cutting muffler out??

So im looking for an inexpensive way to get a little more sound with out hurting performance. I have a freakin 4 foot long muffler on my 02 Screw 5.4 and it is very quiet. Will cutting out the muffler and replacing it with a pipe hurt anything? I would leave the cats which i think is what gives the back pressure the engine needs...any thoughts????

I wouldn't do it mufflers create your back pressure and help tune your vehichle, no back pressure ruin your valves. Alot of people and muffler shops do just put pipe in cause even with no muffler stock cats make your truck quieter than most people want. I wouldn't do it though.

Not true, I run dual cutouts right off my longtubes on my camaro and never had a problem. To the OP get a dynomax bullet, they are $40 and sound great, its what I have

You can replace the stock muffler with a piece of pipe if you want to. It will NOT hurt anything. I suggest putting a 12" bullet in there though, as it will deepen the sound and tone it down a hair.

Disregard thaus68 reply, as it is false and it is apparent that he knows not what he is talking about. Sorry to be so blunt thaus68, but people come here for accurate information.

So your trying to tell me no back pressure on a stock motor is a goodthing? You know "whatever" everybody has there own opinion I would never just go without some sort of a muffler.

The thing is, I dont want a super loud pipe,,,just something with a some what I like to call "man noise". I looked at some magnaflow instead of the bullet but its more expensive....anyone tried them or know the difference in the too....is magnaflow more money because of the name??? If they give the same sound then I will buy the 40$ bullet.

Magnaflow has a different sound. They are also stainless steel where as the bullets are not. A magnapack ( 14"x4" round muffler ) from magnaflow would also be a great sounding way to go here. If you want it to be more subtle, then choose an oval muffler or go to a Borla Pro XS. But, these are a little higher in price. The bullet has had great success do to the fact that it is a straight threw muffler for max. exhaust velocity, it sounds great, and is really cheap!

simple bullet swap with a 3.5" tip in the stock location or out the side before the rear tire will give you that man sound you want.

Thanks for the bullet video guys! Thats the sound I want.....I noticed you said you have a 3" bullet but my exhaust is 2.5".....should I just stick with the 2.5?

^ He has 3" pipe installed at the end of the y pipe to a 3" in and out bullet, and then a single exit. 3" bullet will sound better, and perform better in mid RPM range. A 2.5" mid pipe will maximize your low end, but mid to upper range will not be so hot.

I recommend running 3", but it's more money too...
