I have a 1997 4.6l f150 stepside and Im thinking about putting something on it but im not sure what, Im thinking a y pipe behind an aftermarket muffler but I dont know what kind.

Or if you guys have any suggestions let me know, Im looking for a real aggressive sound.

What is the best option and what will it do as far as my power and gas mileage

 

go with the true dual with the 40s. thats what i go check out the clips

How much does something like that cost?

What will it do for power and gas mileage?
Also is it emissions legal?

 

i payed like $500 or close to that and i also have passetter shorty headers. no it is not smog leagle yet i just got a pair of high flow cats yesterday i hope to have them on this weekend. ill post a new sound clip after in done. and i didnt notice mialage going up or down it stayed about the same

 

Magnaflow.

 

 

If you want agressive check out the Cherry Bomb EXTREME muffler. Thats what I got on my 97 with the 4.6 and it sounds good! It was louder then my buddies 5.4 with glasspacks and better sounding.

 

I just had my Cherry Bomb Extreme 3"si/so installed with a 3.5" magnaflow stainless tip and wow... I absolutely love the sound, its very deep and aggressive. pics and sound clips soon to come!
