I have a Decat system it burbles, pops, farts, bangs etc....which is nice

Now I want to keep the performance, but quieten the old girl down a bit. One of my neighbours is dying of Cancer and I always feel guilty as hell when I start up at 06:45 in the morning I must be waking her up.

I love the gains afforded by the downpipe, so that has gotta stay, the JPI backbox ROCKS so thats gotta stay to, so I was thinking, would putting the OE centre back in quieten her down some what?

If i did do that, do I risk damaging the cat when i do give it some welly?

Any thoughts?
