HI
Would i see any benefit from fitting something like the GT Spec 11 unequal length headers and up pipe to a MY00. The spec will be TD05FE, Hybrid frount mount, full decat, walbro pump, fse reg, K & N induction kit, Apexi PFC.
And what sort of difference would i see.
Cheers
Jt

 

imoh, they are well worth having, i would say but stand to be corrected that u would gain around 20 bhp and 20lb/ft torque. i would also recommend wrapping them, to keep them hot to allow better flow of gases. the good thing with unequal length is u keep the trademark burble.
