Hey all! Obviously title says it all but as I am thinking about removing the pre cat on my '02 bertone,is there anything I should be aware of? Ie; fault codes or general running issues? Also,think my exhaust manifold might be on way out as suddenly now and then on cold start up,engine seems to be clicking/ticking and is doing it in time with engine (gets faster with revs),but seems to disappear when warmed up? Don't think its anything to do with chain as had all new chain kits fitted a couple months back. Sorry for long post but any advice or info would be great. Cheers peeps.
