    Rear Cat Removal

    I'm going to D-I-Y delete my rear cats this summer. Being somewhat lazy, where can I get pipes with the correct length, offet, ID, OD to fit in place of the cats to make the job easier?

    Exhaust shops, eBay, FLAPS, Jegs, etc.......

    It's just a straight length of pipe. All you need to know is the diameter and length.

    Looks like a slight offset overall.
    You may wanna extend your piece to eliminate the flanges too.

    The trouble and effort to do this DIY will be offset by throwing $100 cash no receipt to a shop and turning your head for 30 minutes. Keep the cats in case you ever need to reinstall them.

    rear cats

    I recently paid $50 for a shop to do it. They did a great job and I was in and out in 30-40 minutes.

    Sounds great, it's almost perfect. Not too loud, just a nice tone to it. Great exhaust mod if you can get it done for around $50. When you get on it it's just a little more aggressive than stock. I drove it like that for about a month before I found some mufflers on ebay for cheap. VMS Racing is the brand. They were like $35 each shipped. They are basically a magnaflow copy. All stainless inside and out, very happy with the purchase. I recommend them to anyone that is not looking for a chambered muffler sound. It was only slightly louder than the stock muffler but will increase in sound a little over time because it's a straight through muffler with a packing material inside and the material kind of expands over time.

    I have been on the fence about doing this on mine. I have Super 40's and delete tips. It idles with a barely audible low rumble and sounds like hell unleashed at moderate throttle.
