A reasonably quiet back box

  1. #1
    as per title. I do a fair bit of motorway miles sat on the m4, so don't want anything too loud. Infact I just want something just a tad louder than the standard system. Why bother? Because they sound sexy, I just want one that I won't regret fitting. Plus it's a vtr not a lambo!

    Jetex is only brand I've ever used that dont give me a headache when driving. But as said magnex are also supposed to be subtle.

    I ran a raceland 4-2-1 and a saxsport system, was fine even when I went to modified nationals which was a 500 mile round trip

    ^ that is the most droney system of the lot!!
    70mph with a decat saxsport drones on and on!

    Any system with a standard cat manifold however will be quiet.
    With a decat or 4/2/1 etc any system with a middle silencer will be quiet enough.


    Though an ugly backbox, a complete toyosport system is the least droney setup ive had. It sounded very deep and smooth opposed to most of the raspy systems you can get.

    As per video text. Thats mine and its loud even with the underfloor cat. Granted the window is open but loud regardless.

    A silencer makes it super quiet. I couldnt tell from a oe bbox to a 2" supersprint with the silencer on

    I had a "scorpion imola" backbox on my vtr previously which was pretty quiet but did sound nice.. was a pretty big 3.5" tip though so depends what size you want aswell i guess.

    so if I keep it completely standard up to the backbox, it should be fairly subtle, whatever I go for? Also, I assume the smaller the diametre the quieter? Sorry for noob questions, new to modding!
