cadillac_caddy_sts Posted October 17, 2004 Report Share Posted October 17, 2004 Okay I am only 16 just starting to learn about Cadillac and I always see things about a catalyic converter and how if you remove it, it will increase your horsepower and make the exaust rumble more is this true and how do you do this? Where is it located? Another thing is what is a WOT? If any one can help me that would be great. Also my power antena will only go down three quarters of the why any suggestions there?

Ranger Posted October 17, 2004 Report Share Posted October 17, 2004 The "cat" is under your car in the exhaust system. It looks like a muffler and is the forward most one under the front seats. It is there to help control emissions. It is technically illegal to remove it. If you have emissions testing where you live, you won't pass without it. If you were to do it you would have to cut it out and weld in a straight pipe in it's place. I don't know about HP. It will lessen back pressure but I don't know how much HP removing it will add. I'll leave that to someone else. WOT = Wide Open Throttle Link to comment Share on other sites More sharing options...

jschunke Posted October 18, 2004 Report Share Posted October 18, 2004 Some folks "gut out" their catalytic converter and leave the body in place to disguise their evil doings. But the car then sounds so awfull and noisy its amazing they aren't pulled over and thrown in jail. Link to comment Share on other sites More sharing options...
bigfoo Posted October 18, 2004 Report Share Posted October 18, 2004 help save the environment! if you are worried go buy a high flow converter and put that on instead.. i'd run a converter on my lawnmower if they made them. :) Link to comment Share on other sites More sharing options...
joeb Posted October 18, 2004 Report Share Posted October 18, 2004 My STS sounds ok. my son just replaced his entire exhaust on his grand prix GT. he put on a high flow cat and dual borla muffs. he took out the resonator so it is quite a bit louder. i took it out for a test drive and it definitely resonates at different rpm's and throttle settings. its a pretty good looking system with the new SST tips. i am debating about changing out my system but time will tell.

an01sts Posted October 19, 2004 Report Share Posted October 19, 2004 They used to call it deballing when removing a cat. Take if from a 46 year old geezer: As a population, none of us gave a darn. Likewise with our predessors; as a result, we have left you a $hit hole for a planet. At 16, it's up to you guys to try to keep making the $hit hole worse; otherwise, there won't be anything left. Cats disipate nitrates of oxide (NOX). That is one of the worst elements in air pollution. Car population has exploded in exponential numbers since pre-cat days. Even so, air pollution has been reduced--it might be 40 to 60% since the good ol days. As pointed out before, removal of the cat doesn't do much for performance. The 70's & 80's cars may have gained some performace, but the new cars don't gain that much. Another problem with removing the cat, putting a by-pass pipe, then stuffin' in a cat for an emission inspection, is that federal law requires a written document, stating that the cat failed and the reasons why it failed. Many states that do emissions do a visual inspection of the cat. If it shows signs of replacment, the emission tester needs to see the documentation for replacment. (Unless the shop is sfb, it will not participate in shady deals because the fine is staggering, enough to put them out of business.) About the good ol days. (I have a 69 Firebird that I chereish.) Those cars were crap, and new cars blow them away. Timelines don't lie. If those cars cranked mid 13's, they were bad a$$ cars. Now a days, times like that aint crap. As to how old cars drive? My daughter, now 23 and the owner of a 2000 R/A T/A, drove my Firebird shortly after turning 16. Yeah, she enjoyed the throttle--wich aint anything like her T/A--but she was so dissapointed and said, "I thought this was a nice car to drive."
