MAC rustback system
 

Hey,

I have the 2.5" MAC catback for LX. It started rusting quickly from week one and requires constant attention. The main problems that I can see are the exit edges of the chromed tip and the inside wall of the pipe as far as I can see into it. I've sent a set back before for the same reason. It got so bad that the baffles in the muffler rusted out and started making ratttling sounds. The car does occasionally belch out water at startup (maybe 1/2 gallons?) My engine is completely stock and runs great. Its not coolant. I heard from many people that a healthy engine does this. I've also seen brand new cars doing it. Shouldn't the exhaust system be able to take this normal amount of condensation? Does anyone else have this same experience? A buddy's Flowmaster catback also rusted a lot. I want to complete the rest of my exhaust with headers and off road pipe but don't want to waste cash on garbage. What are your experiences? Anything more rust resistant out there that doesn't cost an arm & leg that doesn't require welding?

hehe I have been there done that Thats WHy I get SS stuff only now i know it is not cheap But it is worth it to me!!!

I've got a full MAC exhaust, it's been in for about 1 year now, and it still looks new. Did you get it w/ the coating? THe only thing I have MAC that I don't like are the lt headers (they rubbed on the steering shaft and needed to be "coerced" in order not to rub!

Yeah, HTS. The coating is the only thing rust free. Maybe they should put it on the inside too.

My MAC catback's tailpipes are a rusty mess, the chrome was flaking from day one and now they look horrible, I don't have any rust on the inside of the system though.

Just buy some stainless steel tips?

stainless tips, with borla mufflers:D yea but they cost an arm and leg, does anyone like the borla sound? im thinkin of getting some.

I had the same problems. My tips rusted the 1st week they were on the car and MAC gave me the run-around when I tried to get them replaced. I'll never buy MAC products again.

Borla's sound awesome. If you have ever heard a Saleen, and you like the sound, well, Borlas are what they have on them. They are free flowing, and have an awesome look and finish that won't rust or flake. If I wasn't so broke right now, I would get them instead of the flowmasters im going to get. Down the road, ill be replacing the mufflers with Borla's.:D Hope that helps.
