idk, just looks like crap. ya, may sound nice. but the quality of the exhaust made isnt really a comparison to the HKS ti exhaust.

and plus, its not a true dual i dont thinl anywayz.

 

you need to educate yourself. the quality on the topseed is great.the sound is too.as far as appearance, it is only an opinion of yours.

 

OP doesn't know the meaning of rice, apparently. How can an exhaust that gave me close to 20whp (along with TP) be rice? So the HKS 'sounds' like an exhaust that doesn't get you power gain? wtf?

 

The exhaust alone gave you how much whp??? I said it SOUNDS "ricey" as in loud and raspy..That would qualify as Rice, right? Even if you got 30 whp, that's great... But I personally wouldn't get this exhaust if it sounds the same way it did on that G no matter how much so called "power" it produces...I'm meeting up with a local here in a couple days to see what it sounds like on a 07 Z..Maybe I will change my opinion then.

 

That sounds SO bad.

 

i dunno, exhaust sound is a funny thing. videos will surely throw you off on how it really sounds. i've don't have any rasp, but i used to when the engine/exhaust was cold when i would i first got it and stepped on it a bit. as for this exhaust being loud, im not sure about that, its pretty quiet compared to something like the injen. while driving, the exhaust is deep and bass-y at low rpm's then transitions to a bass-less growl at high rpm's. the only time i find it a bit loud and rumble-ly is when im in a high gear at a low rpm <1.8-2k and try to accelerate. best thing to do is find a local Z with similar mods and give it a test drive or ride in it.

 

Thanks for the input on topspeed joe645733 and Rev-em-hard. I know this is not a true dual exhaust. I don't think I really need a true dual exhaust yet. The top speed is a Y pipe and I am fine with that. Rev-em-hard did you get the 2.5 inch or 3 inch? also do you have the Y-pipe? I am thinking of getting the 3 inch exhaust and 3 inch Y-pipe to produce loud sound As far as the fitment goes, is it pretty good or way off and difficult to adjust/put on the Z?

 

Yeah, that's what I plan on doing...Hopefully it will sound better on the 07 once I get the chance to listen to it...

 

You do realize that a true dual is less than optimal on the Z33? You will at least want some sort of X or H pipe if you are N/A

 

where can i hear audio clips of these?

 

explain please.

 

You can search out the full details, but running a true dual setup is not ideal for performance. Having a crossover, H pipe, X pipe will eqaulize both banks and increase the scavenging affect, which will benficial for peformance. Not only that, but the exhaust note on a true dual is not usually that great. Look at the first and second gen injen and now the 3rd revision includes an H pipe to the setup.

 

Well its about time someone criticised the Injen Super SES Cat-Back Exhaust System. I was feeling left out.

 

im not staying n/a.

or else id prolly just get a single catback.

 

first off, the borla TD sounds pretty nice to me IMO.

and second of all, some people would rather have performance, than all show.

heres a clip of an hks setup. sounds mean to me. alot better than a topspeed exhaust too.

 

If you are going FI, you need to decide which setup you will be running and buy your exhaust accordingly. If you are looking at a TT setup, APS 2.5" or 3" or the greddy evoTT would be the exhausts I would look into

 

The injen sounds like complete @ss. I had high hopes for it, and then I heard it in person .... um.... yea, it just sounded like complete @ss, no way to sugar coat it.

I would think the newest revision of the injen would sound vastly better than the previous generations. Not only that, but the piping on the injen is beyond small. I personnally measured ID on the piping at something like 1 7/8".

The HKS definitely sounds better than the injen if anyone is wondering.

 

Free revs mean squat. show clips of flyby or in cabin under load

 

Small piping is not necessarily bad as it keeps exhaust velocity high. As long as you don't introduce an orifice-type of restriction, it is not a bad thing. Especially when you consider the cross sectional area is still greater than stock. In any case, I think davidv's 1/4 mile runs are proof enough for me that the injen is a decent system well worth the price, if you can stand the sound.
