how loud?

[DmaxPower]

i have a 1994 c/k 1500 ext cab 350....and i just wanted some opinions on what i should get for exhaust? i think ive made up my mind though: 2.5 inch pipes y-ing out to go diagonal thru the back ending with 4 inch tips. How loud do you think that will be? i have the cat on and the pipe that goes thru the cat and from the cat is give or take 3 inches. the exhaust i have on now is the 3 inch pipe from where i took off the muffler, and that ends right b4 the truck bed starts. so give me your opinion!

I have a 88 chevy c1500. I have true duals from the exhaust manifolds back no muffler, no cat. It is very loud. 3" pipes, 4" x 24" tips. Straight out of the back under the bumper, sounds great. If you want louder bring them at a ninety behind the rear wheels....WARNING, the rocks and stuff thrown from your tires will damage the chrome.

turndowns will make it louder (at 90 before the rear axle, you exhaust shop can put em on there are resctrictions on how close the turndown can be to the cab)

i know these things...but no one has really answered my question yet. i just want to know how loud they will be if i have em like i said in my first post. thanks

Loud, we really can't describe the sound over the net, but if you want it to crackle, get rid of that damn convertor!

[DmaxPower]

i get ya...it would be more loudness then a low rumble right?

[broughy84]

It's will be a pretty good rumble, Are you looking to bring them out the sides or 45 them or bring them straight out the back. If you want to hear them more, bring them out at the sides or 45 them and bring them out at the corners of the bumper.

[quicksilver04]

you get a good rumble, and as he said do away with the converter (or do as i did and gut the thing, it is easy) do so will give you a louder sound as well as more rumble

[DmaxPower]

well i had told them that i wanted 2.5 inch pipes starting from where i disconnected the muff then y-ing them out at a 45 ending w/ 4 inch stainless tips, and i plan on havin them do that monday. i think i will have them take the converter off along with the process of putting teh pipes on. my friend has true duals - 2.5's from the from the headers w/ 2 cats on them y-ing out to a 45 with 4 inch tips. i think that sounds awesome

[broughy84]

They, if you mean a muffler shop, can not legally take the convertor off. You will have to do it. I know this, my uncle owns the local muffler shop.

yea i guess that makes sense. so how loud will it be if i take the cat off then havin 2.5 inch pipes and 4 inch tips? if its enough to give you a migrane goin about 50 mph then i dont think ill do it. but i dont want low rumble either that i cant even hear at all. damn idk what to do

[broughy84]

Listen, I have a friend with a similar setup. He has a y pipe after the cat, he had the exhaust come out the rear and you can hear it going down the hyway with the radio off, but if you turn it on you can't hear the exhaust. His are loud, Especially if he gets between tall buildings downtown. It will sound louder in the cab if you bring it out at a 45 angle under the bumper, but it really wont be anylouder you will just beable to hear it more.

ok...i have made up my mind then. im goin to take the cat off then have 2.5 inch pipes y out at a 45 w/ 4 inch tips. thanks guys

er wait, i just went outside to look everything over and i measured the pipe of where i disconnected the muff. i had thought it was 3 inches but it is actually a little more than 2.5 so about 2 5/8 is the actual length. but i think im just going to disconnect that pipe right after the cat and it will still be 2 5/8. i really dont feel like taking the cat off and im not sure exhaust pros (muffler shop) will be able to deal with that very good and its to much hassle anyway.

Man, if I were you I'd leave the converter. The truck will have a "slapping" sound when you get on it any little bit without a converter. Straight outs are LOUD and very illegal. You'd def. get pulled if you drove in town alot. Most muffler shops where I'm from will actually ask if you want the converter took off, atleast the one that did my exhaust did. But I would really not suggest you doing that, unless you just want your truck very loud!
