2012 Jk stright piped?
 
Good or bad idea opinions? Want a loud rumble. Don't want to break the bank too many other jeep things to get.

I tried a straight pipe with cat on my 2010, it sounds loud and rough and eventually I put the muffler back on. You're better off getting a different muffler and avoiding the potential ticket.

tabber02 08-29-2013 07:28 AM

a nice compromise might be the addition of a resonator... dynomax race bullet perhaps... it's what i'm running... :whistling:

HardCase 08-29-2013 07:31 AM

I'm not much of a wrench, can bolt on pieces of armor and change out wheels but that's about it. But I've been told that a straight pipe screws with certain engine settings or balances and can adversely effect performance or even cause damage over a long term. Is that correct?

tabber02 08-29-2013 07:39 AM

yes. the short answer is... the R&D folks design the length of the exhaust help tune the engine for the ideal back pressure and gain some fuel efficiency.. in the long run, if you remove a part of your exhaust... you'll probably experience worse gas mileage and you run the potential of fouling your spark plugs (not likely... but could happen).

the ways around that are to purchase a tuner, or take your rig to a shop where they can dyno it and tune the exhaust and intake... but, alas, it's a jeep... let's be honest -- most folks just want a little more noise. :whistling: and aren't going to bring their rigs to a speed shop...

So your running straight throw the dyno and out the exhaust?

HunterTheBeagle 08-29-2013 08:57 AM

This is just a suggestion but maybe you should look into the pypes system for the jeep. It looks like a pretty strait thru design plus its stainless, when I was looking at exhausts I saw a video of it (I think on their site) and it sounded super loud. That's really all I know about it but it maybe just what you looking for.

Here is the amazon link.

Keep in mind your 2012 engine will 'rumble' less than one of the responder's 2010 does. The 2012+ pentastar engine is a mass production efficient passenger vehicle engine. It's built to please the masses who buy regular vehicles. In no way should you think it is unique to the rugged wrangler. It's not. No amount of exhaust work will ever make it rumble.

You might end up sounding like a giant bumble bee, in fact.

overblown 08-29-2013 12:42 PM

That would sound pretty awful I'd think. This isn't a V8, it's a silky smooth v6. It will never rumble, no matter what you do to the exhaust. You'll only make it louder. And I suspect not in a good way either.

That about sums it up.

X2. I would be embarrassed to drive that thing

razdds2 08-29-2013 01:26 PM

the 2010 sounds much better without a muffler, as that is what I tried to do for about a week before getting tired of it. Don't go for the loudest, go for the best sounding!

2five22 08-29-2013 01:30 PM

:rolleyes:

Straight pipes are fine on a race vehicle that runs at W.O.T. or a 1950's rat flathead Ford powered roadster, but a Jeep?

Expect a lousy experience.

wrangler49009 08-29-2013 01:31 PM

You can always go for a hemi swamp...lol.

Sorry it's a boring day at work.

JKjingle 08-29-2013 01:46 PM

I was installing the teraflex exhaust spacer and broke 3/4 bolts, drove it to an exhaust shop to fix my mistake and it was awful! I do not recommend at all

genesis151 08-29-2013 02:04 PM

Yeah I want the hemi, but the point was cheap solution for better sound

overblown 08-29-2013 05:11 PM

Well now you know that straight pipes aren't it!

ohioviper 08-29-2013 05:22 PM

I bet the 3.6 wouldnt sound too bad with smaller pipes with a dual outlet at rear bumper.
The old 4.3s didnt sound too bad with straight pipe duals if you used smaller pipe like 2".

overblown 08-29-2013 06:41 PM

I think the problem is that some guys think they can get that V8 type rumble and sound out of these 6 bangers and that is just NOT going to happen no matter what.

genesis151 08-29-2013 09:31 PM

Some people get so worked up. I straight piped it sounds better then stock. I'm gonna have to figure out how it get a little more rumble. I'm gonna try a resonator. If guys in little Hondas can make there little motors rumble I can do it to a straight 6

bmwsma 08-29-2013 09:41 PM

Bad idea. Gonna sound like sh!t and be loud as hell

genesis151 08-29-2013 09:49 PM

What did you do^

Some people just don't listen. The 3.6 doesn't rumble, guys in little hondas don't rumble. They just buzz and fart. If you want a fartier/buzzier exhaust note than you are well on your way I'd imagine. Also, you don't have a straight 6, you have a V6.

genesis151 08-29-2013 11:04 PM

Okay thanks

:rofl:

well i have a resonator installed on my rig, and to be perfectly honest, i love it.... i like the sound of it. especially in the woods on the trail :whistling: and probably the best benefit of not having the muffler right under the back is more clearance. :thumb: and clearance is a good thing....

Reminds me of that Allstate commercial where the guy's Harley sounds like a weed whacker.

OHC engines typically don't rumble as much as push rod engines.
