Exhaust experiment
 

Alright, the kit from Nameless Performance that supposedly makes 12whp seems like a great deal at around 1k even, but I don't like the look as much as I do the almost 900 dollar catback Greddy EVO3. I figured I could take the Greddy EVO3http://www.greddy.com/products/exhausts/evolution3/)
and pair it with downpipe w/ high flow cat(w/overpipe) from Nameless Performance:
(http://shop.namelessperformance.com/...aces-overpipe/)


Isn't there a midpipe or something that goes inbetween the two? I'm pretty sure that buying these two packages would still leave me with a stock header(of course) and a stock midpipe. I'm not sure of all the technicalities here. Any insight is appreciated because i'm new to exhaust mods.

My dad has a shop with a hydraulic car lift, so installing will be no problem.

Yes you can combine both. Both of those pieces connect to the factory exhaust so that won't be an issue. Yes, you would still have a Factory Cat ( in the header). The secondary CAT (located in the overpipe) will be replaced by Nameless high flow Cat.

Yes, you will still have a factory exhaust piece (Midpipe I believe it's called) it's between the Nameless overpipe/downpipe combo and the Axleback you will bet.

Factory midpipe is gone if you get that particular Greddy exhaust.

I'm sorry, for some reason thought it was axleback, not Catback.

Thanks for clarifying!

No problem, but I have another question now... Is "droning" pretty much a given unless I get the optional resonator, and will a resonator usually effect the openess or sound of the exhaust?

Drone is not a given, it depends on design. Pipe bends, pipe runs, size, material, etc, etc.

Resonators help a LOT with drone. Resonators do not restrict flow, so you will not loose horsepower. If loudness is a concern, (and if I were you since you plan to also do headers I would be) you should get the Helmholtz resonator they provide (Nameless). That resonator is design specifically to tone down the highest sound frequencies and minimize drone.

The Evo 3 you're interested in comes with a resonator. Or are you thinking of taking that out of the equation?

If the Evo 3 comes with a resonator, then I guess the optional resonator for the Nameless Downpipe wouldn't be necessary.:iono: Sounds like they have no effect on performance or sound(that you would want to hear), either.

Its a personal preference. Regardless of if you get Nameless resoantor or not, when you get the Header it will be loud. the question is how loud do you want it?

I personally like it as quiet as possible, but know some other people like as loud as possible or at least lets say, louder than me. So consider that, and you can safely go both ways. :thumbsup:

I think a quieter tuned exhaust would sound more attractive, so I may opt for two resonators.(Evo 3 with Nameless optional resonator)

On another note, I clicked "buy" on the EVO 3 and it comes up with another page offering more detail about the exhaust.

It says it does not include a midpipe, which means that this "catback" is just a muffler, am I right? I thought that just a muffler was an axleback, and a catback included a midpipe and muffler! I'm confused now more than ever. :bonk:

I think they may be calling the pipes differently than what we are. If its a Catback, it should replace the midpipe... :iono:

Check this post from one of the vendors selling the system - he shows on a picture where the Evo 3 bolts on to the stock system: http://www.ft86club.com/forums/showp...55&postcount=8

Well, that looks like a midpipe included to me. Where it bolts up looks like to the front pipe(aka downpipe). The Greddy website is actually just incorrect I think, because one of their pages says, "retains catalytic convertor, front pipe"-http://greddy.com/products/exhausts/evolution3/

Then the other one says, "retains catalytic convertor, front pipe and mid pipe."- http://www.shopgreddy.com/exhaust-he...3-exhaust.html

I think i'll go ahead and contact their support and ask them if it's an error.

The stock resonator reduces the exhaust/header/engine resonance. The optional resonator offered by Nameless (Helmholtz resonator) is in addition to the stock resonator that stays in place. They offer this to further reduce a resonance they find that pops up a bunch with aftermarket headers they're working on. Mixing exhaust will bring mixed results. YMMV.
