is there any magnaflow muffler that is louder than the orignal 40 series flowmaster. that has a nice rumble to it and is pretty loud for a 4.2l. thanks

Magnaflow's tiny race mufflers are louder, but come in larger pipe size than you need. Try a Dynomax 4" round by 12" long bullet race muffler.

 

would that muffler be illegal???

 

I don't know how strict your jurisdiction is, but here in Texas they look to see that your muffler is "there". This muffler design looks like a number of other mufflers. I've seen them pass inspection here many times. They don't look any stranger than a glasspack. I doubt they will ask about manufacturing specifications and measure decibel levels.

 

o well i just took my truck to the muffler shop today and there going to put something on for me that is loud. hope that it is when i get it tomorro. well ill let u know how it sounds.

 

Ok, good luck. "Hey mister, make it loud !".....good approach.

 

i just got my exhaust on yesterday and it sounds good for a 4.2l. my friends said it sounded nice and pretty loud. i just dont really know what kind of muffler it is. i think it is some kind of glasspack or something. it looks like a tube and has two y connectors on the ends of it. when i find out what it is ill let u know.

 

Interesting....after you've tried it a while and figure out what it is, fill me in.

 

Have 2003 4.2 standard,,,,,put on flowmaster50 (one in and two out). Sounds better than stock,,,,,nice low rumble,,, dont crackle and pop either,,,,,

Adding K&N intake kit this week,,,,an really wondering how the truck will sound overall!

 

i found out what my exhaust is.... it is a glass pack. im going to get the cats cut off some time to make it louder. i can really feel the hp and torque i gained. me and my friend raced last night and i let him get a head start a little but. he has a gmc truck with sraight pipes on it and has a 5.4 engine. and i still beat him. once i got passed him he started to slow down. he said " once u passed me i new i wasnt going to catch up". so i love my exhaust i just wished it was a little bit louder. but it is fine the way it is.

 

From your initial description, I thought it would be a glasspack. I'm glad you're enjoying it.

 

after awhile the exhaust will get louder wont it? once it gets broken in pretty good??

 

I have a Flowmaster 50 with 3" in/out on a 2003 5.4L FX4. I put it in place of the stock muffler and I used all the factory pipe. The shop did a great job getting the factory 2.5 pipe to work with the 3" and it sounds great all for 80.00. Iam happy with it, but I read about the loss of torgue over a Maganflow. I just wondered if this type of mod is popular enough for any feedback?? Is there any info in regards to there actually being a loss of torque, because i didnt go with a 500.00 exhaust system???

 

hey hillbilly, i saw that u posted before u wanted to go for the straight pipe look. is that what u ended up with or did they just put the glasspack on. if so, how much $$$ was it?
thx

 

Glasspacks do get somewhat louder over time.
