Fast Intentions

Does 20 RWH convert plainly to hp? I see some places removing 15% to 20% of the RWH in final addition to HP.

Wondering if 20 * .85 + 332 = Final HP?

There are a lot of calculators just google rwhp calculator or something like that.

Drivetrain loss for manual and auto is usually different.

You can try to sell it but it might be a hassle. Someone reverting back to stock is usually who would buy but it's a hard sell.

If it's out your budget then fast intentions 12" resonated with their high flow cats.

Does anybody have any opinions on the armytrix? Seems to be really top shelf:

I've been drooling over the Amuse STTI Gold Ring but can't say I'm dissatisfied with the HKS Nismo exhaust.

all their CBE systems are TDX.

add on test pipes or a HFC variation to give you more power and sound.

FI exhausts are in my opinion the best for the Z. sound, performance, and customer service you wont get anywhere else.

Z stock exhaust is like a church mouse and does not sound good lol you're friends are lying to you or aren't car guys.

first thing I did a week after buying my Z was a call to Tony at FI and ordered my exhaust.

i put a straight pipe, no res and it sounds stock. you just get more crackle and louder. you also feel the torque better. The aftermarket exhausts kinda lessen the low RPM torque feel, while the straight mid increases it a lil bit.

SMH Worst advice I've seen on this forum.. Straight Pipe= NO Muffler or Res which in case would sound loud AF and would definitely feel power loss No Res on the other hand would be nasty and raspy in which case again bad advice

My 2 cents is get a damn exhaust or Axleback

I'm debating over FI TDX Cat Back vs the Motordyne Shockwave, the armytrix looks crazy as well.
