I have a 2008 dodge ram 5.7.. And I want to keep my stock exhaust system and I want to get electric cut outs. Anyone know website that sells exactly what I'm looking for?? And any place to install in Los Angeles?

 

DMH Performance sell the best there are and have the best warranty.

As for install.......youre just gonna have to call some local shops

 

you could google raceland cutouts they have a cool little wireless keyring remote

 

How much would this run me? Is it super loud with the valve open?

 

what size pipe would i need to buy. 2.5" or 3"

 

+Yes....it's super loud and the level is dependant, on where you site the cut out - before or after the cats.
Also, it's simply THE best $ per mod you will ever spend.
It's not going to give you a shattering performance increase........but it will make you fall in love with your truck all over again and puit the BIGGEST smile on your face lol.
Al.

 

If you have your stock exh then you need a 3" cutout.

The bad thing about Raceland is they are either open all the way or closed all the way. With the DMH you can adjust how open or closed it is so you can alter to noise level and tone. DMH has a 4 year warranty on theirs whereas Raceland is no where near that.
