What will cat deletes do for emissions? We have pretty strict testing here in Road Island.

I cannot comment for your car and your state, but in PA we have strict emission testing plus the cat I removed was the secondary cat, not the primary attached to the header.

People in California have commented that they have installed the same modification and have passed their emission testing.

In my situation, I kept my secondary pipes in the event that I do fail and will reinstall them.

The cat delete pipes will not affect emissions because you will still have a cat in each of your exhaust manifolds. As for the muffler, look on craigslist. You can probably find a used one for around $100 locally. Then you can do any of the mods talked about on here. A used muffler that has to be shipped will cost because of its weight. I have a used one in great shape that I would sell for $100, but shipping it would most likely cost the same.

Sounds like the best idea yet. There really isn't much out there. Maybe I should start my own business. I thought it would be easy to get an aftermarket cat back that was lighter than the 40 lb stock unit with better sound. Sheesh.

You can get that, but you will also get a muffler that drones at 3000 RPM. It has been said that the drone goes away with the cat delete pipes. Then of course the cost goes up to closer to $500. So if you don't mind the stock mufflers weight, then a used one that you can mod will end up costing you less.

I have done the Crios mod to my stock muffler. Small sound gain and no drone. My buddy has a stock muffler with the bypass mod. Huge sound gain and no drone.

In the end I guess it comes down to how much you want to spend.

Not sure about the fit, but I have a very low miles stock muffler from a 2001 S model you can have for $300. I'm less than an hour drive from Providence

For completeness, early (97-99) Boxster's only have a single cat that is installed down stream of the exhaust header and before the muffler (not integrated with the exhaust header).

Deleting the single cat on an early Boxster will result in emissions test failures every time.

Get the TopSpeed or eBay muffler. They are durable, sound great, and are an excellent deal compared to much higher priced alternatives.

+1 ^^^^ Contact Che at top speed, he usually gives a 986 Forum discount. Get the cat delete pipes also and the EZ seal clamps and you will have a great exhaust with little to no drone. I honestly don't have any with mine.

+1 concerning Che. I've done business with him in the past, and he is great to work with.

No issues in California as long as they don't do a visual inspection.

Hey BRAN.. I am not sure you're correct. I believe that the 00004420020 is for 2003 and 2004 Boxsters. It doesn't have those large wrap around pipes due to the bumpers on those year cars. The 00004420012 one is for 2002 and earlier cars. I bought (stole?) a PSE off of eBay for $125 shipped. It was poorly listed.

Not to muddy the waters, but how long do the cats last on these cars? Reason I ask, if my cats are going to give up the ghost soon, I'm probably better off waiting until the bank account recovers and go with the full system, like Fabspeed (over 2 large...ouch). Coming up on 70k miles soon.

How I wish I could find a full OEM sport exhaust on ebay for $125.
