Exhaust, De-Cat. Piper.

  1. #1
    Right. I want to fit the 4" Slash Cut Back Box From Piper to my 1998 Saxo VTR.

    For best performance i understand i need a good 4-2-1 Man. Though im still bit confused about the bits in between. Have Read the FAQ,s just need some more advice.

    Question. Can i De-Cat it and take out the middle box or will this affect performace?? Whats the best set up for me?

    Thanks

    Rep Will Be Given

    yeh if u de-cat u will get more performance as the gases are gettin out the car faster, get a raceland or supersprint 421 mani, i wud recomend a supersprint centre section too

    ok thanks, would the supersprint centre section have a middle box in it or would it be a pipe from the cat to the back box?

    just a straight through pipe mate

    ideal. i always thought that with no cat and no middle box that would affect back pressure and make performance worse. though ill trust you

    dont get me rong it sounds amazing but if you get a long noise drone within a gear its a bit annoying after a while lol vibrates the whole car a bit lol well mine does

    I'm in the same boat as you, I don't want a noisy car, something that just burbles abit but I do want to decat and 4-2-1 it. Guess the two don't go together.

    I know they don't look great on Saxo's but coming from the Peugeot side of the fence, the Pug Sports are a fantastic exhaust. They've got no cat in them and give the perfect noise - quiet when you're being sensible and raspy when you floor it. I prefer that to some of the more drony/boomy back boxes IMO

    I don´t agree, I think the manifold is better the one made by raceland, it has better steel and in the inner part it´s done a lot better than ss...don´t get me wrong ss is really good, but raceland is a little bit better and it costs the half!
