Should i use a 3" back box?
MY03 Remapped to 320+BHP at present, due to have another Map sometime..
By mistake i bought a H&S back box 2.5"....not realizing my Scooby had a full decat running a full 3" system...
The H&S bolted straight on, however i feel that at lower revs it pulls better, possibly due to the Back pressure of a 3" pipe going into a 2.5"
I have a Power Engineering Backbox which is a 3" but the tail is 2.5" ??
Should i be looking to sell both and get a full 3" system...Will this help with Power?
