I recently have removed and sold my old Apexi Hayabusa system (B pipe & Back box). With the OE system back on, I am noticing the restrictiveness at top end RPM.
I hear the OE back box is good for 300Bhp, and looking at the OE system when it was off my car, compared to the Apexi system, the part that looked most restrictive is the B pipe, as the diameter of the OE tubing is noticeably smaller.
So, I am looking to get an aftermarket B pipe (I want to retain the OE back box for stealth and subtlety).
What B pipe has a good sized tubing diameter (hopefully simmilar to the Apexi), and also will fit straight on to my OE back box and CAT, without modification.
I dont want the Spoon, as its £££ and needs the bolt holes modifying at the CAT end. I am thinking about the SuperSprint silenced B pipe. Does anyone know if it will fit in to my system, and also what the diameter of the tubing is??
Any help much appreciated, and it would be good to hear from anyone running a simmilar system. Just for your info, the only other mod is an AEM CAI.
Cheers.
