Fast Intentions exhaust is here! (continued)

KingJoseph

I'm sorry to repeat my question, but my exhaust is just a few weeks away... does anybody have any idea how many rwhp the FI exhaust will net me over the factory Nismo exhaust? No way it's a downgrade power-wise, right? I guess it's too late anyway, but I'm surprised nobody has been able to quantify this. Come to think of it, I'm surprised I didn't do this homework beforehand.

Probably around 10-15, maybe up to 20 whp over the Nismo. (that only applies if you have a bone stock 370Z Nismo)

Honestly, it's hard to say exactly. The difference is probably very minimal. Most exhausts are going to give you a very similar power increase. You're probably talking 2 to 5 rwhp difference between the FI and the Nismo, at the most. It's most certainly not 10 to 20.

Unless you're going with forced induction at some point, your choice of exhaust should be based more on build quality and sound.

/my 2 cents

Haha, hmm... I know you've told me that before, but hard to parse out how much is the exhaust and how much is the LTHs, G3s, and tune.

I plan to do the tune eventually, but will probably keep the stock intakes w/ post-MAF tubes and drop in filters... and already have HFCs; probably won't do the LTHs. I've heard horror stories about the install.

The driver side is a PITA! Drop the exhaust from the cats back took about 45 minutes. The right side header took about 1 and a half the drop the cat and factory manifold together, and install the FI header. The left side took about 5 hrs overall. The factory heat shield is what makes it hard. Only 3 bolts hold it on. Once you get them off. You have to turn/twist the heat shield upside down to remove it. That took about 3hrs to figure it out on how to do it. Once I got that out of the way. The factory manifold and cat was out in an hour. The FI header took about an hour to install. Now if I do it again. I could cut that time by half.
