hi, just need a bit of insight from people in the know really i.e u peeps on here.
right ive had my car ( 1.8 z18xe i think) played with a little bit an could do with some advice.
its had a diblias air intake, diblias sports manifold, lexmaul four branch (whatever that is) and a 200 cell sports cat.
now my problem is its quite noisey as in really annoyin while in the car noisey!!! so took it to a garage to see how much a stadard cat would be, tried charging me 350 quid which personally i thought was a bit steep but thats prob me being cheep lol any way i found out its not a full stainless system ive got on there so think i want one now, but my question really being is, would a stainless system be better for me if i got a standard cat would it strangle any power or slow me down any??? i want a new back box but with it being a sleeve fitment its going to have to be back box and centre section isnt it???
sorry if this doesnt really make sense i just need a helping hand.
