Whether Exhaust For 2doors R34 Gtt Can Be Fit In A 4doors One Straight Away ?

[ryan_perth]

hey guys,

someone is selling me a exhaust which came off his 2 doors r34 gtt.

im going to fit it in my r34 seden.

but we are not sure if the exhaust for a 2doors r34 can be fit in a 4doors one straight away?

or have to do some modification?

cheers,

ryan

pretty sure they are different, the length from the cat-back will be longer in the sedan as it is located in a different spot to the coupes

If you are just swapping an end cannon with the original it will fit fine.. If you are going from the Cat ect. it will be different. Basically the end is the same everything in between is different.

R34 4door is longer, canon will sit out abit

It's not a direct fit and will need modification. Have a look at these threads, there's some pics too:

- Exhaust System Lengths On R34 Gtt Sedan?, Modifying R34 GTT Coupe or R33 GTSt system to suit?

- Installing Jjr Bellmouth Front/dump Pipe On R34, Who's done it, any advice or tips?

It's certainly doable but what exactly is required depends on the exhaust. The pipe lenghts are slightly different as well as the mid muffler location (I think). You'll probably also find that aftermarket systems don't necessarily follow the same 'path' as the stock exhaust so that'll affect things too.

I reckon a second hand system is ok to modify but I certainly wouldn't buy a brand new exhaust that'd need to be hacked up straight away to fit

thanks guys

i thought they are just a bit different in the length.. but unfortunately they are 15-20cm different....

let's say if a 4doors turbo back exhaust want to fit in a 2doors one, maybe we can just cut a bit off somewhere from the cat-back.

but im going to fit a 2doors one into my seden.. so basically im going to make the short one longer.. how can it be done? ...

you just answered your own question bro,

4door exhaust fitting onto 2door = cutting abit off.

2door exhaust fitting onto 4door = cut and weld a little bit more on. exhaust shop should be able to do all this for you

should be a piece of piss

yeah pretty much, cut where flange is, get the right length piping to cat, weld on flange back on and new piping, done. vrooom vrooom
