R34 Gtr Exhaust

[TUFF_350]

Hey guys,

small favour for a good mate of mine who just purchased an R34 GTR and is looking to upgrade the exhaust. He has no interest/time in the forums (so he claims) pfft

Anyways, i made him settle for the Amuse R1 Titan catback cos it looks and sounds insane or even the Trust TI or Kakimoto Full Mega as a slightly cheaper option and also metalcat highflow.

Im a little unsure for the front section, im assuming it should be changed to keep the flow all nice and even as opposed to stock, but can anyone offer suggestions on front pipes/dump pipes? Links are not necessary but wouldnt hurt.

I used some JJR gear when i had the R33 few years back, quality was great and fitment was ok but i remember there being slight hissing sounds due to small leaks etc.

If he's using titanium cat back, would he consider titanium at the front?

[TUFF_350]

Probably not, if he does that then the whole exercise will most likely end up costing $5k.

forget titanium,

Get a full turbo back exhaust, there is f**k all to be gained in a catback on a stock front system.

Kakimoto full mega n1 whatever it is is two twin pipes that never meet and run parallel down the length of the car, probably not what you want (LOUD).

Just get a nice catback of whatever brand he likes and add the biggest highflow cat you can afford.

once you have this, find a frontpipe, there are alot of copies available now but honestly just grab a HKS one from Nengun or something for 600 or so bucks.

Yea we saw that HKS unit but were unsure if you also needed dump pipes. So im assuming no is the answer to that one? Also maybe i typed the wrong Kakimoto unit as the one we saw is single pipe not the ultra loud double system lol.

Stock dumps on 34 are fine for most applications.

Hey mate, generally most of the front pipes will bolt up-to the standard turbocharger arrangement.

You will find if it doesn't it will list this.

should you be unsure just be sure to check with the person you a purchasing it from or do a forum search.

For what it's worth, I had a HKS front pipe behind my R33 N1's it it bolted up perfectly.

You might be thinking of the Kakimoto Regu I think it is called, very nice sounding exhaust.

How far you go with the exhaust will depend basically on what turbos the car has/ will have.

If your mate will want more power in the future (he will) don't get a restrictive system, you will end up changing it down the track anyway.

As has already been stated R34 GT-R dump pipes are very good and you won't need improved ones until you add another 150kw to the standard figure (just as an arbitrary base)

I would go,

HKS front Pipe + VENOM high flow cat (google search like $230 delivered and they are about as high flow as you can get with still having the mesh inside it) + HKS HI-POWER silent.

Excellent,

thanks so much guys! The purchasing will now be so much easier

How much did it cost you to get the flanges welded onto the end of that venom cat

[TUFF_350]

Should cost around $50 - $75 at your local exhaust shop,

not a hard job so dont let them give you the reach around cos you have a GTR and "must" be loaded.

[Moodles2]

I had George @ Venom send me a pair of compatible flanges and even included a bung for my factory temp sensor for $10 extra, got a friend who does welding lined up to put them on.

[sinistaGTR]

Bought one of these today, he had some made up for skylines already. 5" body with 3" inlet and outlet

Cost was $250 del, doesnt have the exhaust temp bung installed but george included it with the cat for me to get installed.

[Moodles2]

I needed 3.5" ends, only had 3" ends in bolton form
