Hi guys,

Recently had a 4-2-1 and fast flow cat fitted to my car and the people who welded it accidentally left a small piece in the system which i took back and they got rid of.

However now only on acceleration there is a horrible rattle i have had the car up on the ramp with all the heat shields tightened and checked and cant pin point it. Anybody with any ideas would be great

Also got a rattle noise when just crossing 3000 rpm too that has happened ever since i have had it also never been able to pinpoint that.

F2 evolution V reg

They replaced everything up to the cat and still have the rest of the midsection and magnex back box but looks pretty deteriorated ( possibly this)? isnt there suppose to be a lifetime warranty on this?

Help would be appreciated
