I have a 97 4.6L F150 and currently have no muffler and it goes from a single pipe to dual pipes out the back. I don't know which size borla muffler is the best to get. I haven't decided if I want to stay with the duals or just change it to a single outlet out the passenger side yet. I don't want to make a mistake and get the wrong size that turns out to be the size for the car. There are so many choices. I really like the dual exhaust but I might have it changed to side exits or 45s instead of straight out the back.
Ive heard of the Borla XR-1 and others but which one!?!?!?!?
And which inlet-outlet size do I get?
And should I get SIDO if I want to stick with my duals?

Thanks for any help guys

 

whats the reason for the change? you want it quieter?

 

Yes quieter maybe a deeper crisper sound with no crackling. Don't want it too quiet though the current setup is too loud because of no muffler.

 

well then dont go with a single exit, you can hardly hear it.

i would guess to go with the smaller xr1 muffler. that should quieten down on the crackling.

 

How about Sido xr1 12 inch long oval body or should I get a longer oval body

 

I have Borla Pro Xs mufflers on my truck... Makes me smile everytime I crank it up. Not loud and obnoxious, but great deep tone and no drone.

 

thanks guys

 

Which one of these? Im not running true duals. Would it be bad to run a dual in dual out after the y pipe because Im leaning that way.

dang those borlas are expensive!

DI/DO muffler seems ridiculous if you arent running true duals.

just grab a SI/DO and replace the Y with that.

 

Jegs.com has the 3" Borla XR1 Bullets em for like $130 for a muffler. Not bad if you ask me...

Here's the link: http://www.jegs.com/p/Borla/Borla-XR...44683/10002/-1
Of course you can search around for others on there. Why buy directly from BORLA when you get em' cheaper from somebody else?
