cat delete negatives?

[crazycanuck]

after reading all of this I am still going to install the new exhaust with the cat delete pipe pps:

If your bike is still covered under warranty, any modifications to the exhaust system might void it. Oh, yeah, it's also illegal.

Illegal and irresponsible if you care anything about the environment. And, I wonder about that warranty issue...

1) If it's not a catalytic converter, why are people referring to it as a "cat bypass" or "cat delete"?
2) If removal doesn't affect the engine's performance or emissions, why did several people in this thread refer to increased fumes?

I find this from https://www.riderzlaw.com/motorcycle-info/motorcycle-laws/noise-and-emissions/. You can argue if you want but these are other lawyers talking, not just me:
[FONT=&quot]Many riders are familiar with the idea that a “modified exhaust” is illegal. This is an over-statement, and is not entirely accurate. It is illegal to modify a motorcycle in a way that makes it become non-compliant with EPA emissions requirements. This rule has not changed since 1980.[/FONT]
[FONT=&quot]It is not illegal to change a motorcycle’s exhaust system. However, the new exhaust must still be in compliance with EPA standards. Many after-market exhausts are not. Which raises the question of how people get away with putting on after-market exhausts that do not meet regulations? The answer is a lack of enforcement.[/FONT]
[FONT=&quot]In fact, enforcement of the modified exhausts rule is lax, to say the least. That is because it is up to states to enforce it. As a result, many motorcycles on the road today are technically not within compliance. Several states, most notably California, have considered laws that would require smog and emissions checks for motorcycles (just like they already do with automobiles).[/FONT]

Catalytic converter IS IN the primary muffler.

It is NOT illegal to replace the primary muffler. There is no part on the Spyder actually called a catalytic converter.

...other than it sounding better than "muff-bypass" ?

I give up. Not going to argue the point any further. You do what you want with your bike.

Many have used the primary muffler bypass pipes to great effect and have had absolutely no negative effects to the bike or warranty coverage. If its not for you for what ever reason, sound, environmental concern, whatever, then dont do it.

That's another myth too.
