Cat delete, is it worth the money

[Albec]

I'm curious. In states that require annual inspections, do Spyders have to be inspected? If so, do they check for the presence of a catalytic converter?

I am surprised vendors and people talk so openly about cat deletes for Spyders in the US where there are laws regulating such equipment.

It's not really a cat so much as a baffle or someone else probably knows the terminology, but it's not a catalytic convertor.

BRP CAM AM service manual says Cat.

It absolutely is a catalytic converter. Look on your emissions sticker.
Look for TWC. TWC stands for Three-Way Catalytic converter.
Here's what my emissions sticker looks like.


BRP calls it the primary silencer. Which it does well, but still flows plenty of exhaust gases.

In addition to the catalytic converter, the stock secondary muffler is also part of the EPA's noise limit, but not the emissions.

Frankly I just keep the whole exhaust system stock. A cat delete and replacement muffler might cause a small boost in power, but it will move it up the rev range where to my mind it is less useful than power and torque lower down. The Spyder is setup to run with the stock exhaust and the only true way to increase power is modification to the engine internals including valve sizes and cam timing and possible compression lowering and turbo or super charging. Freer inlet and exhaust flow is not going to do very much.

I think the Spyder makes a decent exhaust sound when revving it, even when I have my hearing aids out. I like to ride under the radar, so the less noise I make the less the rozzers will notice me.

I know removing the cat and using a different slip on saves weight, but I could do that by going on a diet. Lol.

I’m in the keep it stock and use the probable $1,000 I’ll save on gas to go places camp. If the exhaust is louder I’ll just have to turn up the volume on my comms system to hear my wife.

This of course is my opinion and your mileage may vary.
