Replying to: Mr_Shiftright (May 10, 2005 8:25 am) Anyway, after I got back, I noticed right away that the mileage was poor and that the car lacked a lot of oomph (for lack of a better word). I had to get the car inspected for registration purposes, anyway, and so I brought it in. I was told then that my muffler had a leak (they showed me the hole, so this is legit). Because they had to order the part, I took my car out of the shop for a few days to pick up my mother at Dulles. On the way, after stopping for lunch, the car repeatedly stalled on me for a while, and even when it kept going, I still had the problems noted earlier. I brought in, and they said my catalytic converter is pretty much fried. I don't doubt this, as the symptoms I described earlier match what one would expect with a bad catalytic converter (at least based on the internet research that I've done in the last couple days). Anyway, to replace both the muffler, pipe, and cat, I've got an estimate of about $590. For a car that only books at $2200-2300 anyway, that seems like a pretty hefty repair bill (at least on my budget). In any case, I'd be willing to pay it if I knew that all would be kosher with the car again and that it wouldn't be right back in the shop a couple months from now. That said, everything I've read suggests that catalytic converters go bad because of other problems: timing, bad fuel mixtures, etc. I guess the good thing is that these problems sound easily remedied and hopefully wouldn't cost all that much. However, is it possible to figure out what the problem is before I authorize the replacement of the exhaust system? Is it possible that the cat died because of old age, much like the muffler seems to have rusted out? What do I need to think about before authorizing this repair? Thanks in advance to any with answers! |

I have a 2000 MAZDA MPV with 72k miles on it. This vehicle has the exhaust manifold integrated with the converter, the 2 can't be bought separately. It actually has 2 manifold/converter pipes, one onthe left one on the right. The one on the right has developed a hole (NOT a crack) in the pipe, in a wend near where the gas leaves the engine. 2 questions: 1) Would this part be eligible for the 8 yr/80k emissions warranty? The converter box looks fine but you obviously can't replace the manifold pipe without pulling the converter 2) How do I approach the dealer on this? |

I am trying to gather information about exhaust systems available for my car, a 1996 Ford Mustang GT. I am wanting to replace the exhaust system from the headers on back. I have spoken with a few people but I am unable to understand the whole package. I dont have enough background information to make a decision on my own. I guess what I am trying to figure out is not what HP gains I get but performance by upgrading my exhaust system, yet I still want the car to be street legal and able to handle the stress of everyday driving. I don't understand the x-pipe set up. (though i understand some of the physics) what I don't understand is the Off-road description listed on most of the x-pipe descriptions. Do you need a system with an x-pipe configuration? pros and cons

Replying to: corentheius (Jan 18, 2006 1:56 pm) You're not going to get very much HP gains from an exhaust system and header...not sure what you were expecting but if you ended up with 15HP total you'd be lucky. Best way is to look at the ENTIRE intake/exhaust as ONE LONG PIPE....makes no sense to work on one end but neglect the other, and once you've done front end of the pipe (air intake system) and back end of the pipe (what exits the engine), you are still limited by the engine itself (the middle of the pipe). So you do air intake, intake header, throttle body, exhaust header, mufflers. If you want more HP after that, you'll have to consider different camshafts, and/or larger injectors and turbocharging for serious HP gains IMO. |
