the condensate, then that condensate will eventually perforate the system. An aluminized coating will only delay the eventual corrosion. I have seen aluminized systems look good after 150,000 miles (in Detroit no less), and I've seen others perforate within a year, both having the same or similar material makeup. Longevity is almost entirely dependent on long term driving patterns. Road salt has an effect, but not as much as you might think, and certainly not as much as short trips.

Stainless steel changes the equation considerably. In all likelihood, a stainless system will last as long as (or longer than) the car, unless it's the lowest grade.

 

I agree with the above.. I have the aluminized Random Tech (been on about 3 years or so) and it's got some rust here and there on the outside, nothing too bad. But the inside is a completely different story. Totally rusted to hell.. In fact, I just got done yanking the whole thing out this afternoon. It's going in the trash in favor of a Magnaflow.

 

I had a flowmaster and that rotten to hell.

 

ive had my hooker on the car for a little over a year and half now and it is doing good. no rust and it is driven in snow and rain all year round. although, i had a flowmaster on my old 86 TA and it started rusting after about 6 months. but that was a very heavy winter with a lot of snow on the road. hope this helps
