alot of people might disagree but y change out the whole exhaust system to put the same size piping under but with a different muffler and maybe different resonator or none..... when i got my exhaust done i told him wat i was going to do and he said.... u already have a 3'' pipe under y put the same one under just change to a high flow muffler.... and thats wat i did i got a imco and it sounds great...... i heard zoomers borla... and etc.. and the sound really good but is it really worth it... cuz i spent $189 and alot of people notice it... but like i said its just a question

Stock is 2.75" not 3".....

Also how it is bent I believe is different

Granted you are not going to gain big hp for swapping out the cat back, but sound is one something to consider also.

If you want some improved sound and HP gains do the LT header

ok.... make sense but y do everyone say 3'' cuz i thought the same the they say its 3'' with 4'' tips and dont these motor work better off compresstion

borla look sick and sound sick that why I got it

See and hear a Borla S in person and you will see and hear for yourself.

Also the design. The stocker is not a true dual system. It only uses one muffler for both banks. Most aftermarket systems are true dual exhausts with a crossover.

^ +1, true dual, better flow for small hp gains, way better sounds over muffler, and also the tips man, all in all its worth it, thats why people do it, but on a budget , hi flow muffler is great way to go, now get some new tips ;)

I agree thats the cat back exhaust is a waste of money as i havnt seen any hp gains from others who have dynoed with them. Sound dont get the job done in the performance dept. Dam i guess im showing my age lol. All my cars have allways had stock exhaust going from my 426 MAX WEDGE,383 R/R, 340 DUSTER and all performed better than the ones that had aftermarket exhaust. I cant see spending 1200 buxs for noise no matter how great it sounds.

My Magnaflow system uses one muffler. It's not nessacarily true that a one muffler system isn't a true dual. The muffler in the Magna. system is the cross over pipe. Personally, I love my system. Everyone of course loves their own system, don't discourage the single muffler aspect b/c it has it's purpose.

Well don't call me dumb, but I want a borla :D Stocks are nice, but there is always better

Some of you may think a catback is a waste but, when you do other mods, it's essential. A 3" system with h/c, Ported IM, headers.... it's beneficial.

Just installed my Corsa exhaust... I'm in love with my ride all over again! Amazing!!!

Dual exhaust is overrated... the original Race Hemi cars came with headers and single muffler.. they ran 11.20s. ;)

These threads are always interesting to me. So many opinions and choices to review. To you it might be a waste of money, but since you choose not to spend yours, your not wasting it. To someone else who chooses to buy an Rm (?) antenna, LED tails, exhaust, whatever, it is not a waste of money, but a personal choice where to drop their dimes on what floats their boat.

Age has nothing to do with it. For me, started out slapping "Smittys" on back in the early 50's. For me, the B&B sounds better than stock, and the tips are an improvement over stock appearance. My choice, my disposable income, and my smiles everytime I key it up or go WOT.

For you not so much love for non performance items. That's cool too. So I guess too that the dyno sheets many of the exhaust and intake manufacturers post are all lies or marketing hype......Maybe.........don't know. Regardless, the availability of so much aftermarket stuff for us here in the USA, and the ability of the manufacturers to sustain a long term business is a good thing. As usual, it once again boils down to different strokes for different folks. :)

It's not all about performance for everyone, or every member of Sema would only be pushing heads, cams, and other strictly performance stuff. Their would be no Borla, Corsa, B&B, Magnaflow etc.....hp gains or not.

My Borla is worth every penny of the $1,000 it retails for

Every bend and kink hurts performance....Borla is the perfect catback for the Jeeps

Just my opinion

Its depends on why your thinking of buying it. If you wont it for big HP gain, then its a waste of money. If its for the sound, then maybe its worth the money.

