Usually, extreme short life of a flex pipe means one or more of your engine mounts is broken. Get a helper, pop the hood with clearance in front and in back of the van, STAND TO THE SIDE!!!, have the helper press hard on the brake with the left foot and rev the engine with the right foot in both forward and reverse. Your engine should shift slightly. Any more than slightly or any kind of knock/shift means you've got a broken mount. That said, I often only get 2 years out of a welded-in flex pipe section. The weld tends to create a nexus-point for rust to start and it immediately jumps to eating a hole in the flex section. Northeastern Exhaust/UPSW Auto Parts (same company, I think) sells a complete stainless cat-back exhaust system plus all the pieces separately. They sell on eBay and Amazon, plus through their website and I've had the complete system in my amazon cart for months now, thinking of pulling the trigger. It gets good reviews and it WOULD be nice to not have to worry about the exhaust for 5+ years instead of having to pay a couple hundred bucks every other year at State inspection time plus have a loud van for all the in-between times. The only thing that would give me pause for just the one section is that, if your exhaust is like mine, it has had so many cut/patch jobs done that all the flanges have been replaced by clamped and/or welded sections, so I couldn't just bolt the new section in. However, the cat-back system is under $600.Had the flex part of front pipe spliced in and it only lasted a year. Should I have replaced the whole pipe or is that the life of aftermarket parts.
