  • 1.6 THP 156 Centre Silencer Removal

    Just wondering whether anyone has replaced the centre silencer on a THP to a straight pipe, from cat to standard backbox?
    If so, have you got a video of the sound?

    Looking to make my :ds3: sound a bit more beefy without it sounding like a fart can! (dont want people to think its another Corsa B driving by!!!)

    A Mechanic from work owns a RCZ THP and he has done the same and his RCZ sounds brilliant:cool:. Only thing being, his is a 200 bhp.
    so guessing the sound would be different?

    Looking to start the mini project in a few weeks..

    Thanks!

    It will sound like the DS3 Racing [Click]
    Why? Because the Racing has no Centre Silencer :cool:
    Citroën DS³ // THP 155 // Body Ruby Red // Roof Moondust
    DS³R Speedometer // 19" OEM Cairns // KW V3 Coilovers

      Liam might have? (Dangerousfish) Not sure what he did before the car gave up, it's been awhile since I listed the mods.

      His did sound good though!

          This shouldn't jeopardise any MOT issues as it's just a resonator box. Doesn't effect emissions [emoji2] currently in the process of ordering a short exhaust pipe of eBay (no more than £20 for stainless steel) and two sleeves [emoji2]

            Well after i saw this video https://youtu.be/wMGXWtuY234 i got really pumped up and i went and did it. I payed 28 euros and the mechanic cut it out and replaced it with a normal pipe. When i first started it made wuite a nice burble, but the sound overall is underwhelming. id say it makes it like 5 % louder and it makes a deeper sound at lower revs. its got a really deep sound when you get it to about 2900-3000 rpm and release the gas. I might put a remus rear silencer in the summer (300 euros). My dream is the milltek exhaust but after i got the quote for 1200 euros for the whole dead or 600 euros for the rear silencer only i nearly had a heart attack . Well in the end id say it was worth it, but dont expect much if you do it.

              Sweet!! Have you got a video of your DS3? Would love to hear how it sounds! Hopefully if my car gets back on the road I will be able to do the same! Thinking Miltek cat back...

                I will do another video asap with the gas pedal pressed when i start it so you can hear the backfire. I dont have a go pro or something so i could record when i drive.

                      Sounds great!

                      Can't wait until I'm able to do this to my DS3. Waiting for Citroen to replace the engine first

                            Nice! Is that a full system? Resonated or non resonated?

                              Full, and the less noisy one.
