i was just wondering if anyone has any quick, cheap tips to make an exhaust a little louder...i alredy have an exhaust system on my truck but want to make it just a tad louder

i just had a few idea's....would drilling holes in the pipes make it any louder
or anither idea was i have 4 cats on mine, how much of a change would it make if i just toke off one of the cats and was left with only 3.

 

dont be ghetto and drill holes

if you dont have emmissions in your state, lose the cats ... still not loud enough then take out the resonator.

 

Lose the cats if you want to but you will lose power. Or be cool guy and unbolt the pipe at the flange under the passenger seat. You wont hear your music or anything. LOL.

 

Bigger and longer tips.

 

pull the cats. if you lose power you won't notice it unless you are on a dyno. if you still have mufflers then you will still have back pressure. which i still don't believe that back pressure is good.

 

Back pressure helps pull the exhaust gasses from the cylinders. So the exhaust pulses act like a vacuum as they exit the exhaust system. Turbo cars can run a straight pipe because the turbo itself acts as a vacuum.

 

I have seen cars on dynos swap stock for straight pipe and have come out with 10 - 15 hp..

 

Without backpressure you wouldn't have near as much torque, hence why flowmaster mufflers LOSE torque from the stock exhaust (yeah yeah you all can argue but it's true). You need some backpressure.

 

Yeah peak power. When you are that high at of an RPM back pressure doesn't matter as much. Low RPM is where it matters.

 

Do a cat back and be done with it.

 

just throw in a Y-PIPE and call it a day that way you can swap back and forth.

 

Buy a muffler and have it custom installed. That's what I'm doing. Get yourself a Magnaflow single in/dual out, and take it to an exhaust shop. Have them bend all the tubing. Shouldn't cost mroe than 2-300 bucks and it won't sound ricey.

 

Keep the cats and just remove the muffler. It won't be as loug as you might think.

what size tips and what kind are u putting with ur magnaflow

 

The magnaflow I have is a kit. The pipes are 2.5" and the tips are 2.75"

When I changed the tail pipes I just cut down those same tips.

Cheaper to buy the muffler and have the pipe custom made..

 

I have a 2.5 SI/ 2.2.5 DO muffler, and the tips are 2.5 in and 3 inch diameter. They are 18 inch long stainless magnaflow tips, 15 degree slant, rolled edge. They're nice but costly.

I was hoping to get it on sooner rather than later but I don't think I'll have the spare money for a while

 

I have a Flowmaster original 40 series, I'll let you have for cheep. Single in, duel out. It was much to loud for me. (But then I'm 70) All the young'uns around here loved it. A few even told me they thought I had a V8 in it. LOL. I had it on my 2002 3.0L for about a year. (roughly 15K miles) Let me know if you're interested. I must warn you though. It did cause the engine to lose a ton of torque on the low end.

 

Removing cats should be avoided.. They are on the truck for a reason.. Just run a straight pipe in place of the muffler or something, or run a 1 chambered muffler like a 10 series flowmaster.

 

Yeah but the kits are made with mandrel bends which make more power than crush bends.

 

Mufflers are on the truck for a reason too. Catalytic converters are on the truck to covert harmful gasses into less harmful gasses, not to increase back pressure.

 

Put an electric cut out on it before the cats.
Headers may also make it louder.

There is no cheap way. Short of taking off the exhaust system and fabbing up some dumps after the manifolds.
