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 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 14 RepliesYesterday, 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'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 1 RepliesWant to install exhaust system on my 06 F350.Tell me,what is the best brand for my truck,I know, very good intake system is from K&N,what about exhaust?
View 10 RepliesHow 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.
View 4 RepliesHave the APR RSC exhaust - developed rattles, specifically in one of the RSC muffler chambers?
I've had my exhaust installed for almost 6 months. About 2-3 months ago, I noticed a rattle from under the car somewhere. I finally got underneath the car a few weeks ago to check it out and the rattle is most definitely coming from the rear RSC muffler (right before the exhaust tips). I'm positive that's the source and I'm guessing that the welds inside for the baffles / walls that compose the RSC technology failed, and a piece is now rattling around inside. It only rattles at low RPM, but it's loud (especially in a parking garage) and super embarrassing.
I noticed liquid leaking from the area between the B exhaust pipe and the muffler. The B exhaust pipe is simply the long exhaust pipe that attaches to the A pipe, or center exhaust pipe near the front. I think the leak is water. It's a slow leak/drip that appears to be coming from the gasket. I have a 1.6L 1998 Honda Civic DX.
View 6 RepliesNoticed the condensation from the exhaust seems to only exit on the left muffler when the vehicle is idling?
Is there an actuator that turns the right side unit on under heavier acceleration?
BMW uses an actuator on their exhaust system that opens up to create more airflow when above a certain RPM.
About 4 weeks ago my 2015 sports turbo developed loud exhaust, deep rumble, dealer replaced left rear muffler. Noise still there. I'm suspecting the center muffler.
View 5 RepliesI tore it apart and there was no gasket or donut ring in the flange. Is there supposed to be a gasket or donut ring? I can feel the leak with my hand. I have retightened & it still "tick-ticks" real bad.
View 7 RepliesI have a 90 bronco with a efi 351w and im missing one nut for the manifold to exhaust pipe flange. I have looked all over the net and can't find the size I know its a 1/2in socket but I need the thread pitch and size, had the parts guy try to sell me the stud and nut kit seem really expensive for just a nut and to install the full kit I have to pull skid plates and the trany supports just to start to get room to do the job, seems like a lot of work to replace 1 nut...
View 1 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 RepliesMy F150 exhaust seems rather quiet when I first start it up, but after it gets warmed up good, the exhaust is much louder (which I like). I started wondering if I had a crack up front that widened out when it got hot, so looked under it when I got home today with it hot and still idling, but didn't see any cracks. Also I did not hear any noise like a leak. All sound was coming from the side exit pipe. So... what is the phenomenon that would cause this?

View 5 RepliesOk, probably about 1/3 times i start my 96 f150 4.9 with true duals, the left pipe has a higher pitched howling noise, its a steady tone whether I rev the truck up or not it just gets louder. It will do it for about 6 seconds and then stop. The truck doesn't run badly because of it, but i took her to autozone to get her scanned and they said that the oxygen sensor on the first manifold bank has a slow response on startup. Is that what causes this strange noise, I don't even know how it would make it, it sounds much different from the engine. The right pipe doesn't do anything.
