i reallize that a smaller diameter exhaust will give me less horsepower on my truck which i dont care about?

Question

but will i get the high pitched crack that i want by running smaller pipe right now i have duals with no muffler and 2.5 pipe will 2.25 pipe do the trick?

Answer 1

Jeff, going from 2.5" pipe to 2.25" pipe will have a very big difference in the way it sounds, especially since your not running mufflers. On my 99 Silverado with the 4.8 V8 (I have done this on other vehicles, but this one was my latest Chevy, so I'll use it for example) I ran true duals with 2.5", 2.25" and 2" pipe on it, all sizes were ran without converters or mufflers, and there is a VERY big difference between the way they sounded. I started off with the 2.5" pipe, and it was just WAY too deep and mellow for my liking, so I went to 2.25" pipe. It had much more crackle and wasn't as deep as the 2.5" so I ran it for a few months and finally decided I didn't like it, either. That last setup I ran on the truck, before I traded it in, was 2" pipe. That had just the exact redneck high-pitched crackle that I was looking for, and combined with a 5 speed manual, it racked like a 9mm everytime I took the rpms up and shifted for another gear. It's really a matter of preference, if you still want somewhat of a deep sound, with some crackle, go with the 2.25" pipe... But if all you want is the perfect redneck sound with LOTS of crackle, go with the 2" inch pipe (as long as your not running a motor bigger than a 350). And on a stock motor, you really wont lose any horsepower between the 3 sizes, but it will change the powerband where your engine starts making torque. The smaller the pipe, the lower the rpms the powerband of your motor will kick in. Hope I helped, good luck man!

Answer 2

NO! You will not be able to tell any difference. The crack comes from a leak in the header gaskets, or dough nut rings where the pipe attaches to the header manifold. A 1/4" difference in the diameter of the pipe will not make an audible difference enough that you will be able to tell. I have messed with these things for years, and I know you will not be able to tell that much difference. If you are thinking about trying to duplicate the sound of a tuner car then you are out of luck. If you go down to maybe a 2'' pipe then you might get there, but maybe we need to understand just what it is you are trying to do. Common sense tells you that a shorter pipe will have a higher pitch than a long pipe. Have you ever saw a wind chime made from pipes. The shorter the pipe, the higher the pitch the sound is. An pipe organ uses the length of pipe to make its sounds, and the tone is controlled by the length more than it is the size.
I hope this tells you what you want to know. Good luck!!!

Answer 3

I would say yes if you use the right muffler. My Maverick had a high pitched crack, it had 2 1/2" exhaust with bullet turbo muffler. While my truck has 18" glass packs with 2 1/2" exhaust and is just loud. You may find you have more power with the smaller exhaust, a 2 1/4" dual system with a good muffler typically gives more torque and hp with a small block.

Answer 4

the shorter the pipe the higher the pitch -smaller diameter will just have a muffling effect - for shorter ( and louder ) try a side exit ( behind the door )
