I have a question about the exhaust on my truck. It has an aftermarket down pipe but is stock from there on. Shoulder I replace the particle filter, it has almost 290k on it. It doesn't seem to tow like it used to, but no definite problems. I have no EGT gauge so I don't know if its heating up or not. Thanks. Trevor.
