    Thumbs Up Decat with silencer?

    Has anyone got the above on a z20let or vxr? Getting an exhaust made up on wednesday and have been given a few options.

    I want it fairly quiet on tick over but when the turbo kicks in it can sound like an animal. Decat will definatly be too much noise for me i think but decat with silencer is £100 cheaper than sports cat.

    Any advice?

    I had a decat with a silencer and it was no sound difference to standard on idle and just a tiny bit louder on boost. Needless to say it soon came out. Youd be better going for a unsilenced decat with a small middle box in there
    It would definitely go better with an engine in it

    mines got a decat and a backbox with no mid silencer and its pretty quiet off boost and when pottering about but when you boot it its loud. Motorways unlike when it was n/a are nigh on no louder than standard. Decat also = pops, bangs and flames
    It would definitely go better with an engine in it
