Yesterday, I heard a loud "pop" while cruising at 60mph. Pull into a rest stop and and discovered a hole in the muffler. The engine now idled roughly, but seem to smooth out about 2000 rpm.
Question for the experts: can the loss of a muffler cause the engine to run rough? It's a 460cid in a '77 F350.
i have my 4 inch exhaust pipe cut just behind the rear of the cab right now with no muffler. If i cut it further up maybe jsut under the front seat or so what would this to the sound? would it make it deeper or louder?

View 14 RepliesWas just mulling over redoing part of the exhaust system on my truck. As it stands the original y-pipe is still intact but some bozo reduced the rest of the system down to 2.25 inch with an ancient glasspack for a muffler. Maybe he thought it would net some kind of benefit, maybe he was just throwing together parts from his backyard. Either way it's going, I'm planning to keep the Y-pipe but step it up to 3 inch with a Flowmaster chambered muffler and I just suddenly wondered if the position of the muffler in the system affects performance. If I put it directly after the Y-pipe the exhaust pulses would hit it sooner...
View 14 Repliesi plan on getting rid of either the cat or the muffler probly in about a week...which one would be better to lose?
i dont care about the sound cause either way i go if i keep one it shouldnt get much louder right and either one will increase power/torque... im wondering which one bill better my mpgs the most im leaning towards muffler it will be easier and more legal...then again my truck already passed inspection
I just got a Walker SoundFX muffler and there is no drain hole for condensation. Should I make one?
View 3 RepliesI have an 2003 Explorer 4.0 and I am looking at replacing my muffler. Only problem is I don't know who to go with. I am looking for a mellow tone with minimal interior noise. I have been looking at Flowmaster, Magnaflow & Dynomax although I can't make a decision. I have heard how the 4.0 Ranger sound's on Magnaflows website(sound's OK) aside from all the horrible sound clips floating around that don't have good quality to listen too. I was looking at Flowmaster 50 series Delta Flow and there SUV muffler(a tad thicker than Delta series) but want some feedback on who/what to go with. Also, right before the tailpipe ends, next to the spare tire underneath, there looks to be what looks like a resonator if I am correct on the tailpipe. Can this be removed and replaced with new piping? Will it hurt performance or make the exhaust sound different?

View 5 RepliesI have a 94 ranger 4L. I am looking for a more loud exhaust sound in/outside the truck and at idle. I have had a cherry bomb turbo on it and it was ok but not loud enough for my liking. I just picked up a flowmaster 40 2 days ago and it sounds good but again just not loud enough for my taste and kinda a lot more. I was looking for a louder muffler that is not a glasspack and would like to stay under like 80 or so.
I also thought about getting a high flow cat which i think might make some more sound but was not sure. Im running the stock pipe which is 2" and end in back of the wheel on the right. I look at the Hooker Headers Maximum Flow Muffler which i thought would be louder b/c it's more straight through the muffler so it would put off more sound better. What would u recommend for something more loud ?
How many O2 sensors does a 2.3 fi 4 cyl. have. I think just one on the manifold, but I'm not completely sure. Engine is running very rough and seems to miss at low RPMs, has no power and drinks gas like crazy!!! Emissions light is on on the dash. I'm thinking O2 sensor......tried replacing, but couldn't get enough torque on the sensor socket wrench to loosen, may be rusted.
View 6 RepliesI just purchased a 2003 V10 with 270 000kms. The truck had had regular maintenance. It has an exhaust leak and runs a little bit rough. Could the exhaust leak cause the truck to run a little rough or am I dealing with another issue?
View 2 RepliesI have a 1992 SC Coupe I was just given for free from my Cousin. It has 92, 000 miles on it. The car looks in great shape, it drives smooth. But in the front under the hood there is a loud engine noise almost like there is no muffler on the car, you acutally hear it loud inside th car also. But the sound is in the front. After about 15 min of warming up the car the sound is gone. A freind suggested there could be a crack in the manifold.

View 11 RepliesI've got a 2006 6.0 350 with stock exhaust and am wanting to either delete the cat or the muffler, but not both. I'm curious how each would sound? For example, would deleting the cat make it louder than deleting the muffler, or will one make the turbo whine more audible than the other? Also, is there any benefit to deleting one over the other, performance wise? Oh, I'm not really looking for loud and obnoxious, but more turbo whine wouldn't be too bad .
View 2 RepliesI have a 94 f150 with the 351 and i was wondering how loud it would be with that huge stock muffler cut off and jsut the two cats still in place. I heard the cats will still quite it down a little bit cuz I don't want anything obnoxiously loud...

View 10 RepliesAfter hearing some loud noise coming from my exhaust system, it was determined that there is a hole (from rust) in part of the cat. assembly. Three shops advised for replacement, there are no aftermarket products for this unit. I have NOT gotten any error codes, the only problem is the noise. What to do? The car is 10 years old with 86000 miles. I have been reading about some of you getting just the one piece and having it welded on, but I do not believe any of the shops here will do that, and indicated that it would be a very temporary fix.
View 17 RepliesMy 1999 F-150 came with a horrible performance muffler on it. It is pretty quiet at idle, but off idle it is just too loud.
It is one of those weld-in, cylindrical, red ones. I want OEM sound or quieter, but quality.
How will a muffler delete on stock exhaust sound? I don't want to remove the cat because I don't want it to be too loud. I want it to sound good but not too much whistle (considering my truck is a 2003 the whistle would be very loud) Should I just to a delete pipe on the stock exhaust, or do a cat-back 4 inch straight pipe? what will sound better? Also doing the cat back exhaust will cost a lot more.. but is it worth it? What I should do.
