Triple88a for mine i got an adapter 2.5 to 2.25 and welded one on each side.. Its much easier to switch to a bigger pipe later if the muffler has bigger outlets otherwise you will have to cut the outlets off... Give me some time and i will tell you if there is any difference from stock tailpiping to 2.5 piping.
with stock tail piping its just barely louder than stock. If you are planning on upgrading your cat to high low id get the 2.5" intlet with an adapter.. i will install my tail pipe sometime next week and will let you know how it sounds

thanks...the tailpipe is stock...only difference is the tip is a 3"...not sure if your hitch would interfere or not


part of the reason i kept the stock pipe was i had heard backpressure issues with larger pipes...
03-29-2007 09:41 AM
stevin33 so if i were to order a flowmaster with 2 1/2" inlet/ outlet and i wouldn't have a problem with the fitment? even if stock pipes are 2 1/4" from the cat back?
sorry about all the question....
guess i'm a bit anal and would hate to go thru all the bull$hit if i were to order the wrong part.......

Triple88a Bigjeep no flowmasters from those videos.. all i was tryign to say is 4 bangers can sound good also.. It just depends what you like..

BSing yeah...ill never grow to like the 4banger sound. Unless its an old flat four off a jeep.
03-28-2007 09:34 PM
mrbigjeep those aren't flowmasters though are they?...and they still sound like 4bangers
03-28-2007 06:54 PM
Triple88a The stock setup on a wrangler is single 2.25" center intlet and single 2.25" side outlet. I know eventually i will replace the catalystic converter and tailpipe with 2.5 so i got a 2.5 intlet and 2.5 outlet and am now just using adapters to make it fit right.

Triple88a I will let you know as soon as i install my 2.5 on my delta. I'm preatty sure it will be louder but i dont know if the depth will change.

Bigjeep i used to have a 1.8 Miata before i got a wrangler.. i had a cat back on it with dual tips.. it sounded great actually. It really depends what you like so.. I bet you got the impression that a 4 banger engine sounds horable because most of the 4 bangers are ricers with cheap coke can mufflers you find at autozone or pepboys. When you see a good catback (not just a muffler in the end) you will see what i'm talking about.

Both are 4 bangers

stevin33 other than backflow pressure, does the diameter of the tailpipe affect the sound? for example, would the 50 delta become louder with a 2 1/2" tailpipe opposed to the 2 1/4 or 2 1/8"? and the same goes for the 40...
i checked out the flowmaster website and noticed that there are different inlet/outlet set-ups. which one would fit properly?
03-28-2007 09:38 AM
mrbigjeep i didn't read all that....but lets just say the flowmaster doesn't sound the best on a 4banger....but neither does any other muffler so no worries...it definitely sounds good on the 4.0 though

i may be echoing his statements
03-28-2007 08:43 AM
Triple88a yes the 40 is a bit louder but its also higher pitched.. the lenght of the tail pipe can also control the loudness of the muffler.
The 50 delta is lower pitched so its deeper and a bit quieter but if you dont have a tailpipe installed it is loud as hell.. i didnt install my tailpipe when i first installed my delta so it shook my seats at idle so it was way too loud and was probably going to get a ticket so i installed my stock tail pipe, sometime soon i will install a 2.5" tailpipe that i have laying around and ditch the stock 2.125 (1/8)".
If you want your muffler to be loud you can probably cut your stock tailpipe and it will get a bit louder with stock muffler but i dont know if it will sound nice..

Yes 4.0 is a big engine.. let say you install a flowmaster on a civic.. it will sound like crap.. i used to work right next to a tune up shop where guys installed turbos, nitrous, exhausts, all sorts of goodies on sports cars and they make a civic sound better than z350s and infinities, they also made a 240sx sound like a corvette lol Many people say oh civics normally sound like crap.. well thats only with a ricers can.. if you get a quality catback instlaled it sounds perfect althought people will still say its crap just because its a civic.

