Ok this will be alittle confusing to explain as i am thick so i will try and word it as best as i can :p.


Ok i had a large oval backbox (Alimiumised), with cat back middle section (stainless steel). I noicted with the large oval backbox on it was pulling back slighty, so i then got a stainless steel backbox with a 3'' slash cutt inward role with this the car was fine it didnt pull back... so then i changed the middle section to a custom de cat from front pipe to backbox stainless steel with the silencer only beening the backbox :) it sounds really raspy and pops in the lower revs but when you get to higher revs it like a deep sounding noise but i dont really want the rapsy noise as much at all so i might put the large oval backbox back on will this still pull back even though i changed the system? I have also had it chipped and remapped with a bmc filter on since then.

maybe its something i will have to try and if it does then just put the other on back on.

I can't see how a backbox would make that much of a difference.

Best way to see if it changes it to fit the oval back on Rich and see how you go.

thats prob why its moving because its moving with the engine movment.you normally have some spring bolts on the bottom of the manifold that take the movment out the system.
i only just had custom de cat though so it wasnt that :) i got it all on now only silencer being the backbox all the way from the front pipe its loud what ever backbox i have on really....
