Default Slp Lm2, But What Headers And Y-pipe?

My Exhaust Is A Nice Sound Right Now But I Want To Add Headers And Y-pipe But Wondering Which Ones Will Give Me The Most Power And I Also Don't Want To Be Obnoxiously Loud But I Do Like It A Little Loud. The Lm2 Is Loud But Only At Wot So I Need Opinions.

You would wanna keep a catted y because an ORY would be really raspy and loud. But at least you have LM2 which is quieter then LM1, but I like mine raspy as hell.

any of the slp stuff is loud as hell with headers on the cars and personally sounds horrible like that. You can have the same performance with a decent muffler and it wont sound like generic noise, so why not?

Do headers first then make your decision Weve have cars that run 8s thru the mufflers, so they arent a restriction if its quality stuff, or set up right. Well worth it, because no one keeps a loud mouth for long unless its a stock car with manifolds