Id say anything bellow 3.0 or is not domestic design shouldnt have a flowmaster.. domectic cars are made to take in fuel (same strategy since the 50s) no matter what so they sound good while foreign cars are made to be more economic so many use way different systems than american cars have therefore flowmaster on a japanese sports car sounds like crap. Keep in mind that japanese sports cars have smaller engines (6 is preatty much the biggest engine they use) but they are light as well to make up for it compared to the V8 4k lb corvettes
03-28-2007 06:07 AM
stevin33 now the 40 is slightly louder/throatier than the 50..??
or do i have it the other way around?
and when you say a big engine, are you refering to the 4.0?

Triple88a I love the sound of open hearders.. too bad its too loud if i run it on a trail somewhere you will hear me in massachusetts lol.
03-27-2007 12:06 PM
cnt487 I gotta agree with TX on the Dynomax. I just installed one on my 98 TJ and I'm quite pleased.
03-27-2007 10:22 AM
jp'rs_peep'rs c'mon

Save the money!
Run on down to your loc'l stab and grab and get yourself a cheap china bob made muffler system for 99.99 and put that de'r on. Because you'll prob rip it off out in the brush.

stevin33 c'mon now.....
you know what a good sounding jeep sounds like when you hear one.....
something that doesn't sound like a honda civic w/ a folgers coffee can for an exhaust.

03-10-2007 09:51 AM
TXST8tj i'm personally a fan of Dynomax.
03-09-2007 11:29 PM
Triple88a When i was shopping for an exhaust i did look at Magnaflow but i didnt want my TJ to sound like my old sports car so i skipped it.

Take a listen (clip 1 and clip 2)

03-09-2007 10:27 PM
AzTJ what about magnaflow? I have a couple of Jeep'n friend that run them and they sound great!
03-09-2007 09:24 PM
Triple88a i got a 50.. I have the stock tailpipe on but its quite low. If i had the choise i would get the 40 since its a bit higher pitched. As loudnes goes the tailpipe makes difference in that. Shourt pipe will be really loud. When i installed my 50 delta i did not install the tailpipe and it was loud enough to shake my seats at idle. The only problem i had with my muffler was i had to cut the stock tailpipe off since i couldnt get it out and also the clamp in front of the muffler (by the catalystic converter) in preatty bad shape so i had to cut it and then had to use a tool to rip off the stock muffler since it the clamp was so tignt on there it actually deformed both pipes with little humps.

TXST8tj the 40 is going to be a bit louder, and probably have a better tone overall. to get a similar effect as the 40 series, the 50 series really is best on a larger engine.

there are better mufflers out there, but flowmaster like other product brands are household names and usually get the uneducated vote. people buy brands they hear a lot, even if it's crap such as sony products. flowmaster isn't crap, but it's not the greatest thing since sliced bread. i'll tell you, i'd buy flowmaster before i bought borla though.
03-09-2007 11:11 AM
stevin33 seems as if most people lean towards the flowmaster.
does anyone know what the difference between the flowmaster 40 and the 50's are?
02-24-2007 09:46 AM
Buster I have been running the Borla catback for about 3 years with no problems. I would not recommend ths Borla header tho...like Tdad said, it is over priced and has some fit issues (especially in the 97 to 99 years). Just my .02
02-22-2007 08:34 PM
Tdad I have a full Borla exhaust. If it ever needs replacing it won't be with another Borla system. Poorly designed, poor fitting and overpriced, IMO.
I'd look at Flowmaster or Magnaflow.
02-22-2007 04:11 PM
TXST8tj Borla?

most of the systems made for TJs are pretty easy to install with the clamps and stuff. personally, i prefer a welded exhaust system. cost more to do, but there are less issues down the line.

the borla exhaust isn't very loud, but has a decent sound. a dynomax or flowmaster muffler are going to be louder and deeper if that's something you're looking for.
economy-wise, you probably won't notice much, if any difference in mpg savings.
power, you might notice a little seat of the pants power.
