Jeep Exhaust - No Muffler

I got bored so I took the muffler off my Cherokee to see what it would sound like, I think I will keep it off.

Is it bad on the motor if you cut off the muffler and just leave it at the cat?

[offroadingjeep]

@kaelinrothwell It all depends, engines need back pressure to run properly. If you intend to cut off after the cat and leave it alone, then it can over time damage the engine. But temp. it will not damage it. Are you just looking for a more agressive sound or power?

@offroadingjeep im looking more for the sound i dont really need power cause its not a xj im trying to make into a crawler... but i would like to get one thats in better shape than mine to make into a crawler

[offroadingjeep]

@kaelinrothwell Ok, you just need to find a high flow muffler. I havent posted a vid on the new muffler I haved on it. It is a Thrush turbo. Nice agressive sound at idle, powerful when driving but not overwhelming. It all comes down to price vs quality.

@offroadingjeep Engines don't need back pressure, they just have to be tuned to run without it, taking off backpressure leans it out, if a car has OBD-II it'll diagnose and compensate it by riching up the fuel/air mix, if you have a carb all you need is a screwdriver and patience to get it to the right mix, pre OBD-II FI systems need to be dyno tuned to get it right. oh and the cat provides back pressure by the way.

[offroadingjeep]

@RidX4Ricers that is true for high rpm applications, but for everyday use, it will burn out valves. Backpressure assists in low rpm torque, but limits high end power. Yes, the cat does provide back pressure. If you use your car for everyday use, leave the exhaust alone. If you race, get headers.
