Well Im looking for a stock exhaust and 2nd cat for my 05 Mazda3 2.3 hatch. If anyone has one for sale let me know. Also, I have a Mazdaspeed exhaust with a custom straight pipe thats been on my car for a few years. I think it might have a leak somewhere in it, but if anyone wants it, we can do a trade straight up. The straight pipe has a bung welded in it for an 02 sensor, but I used it for a wideband when I was boosted. I have had to weld the exhaust a few times over the years. The only thing is if someone wants to trade, I would need to have it put on my car before I could send it, if it had to be shipped. I have to drive my car daily so I always need. If I cant find anybody to trade I will need to buy a stock exhaust..
