Custom Short Tails for Fast Intentions Exhaust
 

Hey guys -


So my set-up is/was all Fast Intentions. i've been running FI non-res test pipes, with a FI non-res CBE, and the carbon fiber mufflers. this set up is loud and for most people a bit too much. not me though. i've been running this set-up since around september 2011 and i've loved it from day 1. FI makes the best exhaust hands down and their customer service is second to none........but we all already knew that :tup:


butttttttttt i wanted to know what a fully straight piped Z would sound like and how much louder it could be than just 2 little CF mufflers :stirthepot:


So in closing I do believe I now have the first and only short tails made to fit the fast intentions cbe exhaust :tup:



Build:

first thing i did was put in a call to Tony at FI. i searched for a set of tips for hours and nothing caught my eye or looked as good as the FI tips that were on my car. luckily Tony agreed to sell me a set of extra tips for this project. next i had a friend of mine, who custom builds drag racing exhausts, order me whatever pipe he needed to make this happen. sadly first shippment the place sent the wrong steel. they sent us regular steel rather than the stainless we had ordered. got new steel overnighted. he did the exhaust out of all new stainless with mandrel bends. i had him mimic the shape/bend of the rear FI sections i was removing and also same hanger locations. his work came out awesome. minimal welds and tip placement was spot on.


Sound:

when i got to my friends shop he had just finished my exhaust (and diff fluid change since it was already on the rack :tup:). temp yesterday was only about 27 degrees so it was a very "cold start" lol upon hittin the start button my jaw dropped. this was the most violent and raw (awesome) sounding cold start ever lol it was way more than i would have ever expected. once it warmed up a bit and the revs dropped to normal idle i was kinda surprised that at idle it sounded about the same volume wise as my regular set-up. after it warmed up a bit i took it on a short test run while going back to my house. 0-2900 RPMs it sounds about the same as my old set up but when you hit 3K RPMs+ its a whole different animal. i've never heard anything like this on a Z. i will admit this may be too much for how i daily drive this and my neighbors hated me plenty already WITH mufflers :bowrofl: this however was the exact reason why i made these to be completely interchangable with my FI mufflers. 6 bolts and its changed. no hacking up Tony's beautiful exhaust and mufflers here. hence my purchase of a extra set of tips so i have 2 sets of rear sections now. :tiphat:


Performance:

4/7/14 update:

had some time behind the wheel lately with some warmer weather. sadly it's been not too warm and a bunch of rain. throw in some semi-bald rear tires and it's been hard to actually get on the throttle hard without massive wheel spin.

inital report is that i'm unsure if i'm babying it in low RPMs due to wheel spin and the just epic roar once 3k RPMs is cracked OR if i may have some TQ loss. i dont feel that i've freed up too much back pressure to create TQ loss so i think i'd have to go with i'm just being soft on the gas initially.

on the other side of this, whenever i'm WOT the sound is simply amazing and brutal but in a good way. it feels like i gained a few top end HP actually whne doing higher speed runs.

i'm working on getting on a dyno run set up soon to see whats up.

In for video/audio clip.

I tired to on my phone but doesn't really capture sound as good as I want. Maybe going to snag my sisters go pro since she is coming home from school this weekend.

Any tips on best ways to capture exhaust sounds clearly?

You need to get the external mic for a GoPro - the GoPro itself has shitty sound.

Put the mic just above the exhaust on the bumper (or plate to keep it off of your paint?) and then do some nice acceleration. :tup:

Welp amazon overnight maybe lol

Also are those pics too big? I'm on my phone so I can't tell. I added them as the "best" option. If they are too big I can edit and use the next size down.

Nah, not for me. There's no horizontal scrolling if that's what you're wanting to avoid.

Precisely lol thanks!

In for good sound clip! :tup:

*Pics are perfect size for me

I'm looking for gopro external mics now to get here by Friday. Hopefully ill have some video to upload after the weekend if the weather cooperates.

not bad on looks, would be interested in sound as well being non-resonated i suspect it to be a bit on the loud side

It's very loud lol I'm not even sure if any mic/camera I use will truly capture what level it's at. We shall see.

I can't hear anything :mad:

:icon17: Nicely done :tup:
