Re: Fuel injectors - Iroc-z 305, 1987

Does "mods" always has do to about performance?

Why else would you gut a cat?

Looks? No Sound? No, sounds like a whale on crack. To be legal? No, it's not. To "solve" a problem? No, you're masking the real one (a poor running engine or one that's worn out) To "gain" performance? "Yes" in the sense of why someone would do it, too bad it's mistaken.

Newsflash: Gutting the cat nets you ZERO performance/gain/benefit.

So why would you do it? :)

Can you give me testresults which show me that the "gut.cat." don't free up the exhaustflow?

Breaking the law? We don't need the cat. on cars older than -88 here and my IROC is accepted at a smog-test in April this year!

Sure, go to any website such as DynoMax's, AP, etc. Type in "gains by gutting cat" into google.com and read about 50 articles that prove you wrong.

Also, you create turbulence in the exhaust by having it gutted which DECREASES your performance and affects torque.

Or go to any shop and have the car dyno'ed.

Newsflash: You net zero. Been proven time and time again.

You've also broken a federal law by removing the cat. Your state law means nothing, nor do your emission requirements for the state. Federal Law supersedes both.

You could remove the cat on a 1975 model year and still be in violation of the law. It's Federal Law.

Again, removing the cat to "enhance" performance is nothing more than ignorance, stupidity and lack of knowledge.

Sure it's accepted, the state's HAPPY to take your money :).

In NYS, you'd do a complete inspection, charge the customer and then say, "You failed. Your converter is hollow. 35 bucks please". And the law would support you 100% of the way.

To add to the "injury" (which you've caused yourself), the inspector has the right to scrape the sticker off BEFORE starting the inspection.

Now you have a car that's failed, you have no sticker (ticket blitz, woohooo!!!) and you're asking to be pulled over. Oh ya, it will cost you to put the cat back on too :).
