Ecr33 Front Pipes

[chilzzi]

Hi All,

recently bought a stainless stell CAT Back exhaust for my R33 GTS-t. Now looking at getting the front pipe. Being on a small budget, I came across this on ebay. At first glance it looked the goods. Ive confirmed it to be 304 grade stainless steel and 2mm thick tubing.

Any thoughts on the item / seller? Anyone purchased and installed this item? Just worried about fitment and compatibility

[chilzzi]

Why would it be annoying to have a split dump on a std turbo?

Help me out, whats a bellmouth frontpipe?

can you forward a link or something as to what you're referring to?

cheers

So many people come onto this forum and complain about boost problems etc, almost always it's because they've just fitted a split dump like pictured in that ebay link, the wastegate flap fouls on the splitter.. getting stuck open, not opening completely etc

[chilzzi]

so something like this would be better?

Link is only a front pipe, you probably want a dump+front pipe combo like: http://justjap.com/store/product.php?productid=18178&cat=276&page=1

You can make the splits work if you die grind out some of the material otherwise just go bell mouth

AS everyone has said, go bellmouth.

I had one of those, and even after grinding out the inside of the split and getting the flap to move freely, it still boost spiked.

People have got them to work, but they are an absolute PITA to get on and off. Only want to have to do it once!

hell yes, the bellmouth dump is a great budget upgrade..

Then add a 40$ turbotech boost controller for an extra 3 psi of boost and feel the difference..

30% extra power for 250$ it doesnt get much better than that

This is the CAT back i have waiting to get installed...

I know its going to be loud and it will definately drone.....the majority of driving i do is on the hwy.

whats the best solution ? from the resonator to the axle the pipe is 3.5" and from there to the muffler it steps up to 4"!!

its going to be loud.

some help please to quieten it down and no droning

thanks in advance!

Different muffler will fix it pipe size won't effect how loud it is. A good muffler will sound better then a cannon I'm my opinion

are you sure pipe size wont affect how loud it is???

its a megaphone, stepping from std manifold, to 3.5" to 4", its getting larger as it goes...

I was under the impression, that larger to smaller pipe on a turbo exhaust is a better way to go, so 4" down to 3.5 or 3" as the exhaust gasses cool it holds velocity or some such stuff... seek the exhaust size query threads for the full explanation...

[Bsa]

I ment it wouldn't effect it as much as a muffler would my bad

[SlowSkyline]

pretty simple.. add a muffler.

Im doing the same to mine atm, getting a straight through 4inch in/out oval, will hopefully bring the noise right down.. and still flow well!

[chilzzi]

the exhaust joint i was talking to are worried that there isnt enough room to install a centre muffler on the 3.5" straight run just after the resonator as pictured.....i think otherwise as the Apexi N1 Pro Cat back has this centre muffler.....

i'll get them to add a centre turbo muffler....see what they say

[chilzzi]

centre muffler as pictured on the following ebay link...

There is plenty of room. I had an exhangeable section made up for mine.

Its a HKS Hi-Power Silent, looks exactly like the JJR one you pictured. I made up a section between the cat and the flange on the cannon, for the road. Then switch it out for the HKS piece for the track/drags/lols.

Heres the HKS Vs the Trust PEII

And the section i made.

(its straighter than it looks ) I just made it with a "multi" piece of pipework so i didnt have to buy another 1.8m piece of pipe so make it perfectly straight.

Works fine, is quiet, roars up high, and still makes excellent power.
