^ oh . . so u mean those bolts which go into these bars/hangers ?
no . . in fact when i get the pipes i'll not bolt these two bars in my chassis !
cuz like i said before, exhausts are somehow supposed to be installed in flexibility so that they have space to move around when u scrap or somethin, and when u bolt them using these bars u'll have zero flexibility. plz have a look at this fella http://myg37.com/forums/intake-and-e...est-pipes.html

all pipes i have installed before, FI HFC & ART's basically have no bars like these, so they're direct bolt onto manifolds and thats more than enough, so why bother yourself with these hangers !

 

oh wow didn't realise it could get that bad

Well I went to a garage today to install the brace (As I had removed it previously) and when they installed it I realised the driver's side pipes fit fine into the provided holes but the passenger side cat needed to be moved quiet a bit (an inch or so) to get it aligned with the brace and the test pipes so I told the mechanic to leave the passenger side brace off.

So at the moment the driver's side it bolted on but not the passenger side, but for me it's reassuring having 1 connected to the brace, I understand what you mean by allowing the exhaust to flex a little if you hit it, but looking at that area I have 2 GT spec braces that will get hit first before the cats are touched.

I think i'll be leaving the driver's side brace bolted, but if I had both bolted then I wouldn't be comfortable because one side will always be under tension, and could lead to what you posted in the link above.

 

well . . it's ur decision at the end of the day, do whatever u think alright
so . . how did u see the pipes so far, any noticeable gain ?!
i know it kicks in high end, how about in low end ? did you lose some ?
cuz on the other hand my ARTs unlike these . . they do give aggressive gain in low end, but between you and me - and i'm saying that for the first time- i kindda lost some in high end and this is another reason to swap them for GTM's

 

Well I only got to drive it properly today for the first time, and so far so good...I don't feel as if Ive lost much in the low end, what I have noticed is it does perform well higher up the revs especially when shifting.

Before the pipes when I would shift between gears there always seemed to be a lag, whereas now it just keeps on going

and it is slightly louder when crusing around compared to my test pipes but they're much quieter than I expected, especially when I switched the car on in the morning.

 

aw . . thats good then

 

soo i dont know what im talking about but just throwing suggestions out, could the hangers be to weld it in nice and sturdy?

 

^ to prevent what ?!

 

good question...lol

 

guys . . this is the GTM RTP link, right ?!
http://www.gtmotorsports.com/product...cat=255&page=1
but it says for coupes only. they didn't mention that are for sedans too, is it ok ?

 

Don't see where it says it's for coupes only but they should be the right ones

 

350ZHR/370Z/G37

350z=coupe
370z=coupe
G37= could be a coupe or a sedan but i bet he meant coupes, cuz he's nowhere near to refer it to sedans from the cars he mentioned and put earlier in this category line

i hope they're the right ones anyways

 

Oh btw I'd advice calling them because the last time I ordered these they didn't get back to me until I called them and then they told me it was out of stock so you might want to check if they have them in stock

 

^ WTF . . why on earth wud they put it online then ?
they cud of put " out of stock " besides them, or make the item un-clickable or something !
this is wrong . . people should update their sites all the time.

 

These look nice with the wrapping.. What exactly does the wrapping do? Prevent some rasp and heat?

I have some rasp @ WOT but I kind of like it.. I also have that little can-buzz sound when decelerating (seems to me like almost all HFC/TP's users have this..) Does this wrap help with any of these issues?

What kind of wrap is it and did you install it yourself?




I also noticed after my RTP's were installed that the brackets that have been mentioned here aren't 100% lined up. What I mean is that the passengers vs drivers aren't 100% symmetrical. The o2 sensors are located in slightly different locations (I don't know if this is normal or not). Also I noticed that with these brackets are that the bolts that hold the bracket in place are able to slide back and forth. Meaning they can flex in different circumstances.


Take a look at what I mean: - See how the hole is pro-longed...
