Front Half Upgrade Only

[Jip86]

Pw 2.1 kit, pw surge, x force 3.5" split dump with dual 2.5" system, wastegate modded/flapper, 12lb actuator, 60lb injectors. Ended up just shy of 400rwkw at 18psi.

update?

hi, finally backwith an update.

So the conclusion is, dont waste your time with a front half upgrade only! the stock cat back is no good over 300kw( yes, I know alot of people do, but they are wasting their time)

I gained 10rwkw, and 22nm of torque witht he front half. the change was slightly noticable down low, but nothing special.

Yesterday I fitted a twin 2.5, and WOW The car is a bullet, if the dump only gained 10rwkw, then I have easily gained another 20-30 rwkw ontop of that with the cat back upgrade. Totally different car to drive.

for an extra $500 its no brainer. please learn from this. They definately go hand in hand, do not persist with the stock cat back.

retune in a week or so, will keep you posted.

thanks
