loud exhaust..

I always appreciate the intelligent answers to my often dumb questions and hey I have another dumb one for you guys, er probably dumb.

I had a single cherry bomb glasspack on my truck for a while after chopping the stock exhaust to the cat off. Its a bone stock 302 in my 94. It was still pretty quiet but alteast I could hear the motor. With the stock exhaust the truck was as quiet as a mouse. Then I developed a giant exhaust leak up front (manifold got disconnected from the down pipe to the cat.) You could hear it coming.

Fixed that then I straight piped the truck. Im using 2 1/2" exhaust pipe. The thing sounds about the same as it did with the cherry bomb on it. The truck is still so quiet. I know im going to sound like a dumb kid saying this (cause I am one) but I want a louder truck. I love a loud V8. Any suggestions to make my beast scream?

Cut the cats off! Then it will be loud.

Or you can run open LT headers like I did for about 6 months on my 86

My truck was the same way. I have the 351 and was dissapointed as to how quite it was with a glass pack on it. I removed the cat and installed 3" pipe back to the single in dual out flowmaster 40 series. I then ran 2 1/2" duals at 45 degree angle with 3 1/2" bells. Much louder and sounds awesome. Nice deep rumble.

I once heard a 302 with true duals. There was a cat on each side. No mufflers. The previous owner cut the mufflers off. It was nearly FACTORY quiet.

Cut the cats off. Don't touch the o2 sensor. Leave it alone or you'll be in trouble. Then your truck will be obnoxiously loud!

I'm running a high flow cat, nothing eles. Can hear me coming about a mile away in residential neighborhood. I kinda feel bad when I go to work at four in the morning waking up the neighbors... Sometimes, not often.

run headers with straight pipe and "y" cutouts and it will be loud. or the shorter you leave the pipe the louder it will be also.

Take the cats off and drive a pipe through them. Looks stock, but frees up the exhaust.

the closer you have the muffler to the engine the bigger the difference also....i think its farther back louder, closer quieter......

that may be the other way around though....

You're nuts man. I ran open headers one time, from my house to the muffler shop and I was sweating bullets the whole time. That thing was friggin LOUD.

what i did with mine is i first straight piped it and still didnt like how quiet it was, and then i decided to take the cat off but i was to lazy to go to the store and buy a cheap piece of pipe so i just broke the honeycomb structure in the cat up, started it up and blew the crap out a few times, took about a half hour but i didnt have to buy another pipe, and it made it a little bit louder, i just ran my tail pipe out to the front of my passenger side rear tire, it doesnt sound horribly loud but i definetly sounds nice, i still have the pre-cat on because i didnt want to mess with the emissions control, but im sure performance headers im planning on getting will up my volume.
