Getting the centre cat took off my 97 uk turbo tommorrow and have just wondered if this will be a problem, As i have an sti5 bb on will it be a case of the magnex straight through centre de-cat will push out too much exhaust gases for the bb to cope resulting in more back pressure or am I just being paranoid again? I know the sti bb is slightly less re-strictive than the uk twin pea shooters as its louder! and I know it not going to be as loud or as good as a magnex bb. I am changing the cat as I was told that it would make a slightly louder noise which is what I want without sounding tooooo loud even though loud sounds lovely. What do you think? please give me good news

 

will be fine bud , but i'd certainly consider an aftermarket bb in the near future

 

thats what i wanted to hear mate. Would love a magnex bb but can not afford it yet and maybe it would be too loud! we will see. Cheers for the reply.
