raceland 4 2 1 sound ???

  1. #1
    Does fitting a raceland 4 2 1 manifold make any difference in sound to the exhaust, i have some type of large non standard backbox on my vtr and was wondering what difference a 4 2 1 will make. Also does the lamba sensor screww into the 4 2 1 manifold. Cheers

    Not much differnce in sound mate, well there wasnt when i fitted my GMC 4-1 and i have a peco back box, the real noise comes when you remove the cat and silencers, plus u can easily feel the extra power

    imo it makes it the sound more aggresive higher up the rev range

    and the lambda screws into it

    I get some lovely 5k+ note with the 4-2-1 on my VTR, and it's added to the whole pop and bang effect

    Makes an immense difference in sound to MK2's with the CAT in the manifold. Can't really comment on MK1's... doubt it will make a decated car much louder.
