Spluttering exhaust..

Fitted a new non resonated cat back miltek exhaust sounds lovely, but when i accelarate at 2500Rpm it kind of splutters for a few seconds then will pick up again... its very noticable

any ideas??
 
Havent got permission to see that :worried: but yeah flat spot at 2.5k :/

It would cost you £5 to become a paid member and find out how many seem to have fixed it for just a few pence and chances are you have the bit required sat in your garage :wink:
