Is It Possible?

[Astro Bear]

Does anyone know if it possible to create a full 3 inch turbo exhaust for my r33 gts-t that will give good performance, yet still maintain the same db levels as the stock system? It is possible to incorporate the stock muffler/ exhaust tips so as to keep a stock outside appearance. I want to maintain the stock/ sleeper look/sound as much as possible. Any tips would be appreciated.

Also guys, I'm a bit confused with the components that make up a complete 3 inch turbo back stystem. Can anyone explain the parts, "dump pipe' "front pipe" etc? This is still new to me.

Thanks for your help people : ]

what mods are you planning to do to your car (what power figure do you want?)

i've heard of peeps using gtr exhasts on gtst with pretty good results (also using a decent front/dump and high flow cat ) . but to answer your question , yes you can make a large exh thats quiet , but usually it costs $$$

Ok, so the car is an R33 SII gts-t. Its completely bone stock except for an adjustable exhaust cam gear. The car is at the mechanics as we speak having a justjap stealth intercooler fitted. I then want to put an exhaust system on and up the boost to maybe 11 pounds.With a good tune, would like to get around 180-190kw or so at the wheels. Does this sound achievable?

Essentially, I like the stock look, and want to keep the car looking as stock as possible.

However, I am still a little confused as to the components of an exhaust system. Can anyone break it down for me or advise what components I should look into so as to achieve this goal?

I had a look into the Varex range of mufflers, they look the goods, but was concerned as to how performance would be affected by closing the "flap". Does anyone have any experience with this item?

under 200rwk all you'll need is a decent dump front, highflow cat and a std gtr exhaust , you could have got away with just a r34 stock cooler too

I second using an r34 side mount...no use having a front mount if you dont need it.

I also have a full 3" exhaust with an xforce rear muffler that had twin 2.5" outlets. No as loud as my previous 3" straight through but doesnt seem to be restricting power

I see no mention of engine management....

I see no mention of engine management....

This is true. Primarily becuase I know nothing about the concept. I will need some form of engine management to crack 200 kw? Please excus the ignorance, I've been driving corollas my entire life, this shit is rocket science to me!

you'll need it to hit 200 yes...

for a mild street car

cheap option - piggyback like safc

better option - greddy emanige

better again - pfc

now for the break up...

the dump pipe is what comes off the wastegate and turbo. this can be bought either in a

bell mouth: split dump:

the 2 above are a dump/front combined.

front pipe:

short dump:

and the cat:

and after that is your choice of a cannon or you can get wat u prefer, a muffler with a twin tip.

another muffler of some sort in that system could make it a quiet 3" system.

hope that helps

Have a look at a Kakimoto R cat back. Got one on my car and I love it - its got 2 oval mufflers so it's not that much louder than stock.

Gives a nice burble and i noticed a good power gain when i fitted it.

for quietness you basically want the biggest centre and rear mufflers you can get your hands on. Forget anything with a canon muffler.