Dual exhaust is overrated... the original Race Hemi cars came with headers and single muffler.. they ran 11.20s. ;)

Yeah yeah...I see that cutout up near the headers:D

yeah personally i dont think i am going to go with anything (other then a muffler possibly) unless i get headers... i dont think it is worth the money for 5 horse... i have had some loud cars (shelby z with straight 3' exhaust and mustang GT with X pipe and the LM II catback to name a couple) but for the $/hp its not really worth it to me on the jeep

i like the fact that these jeeps have a nice rumble and when you put down a low 13 or high 12 and they can barely hear it... i think that is huge step from the 1970 nova with uncapped headers running a 12.8 :)

you could buy other mods that give you a bigger kick in the ass...

it's an area game... one 3" can out flow (2) 2"... but it doesnt even look like the picture is that big...

and i bet if they put duals on it you would be running 11.10's... and i bet if it had cats and todays restrictions it would be running 11.6's (on slicks)

Eagle eye.. I thought those were inconspicuous. :D

Chrysler's little secret... if you look closer, the guys would uncork those cutouts, push their Super Stocker's up to the line, fire them up and proceed to blow the doors off Chevys and Fords.

Win on Sunday; sell on Monday, was the motto...

Actually, as the story goes, this was primarily to save weight and costs... because most guys that owned a factory Super Stocker were racers and would take the mufflers off... and therefore no reason to install expensive dual exhaust systems. A little history lesson. ;)

I would be inclined to run a quiet high-flow single exhaust system just for the sleeper factor... as someone said, it's a personal choice. I also believe it's just as cool when you can quietly blow the doors off someone that's making unnecessary noise... just roll up there and smoke 'em.

Didn't someone here just do that against an old Nova making all kinds of racket?

i didn't look that close... :) ... see thats what people should do... they have electronic ones now-a-days...

see thats wat im talking about i like this forum alot.....i brought up a subject and no one up here argue about it..... everyone gave there opinion and thats that... my friend is on a acura forum and he say the argue like lil B#$hes up there... but its nice to see we have grown men and woman if there out up here ..............

but back to the subject how much hp do u really gain from each exhaust system..... i could be wrong but is 10 hp to the wheels really worth $1000-$1400dont get me wrong they all look good but really... i mean if u have the money go for it... how am i to tell wat to do with yall rigs.... its just my opinion.... if i was rich like most of yall up here :D ill do it to.....

To be brutally honest, I did not do it for the HP gain. There's enough there stock. I did it for the sound. LOL yes, its a lot for sound, but hell, I love it.

No sense in the purchase yes.... but where the sense in a 6.1l Hemi equipped Jeep?? LOL

I also put my exhaust on just for the sound. :)

Back in the day we'd install Corvair Turbo mufflers... flowed better than anything on the market during the 60s. Those were made by Walker back then.. I believe now called DynoMax?

OEM Corvair Turbo and Hemi mufflers were the highest flowing in the 60s and 70s... the others just made more noise.

Personally, I would spend my money on a PP Valvebody first... the SRT already has a hi-po exhaust system. This is just like the old days when magazines did muffler shootouts, they never did much for me because I'd always install Corvair mufflers.

If you're going to spend money on exhaust, do something different and spend it on an exhaust system like Dynatech...

I like it when people go off the beaten path; for example, Bassani -- reminds me of my 2-stroke moto-x days. My friend worked there straight out of high school and had a huge Bassani sticker on the side of his '63 Mercury Comet... we called it the "Bassani Car" -- terrorized the neighborhood racing around corners and hitting curbs with dog dish hub caps flying through the air.

you'd wind up in the pokey doing stunts like that today...

Well I went for both, better performance (or better flow) and throatier sound.
Since the stock pipes are 2.75" I went with the Gibson's 3.00" Stainless Steel pipes, the Dynomax Ultraflow X muffler which includes a built in X pipe design and I am not running resonators. And for looks I got the Flowmaster's 5" slant cut rolled edge tips.

With headers, free flow cats, heads and cam I expect this exhaust set up to flow really well and show good results at the track.
