Fast Intentions exhaust is here! (continued)

dansracing · 11-28-2012, 02:14 PM

Just got notified from my installer that my FI exhaust just came in (had it shipped there) I was #608. Got it a little earlier than promised.
Cannot wait to get it installed on Friday!

if any one is questioning the low end torque i'd have to suggest checking out the dyno sheets that Tony has posted of the CBE and compare numbers.

I think it's because I'm barely pressing the gas untill at least 100-150 miles. I can't wait to floor it

You can floor it occasionally. Nothing wrong with a little cheating.

Can't wait for this thing to go on. Just can't freaking wait.

#607 delivered today. If i can find a shop open this sat I will have it installed then, otherwise it wont go on until I get back in a few weeks.

I have had the exhaust on for about a week and a half now and I think I'm really feeling the loss of low end torque. It's very sluggish in low RPMs and in fact I'm not sure if this is related or not but my car (7AT) is having trouble holding the RPMs in any gear at lower RPMs.

The RPMs for example will be around 3.5k in 4th, then if I slightly let off the throttle it just dips to 2k and under as if I was holding in a clutch on a manual car rather than gradually descend as it would or should normally. That happens in almost every gear. This is my first mod. Is what I'm feeling the loss of low end torque or maybe some other issue my car maybe having with the gears and holding low RPMs? The car is 2013 2,000 miles on it.

You should actually have an increase in low and mid tq/hp. Put it on a dyno.. another question... did you take a baseline dyno before you installed the CBE?

Yes there is. Since you're Non-Res it's not as pronounced as those with resonators. But the glass packs do "settle" as you put more miles on it, and the tone changes.

As with any mod, when you bolt it on, your ECU will compensate for the new airflows. A drop in the low end has been noticed on some occasions, and especially with the LTH's. A tune will level these airflows out and regain the losses. Also, I've noticed the problem is seen more with the 7ATs vs 6MTs.

Do most of you guys install the exhaust your self? I have a few local muffler shops here in town but i am not sure if i feel good about them working on my Z. If i had a proper lift i wouldn't mind doing it myself.

Oh yea well I like the exhaust so much I ordered another one just to have in a box.

I kid I kid. But on this second exhuast it has me wondering if I should upgrade to CF cans. I do love those shiny cans though.
