Ok, I have a 93 Ranger with the 4.0 and its time for a new exhaust system. Anyway, I have decided to just buy a muffler and have my local exhaust shop do all the work. I have narrowed it down to these mufflers.

1. Magnaflow round 2.5" in/out (stainless) $69.99
2. Dynomax Ultra Flow round 2.5" in/out (aluminized) $73.99
3. Moroso spiral flow 2.5" in/out (untreated steel?) $46.99
4. Flowmaster 40-series 2.5" in/out (aluminized) $59.99
5. other (you guys suggest) ***up to $75***

I will have a 2.5" single aluminized pipe ran after the converter with a single stainless exhaust tip exiting after the passenger rear tire.
PLEASE DON'T SUGGEST GLASSPACKS BECAUSE THAT'S JUST GAY!

 

Supertrapp?

Naw, I'd probably go with a Flowmaster.

 

borla sounds better than the flowmasters. and they make headders too!
or gibson

 

I have a magna flow on mine went to an indy shop that does performance stuff and he made the system from the Y pipe back 2.5. Put in a high flow cat the magna flow muffler and he kept bends to a minimum and fairly small so that it would breath better.

I also have a street smart intake kit. Truck runs extremely well and I have been aske if I have a 5.0 motor!

 

two words MAGNA FLOW answer your question.....

 

F L O W M A S T E R !

 

flowmaster

 

I have a Vortec, Basicly a flowmaster, it was much cheaper and it sounds great. I will be doing a cat back spilt and headers next winter.

 

Even my dinky 4 banger with a flowmaster and 2.5" cat back sounds pretty nice. Once I figure out how, I'll record my truck from take off to 60mph at high revs and post it on my website.

 

Alright guys good suggestions. Should I run a Y-pipe and duals that come out under the bumper or stay with a single?

 

I say Flowmaster too, I just put 2 1/2" from the cat back on my '03 4.0 with a 40 Series flow in about the same location as the stock muffler and it sounds pretty killer. I'm not really used to the sound of 6 cyl. engines with a good muffler beings I come primarily from a V8 background but it sounds pretty tough especially on compression, it has kind of a cool girgle to it.

Dual -vs- Single: tough choice.... my personal thought is that unless you plan on doing a fair amount of over hauling to the engine in turn requiring more room for gas escape go for it but you could get away with dual 2" pipes easy. I'm also kind of partial to low end torque which you will lose some of as you open up the exhaust more. I think the only way I would go dual out is if I had headers on mine and could run each bank back on it's own with maybe an H-Pipe or something, that would give it a cool sound and allow each cylinder hit to resonate down the pipes making more of a mini V8 throaty sound but until I do that I'm real happy with the single out 2 1/2". Just my 2 cents. Have a good one guys!!!

 

There was a recent article in Off Road magazine I think it was and it was on duals vs single. Basically if stock go with single, duals if lotsa performance work done. Seems that if there is no crossover pipe duals leave some to be desired as they cannot scavage the exhaust efficiently.

 

i was wondering what other kinds of engine mods you have done. i am considering a Flowmaster and plan on installing an FIPK in the future. what kind of sound could i expect from a 3.0 with 40 or 50 series and where should the pipes end(in front of rear tire or behind)? any idea how much hp/torque i could expect to gain? one more thing... would you recommend drilling holes in the airbox around or under the air filter or both? thanx.

 

At this point the only mods I have done are the FIPK kit and the Exhaust. I have been thinking about upgrading the MAF next but at this point I've got a few other things I'd rather spend my money on. In all actuality I am a little nervous about doing a whole lot more in fear of voiding my warranty. Oh, I've started running Synthetic motor oil, a lot of people call B.S. on me but I seriously thought I noticed a slight performance change and I'm positive I saw a slight mileage increase.

In regards to the tail pipes; in my opinion it sort of depends on what you may be doing with the truck. I've always liked the sound of dual pipes out the back, it just sounds good to hear a muffled roar coming down the road at you and then as the vehicle passes hear the true sound and crackle of the exhaust coming full force out the back. It also helps to keep the noise down in the cab. The only bad thing about pipes out the back is if you are going to be off roading a lot. If you plan on taking some steep terrain where you may drag the back bumper then you can kiss your exhaust tips good bye and have to deal with un-smashing the tips so that you have the power to get home. Sounds funny but I actually had a CJ that had dual pipes out the rear and this very thing happened, it totally sucked. So this leaves you with in front or in back of the tire.... kind of a toss up but I have heard of people dumping them in font of the tire and having the same problems as mentioned above. Basically they get stuck and high center and just munch there exhaust. The alternative is behind the tire and it's a good one. Since the body line rises behind the tire you can hug your pipes in kind of high making it nearly impossible to damage them unless you throw a log up and hook one or something - pretty unlikely. I'm not real sure on the HP but supposedly I gained round about 15HP and 22 ft lb's of torque with the FIPK kit and like 10HP and 6 ft lb's of torque with the exhaust change but it's an exponential increase. I mean the torque went down a bit at low end but the mid to upper end (3500rpm and up) torque increases a bit.

I don't really know how to describe the sound other than maybe a deep beefy Honda with a good tip during acceleration. On average it sounds similiar to a V8 but with a higher tone, not quite the rumble or deep resonant sound. It still has a little resonation but with a higher frequency. On deceleration it kind of has a cool mid toned slightly resonant girgle sound, it's kind of cool. It's not exactly the sound I expected since I had V8 sounds in my head but now that I've listened to it more it sounds like a burly little V6, which is all I should have expected. Know what I mean?

Punching holes in the air box..... herm..... wouldn't hurt I guess, you'll get more heated air off of the motor but I think that is small potatoes compared to just the matter of getting more air - no matter whether it's hot or cold. I never really looked but you may just look at the option of opening up the airways in the existing box. The only thing I can really say bad about this is that it's not going to help much other than maybe for the first 1000 miles you put on a new filter. The biggest problem I had in addition to just a lack of capacity for air flow was I was plugging up filters like crazy. Granted, I spend a lot of time in the mountains on the weekends but heck I could see very noticable build up at every religiously done 3000 mile oil change so I replace my air filter with every oil change. There just isn't nearly the surface area of filter available with those stock square style filters as there is on the cone shaped filters so they plug up faster and get 'flooded' with air faster than the larger ones.

Well my fingers are sore, I'm backin' out.......
