ways to make your jeep sound louder

Im looking for any cheap ways to make my jeep any louder. I dont want the loud jap car noise but a low throaty noise. I already have a flow master muffler and a cold air intake by spectre. Are there any other ways to change the sound and not spend a ton of money?

Take a sawzall, cut the pipe in front of the catalytic converter, enjoy your pointlessly loud exhaust. Louder does not equal better, and 4.0s don't sound very nice anyway.

Try a different Flowmaster. There's 30 series , 40 series , super 44, 50, 60, 70 search YouTube till you find the sound you want then go buy that muffler.

"low throaty"

There's only one way to do that with the 4.0. Cut the catback off, rev to 3500. You get this nice throaty growl. At 130dB. The neighbors will hate you. But it's so worth it. For about 5 minutes. After that, you're tired of it and you haven't even gotten it under load yet. That's when it really gets loud.

Unfortunately, the 4.0 is not a nice-sounding engine and doesn't do "throaty" well.

Also, cut the "jap car" comparison nonsense. That's just Hondas and the way you say it makes you sound like some backward idiot. Your statement also suggests your knowledge of why riced Hondas sound like that is lacking. Suffice it to say the size of the 4.0 precludes that noise, whereas the smaller engine of say a 2.0l Prelude makes that sort of sound with a big resonated exhaust. Both are the same effect, but 4 cylinders makes a different noise than 6, and the effects of displacement carry through to exhaust note, as do revs.

Do a little research, please, on what causes the sounds you particularly like, because all anyone here can tell you is "well Flowmaster makes mufflers of various sound" and that loud, "throaty" exhausts aren't always better. If you're dead-set on noise alone, just clamp a cheap Cherry Bomb under there and call it a day.

I guess I'm from a different generation. I grew up where any bad*** car or truck worth its salt was very loud. Makes a statement. I shake my head when I see a fully decked out JKU with six inch lift, D-ringed rock bumpers, 35 or 37 inch muds, winch et al rolls by whisper quiet. Makes me kinda laugh.

My magnaflow produces a nice low growl - not obnoxious at all.

A car should only be loud when the hammer is down. You only look and sound like an idiot if you're rolling by at cruise doing 40 and you're shattering windows.

OP already has a flowmaster? The only way to make it "throatier" would be to cut the muffler out entirely and make it stupidly loud all the time.

The 4.0 is not a good-sounding engine and it doesn't have a lot of exhaust volume, so it's difficult to get a good sound out of it without some serious acoustic engineering. Even then, the best notes from the 4.0 come between 3k and 4k, not the range you'd normally want the engine to be in.

My vote is straight pipe through the hood...this always makes it super non ricer and throaty....Or do a 90* upturn into a hole you cut into the floor of the cab, that way you can hear it better when it is throaty....

If 1 flow master sounds good, then 3 in series must sound super good!

Straight pipe

Hopefully this will help your question with no obnoxious playing. I had an old system which I cut the flange off of. I then found some exhaust tubing ( about 2 feet), welded one end to the flange and added a turn down on the end. I took a litle bit of wire mesh, rolled it up, slid it into the pipe and formed the end to block the flow just a little bit to help with back pressure. The steel mesh comes in Different shapes so you can play with or " tune" your pipe to what suites you best.

Note: If you have too little back pressure you'll throw codes when stepping on the pedal while trying to pass someone on the street. It will also pop and sputter while the computer freaks out trying to adjust the mixture.

Now before all the anti-volume, straight pipe haters chime in again, this does give the jeep a low, throaty tone thats not too ear rattling. The reason why I did this with my Jeep is because I didn't want to unintetionally destroy my muffler, which I NEED for smogging every two years, while im playing crawler over rocks. True- it probably won't happen very often or at all for that matter but for me a $15 pipe is easier to fix than a $200 cat back set up. Now I just swap it back and forth when necessary.
