I want to put an exhaust on my Jeep. I am looking to go as cheap as possible. I don't care about drone my intake and system are loud and I love it! Would it be best to just slap on a powerstick? What diam and length etc. would I need? Do I just cut off the muffler and clamp the stick on? My Jeep is a 1999 Jeep Grand Cherokee Laredo I6 4.0L any help would be appreciated! I want growl! <3

A powerstick would give you a loud exhaust note for sure. Im sure there are some you tube videos of people with the 4L engine and a powerstick so you could see how it sounds. As for dimensions of the product, hopefully fellow 4L WJ-ers will chime in for ya.

OK, I looked at that website. Couple of questions...

1.) Are they good for performance?
2.) Does it adequately replace the muffler? (Emissions)
3.) How is it put on? Clamps? Welded?
4.) Are they reliable off road?
5.) Sizes?! What should I put on my 4.0L to get the best sound? (Growl) What inlets, outlets, length and diameter is best for my Jeep?
6.) Is this the ONLY company/website I can get these from? Are they reliable?

Any other ideas/thoughts will help! I just want to be sure which one I should order and how to put it on.

1. yes, minimal restriction, coupled with a nice cold air intake or short ram will make your motor breathe better.

2. I would guess it depends on which state you live in.

3. When my perf. muffler was put on, it was welded so my guess is whatever the shop does if you take it to one.

4. I dont see why not. Small, lightweight, sleek and does not hang down low like the stock muff does.

5. Need a fellow 4L guy to chime in.

6.Looking for input from Joe or other powerstick users if they know.

Hope this helps best i can.

Thank you for your help!

OK, So far, so good!

What I need to know now is...

Q.) Does it adequately replace the muffler? (Emissions)
A. I would guess it depends on which state you live in.

I live in Connecticut. Any ideas as to emissions?

Q.) How is it put on? Clamps? Welded?
A. When my perf. muffler was put on, it was welded so my guess is whatever the shop does if you take it to one.

I am going to do this myself hopefully. Does anyone know if clamps are OK?

Q.) Sizes?! What should I put on my 4.0L to get the best sound? (Growl) What inlets, outlets, length and diamitor is best for my Jeep?
A. Need a fellow 4L guy to chime in.

If anyone knows what is the BEST for inlets, outlets, length and diameter for my I6 4.0L please reply! I want the best growl!

Q.) Is this the ONLY company/website I can get these from? Are they reliable?
A. Looking for input from Joe or other powerstick users if they know.

More info on the company, or if these are sold in other places would help! Thanks!

1.I imagine that a less restrictive muffler will be better than stock, but your not gonna take a second off ur 1/4 mile.

2.Your catalytic converter controls emissions, not the muffler. The Powerstick will be an adequate replacement.

3.Clamps will work just fine, make sure you tighten them enough to do their job and actually clamp down on the metal.

4. I don't see why they wouldn't be adequate for offroad.

5.Your Jeep has a stock 2.5 inch diameter, so unless your going to upgrade all the pipes, you have to get a 2.5 inch inlet/outlet. And once you cut off the old muffler, your going to need at least 22 inches of pipe to fill the gap. A shorter Powerstick will probably be a little louder and harsh and the longer you go will result in a slightly quieter, more mellow tone but still pretty ferocious even on an I6. However, don't expect it to sound like a 60's muscle car, you'll need a V8 for that.:thumbsup:

6.Classicchambered.com is the only place that I know of that sells the powerstick.

Hope that helps!

No problem. And since your doing the install yourself, I'll give you a little extra help. A little over a year ago, the cat on my 93 ZJ failed, and as there are no emissions test in WI, I just decided to replace it with a straight pipe. I went to a local muffler shop and for $10, they cut me the length of pipe that I needed and stretched the inner diameter of the inlet/outlets to just over 2.5 inches so that it slid over the rest of the pipe a little easier. Also, I used a little grease to help slide it into place. After that I just placed the clamps on and cranked 'em tight.

Well, the outside diameter of your pipes is 2.5 inches. It depends on whether or not the inside diameter of the powerstick is also 2.5 inches. If they are measuring the outside diameter of the powerstick at 2.5, then you may need to get it stretched ever so slightly so that it slides over the existing pipes. Or, you could cut a small slit lengthwise down the pipe and compress it a little so the powerstick fits over it.

Just another question, I haven't bought one yet. If the pipes are not setup for Center/Center in and outlets is that a problem? If my muffler(Haven't checked) is Center/Offset then will this Powerstick not go in right? I just want to be able to take the old muffler outta it's clamps and slap the powerstick in after spreading a little.
 
#21 ·
Other than removing the muffler completely, I don't think you can get much louder than that. I feel also that I should mention that you don't absolutely have to stretch the Powerstick to make it fit over your stock pipes. I only mentioned that because I went to muffler shop and had them make my straight pipe custom. I had a 93 Grand and whether or not they have to stretch it to make it fit over your existing pipes depends on the setup that you have right now....

our straight six's don't growl, they have no rumble. your best bet and the best sounding note while being loud is a flowmaster 44 with a magnaflow cat. i have tried all different kinds of mufflers on my buddies 4.0 and that is the best its pretty loud but not annoying and has a good note at all throttle positions.
 
#23 ·
Not to refute you DennyBoy, but I've heard that the flowmaster 44 series has a lot of drone. But that's just what I've heard, so I could be very wrong. I personally have no idea what it sounds like on a straight six so please don't think I know everything.
 
#25 ·
Since you want it ridiculously loud...chop the muffler off and call it a day. A PowerStick or some kinda straight thru bullet style muffler will get rid of the annoying noises that come with a straight pipe.

Its your choice tho. If your system is that loud tho, will you ever be able to hear the exhaust??

Listen to Hannes, he is the WJ exhaust God, lol.:thumbsup:
 
#27 ·
If I chop the muffler off it would be illegal. Connecticut requires a muffler of some kind and no more than like 72DB from 50 feet from the exhaust. I sent you a PM Hannes about if it is possible to add the powerstick even tho the outlet of the old muffler is offset and the pipes are not and even line to each other. It looks like this in the back ______--------. Will there be a problem pulling one of the pipes to the side? Is that even possible without breaking something?
