advice on replacement back box

[alexb]

Hi guys

The back box on my import FD is on the way out, so I\'m looking into getting a nice shiny replacement. Thing is, I\'d like to get a more fruity exhaust note but not go too loud - my old scooby with an Afterburner was deafening - I\'d like to still be able to hear the stereo in my rex

So, does anyone have any suggestions on a good one to go for? I assume the jap-spec ECU will be ok with this mod too?

Cheers,
Alex

Alex you best option would be to get yourself something like an HKS or Apexi box. That way you could always put the bung in the back for those days of silence.

Cheers Dan, didn\'t think of that!

Can anyone clarify the differences between the HKS models? I\'ve never been sure!

Thanks,
Alex

Avoid HKS if you can, I think a couple of guy on here were not impressed with the quality of them.
Blitz, Apexi have good names for an exaust.

Some people have found that some of the HKS systems rust on the weld joints.  I found this on my dragger version i had on my MR2.  I had the blitz on my old RX7.  Sounded cool....but was loud, especially with the cat ditched but build quality was excellent.  I like the Apexi units but these cost a bit more than the blitz ones.

Oh....if you are wanting an exhaust let me know which one as i may me able to get it a little cheaper

Best thing to do is see and hear as many exhausts as you can. My experience is that:

a) HKS cans fall apart so I wouldnt have another

b) the Apexi cans are built really good, though some can be loud.

c) Blitz cans seem well built but the Nurspec is loud too

d) Feed sound good (nice burble rather than noise) and are built really good

Largely down to personal preference i.e. 95% about how loud you want!

How do u know what sort u have - i.e is it written somewhere - sorry for the highjack!

[alexb]

Cheers for all the advice guys! I\'d almost decided on a NUR Spec, cos I think you can get a bung for them... Feed sounds interesting though, I\'ll have to check them out too

Adam, cheers for the info, I\'ll let you know when I come to a decision!

Thanks,
Alex

blitz is the daddy IMO both on quality & noise/sound. Unless it\'s different on different models thou only the blitz Nurspec type R, ie centre & backbox, comes with the bung. Luved it on me scoob thou & praise the bung else big eared neighbours wood of had me lynched lol

i have a kakimoto which seems quite good, quite loud though

[alexb]

Cheers Si, wasn\'t sure of the bung situation re: the Blitz stuff:)  

Anyone know who sells FEED stuff or what their website is? Done a bit of looking around and havn\'t come up with anything

Saw some Racing Beat kit on a US site that looks pretty nice, dunno if it can be bought over here though...

[Gman]

Mine is very large and sounds awesome - also has a bung, i would tell u what it is but i\'m not sure myself!

What do you want from the exhaust sound- and performance- wise?

These 2 factors will dictate to some degree what you choose from. If you are intending to maintain a \'standard\' car i.e. stock twin turbos, I dont really think it matters that much, depending on what exhaust mods u have already of course.

If you are going single turbo at some point and will consequently be able to rely on a big external wastegate to control boost adequately then you may as well get as best a flowing system as you can. IMO this means either Apexi N1 or GT-spec or one of the Feed items (forget which) as these are built largely from mandrel bent 80mm pipe, there arent many others who can say this. I think the GT-spec was the only 80mm system for a while in fact. Having run an Apexi N1 and 2 HKS Super Dragers (in the brief time before they both rotted out!) back to back the difference is huge; the HKS flows nothing like the gas the Apexi system does...

I imagine the other real rotary outfits e.g. RE-A, R-Magic, Knightsports etc also build excellent systems (no personal experience of these though, yet!) and you can hopefully be assured that they are built to a standard that will last on a turbo rotary, unlike HKS systems!!

The Feed exhaust is called a Feed Sonic SR, only a few around though (me & Phil G I think), but they are good!

ReWorx got hold of them for us, so should be able to get some more if there is demand, likewise I am sure they can get Apexi units.

Thanks for your input guys!

I\'m not really planning on modding the car that much, I did a few mods to my old scooby which was fun but ultimately too expensive to be worth it

So, as much as I\'d love a ported, single turbo 450 bhp monster, probably I\'ll just stick with air filter, exhaust etc to give a modest increase in power without breaking the bank!

Max, cheers for the FEED lead I\'ll give ReWorx a call!

Oh, gman, no spoiler is deffo the way to go! I always thought the type r spoiler looked a bit \'stuck on\' (which it obviously is, but you know what I mean!)

Cheers,
Alex
