Front/dump Pipe Question

[hks33]

Hey guys,

Will be making a purchase for a front pipe and dump pipe in the next week. The exhaust system is for my RS four S stagea, interested in the Bellmouth front/dump pipe in the following link. http://justjap.com/store/product.php?productid=17316&cat=&page=2

My question is will i need the R34gtt version for my stagea considering it has the "neo" engine or will the one in the link be fine and be a direct bolt up. If anyone else has any recommendations and have used various different brands that were directly bolted up to your 25 neo feel free to share.

do your research with the search buttton.

it's not as straightforward as you think. only certain brands fit and i'm pretty sure that's not one of them.

i have got the sameone on my stagea perfect fit bolt strait up. Bolts are a hard fit on the back of the turbo because the bigger belmouth but still good.

as i said - there are mixed reports as to how well they fit - but that could be purely a reflection on the build quality of them from a start - every one might be slightly different?! grain of salt. most importantly - let us know what you decide on in the end and how it fits. it's good when people who start a thread asking a question, post the answer when they find it.

apologies i was trying to make a point to SMOKEYC34 for hasteling me on another topic.

I have a just Jap bellmouth one on my s2 rs4s

[hks33]

Those guys with a bellmouth, how did use do with the install, was it a direct fit?

[pipster11]

Yeah but I bought mine second hand so I don't have the stud to replace the bolt that can't be put ib

[horrace]

I got the bolt in but it was a mess around (you have to do it up first like a quater at a time, as you screw the others in), my JJR belmouth also rubbed the floor slightly so I gave that a slight "massage" other that that easy install. Now I done it a few times it's easy peasy.

I've got a jjr bellmouth dump. It fit perfectly except the bolt that can't be put in I snapped it off and never bothered to replace it so I didn't have that problem. Now I've got a hypergear turbo and I have to get it shortened because the turbo is longer and the exhaust doesn't fit anymore. Keep that in mind if you do a turbo swap in the future.

[RS4-S]

my 2 cents but he was asking which to use the R34GTT model or the R33 model in the JJR bellmouths, others have said they have a JJR bellmouth but not stated which one, my guess being an R33 one?

[Bronx]

ive had a jjr r33 one and it fit, then i swapped for a r34gtt, split pipe and it also fit, but the jjr was very close to the gearbox holder and rubbed at low rpm for a quick second.

all in all, both fit, and yes, the jjr has that stupid bolt you cant get in. *shakes fist vigorously*

Thanks for all the input guys need to get rid of my crappy custom made system for something a little better and higher flowing only considering the bellmouth due to the price, and with the money i have saved i can buy a nice 3" high flow cat and a 6 pack to drink during the install

[lilcrash]

Sorry didnt put what one I bought, when I got mine there was one listed for the stagea.

[KiwiRS4T]

Well I went with the split dump and never had any problems!

For the bolt that does not fit I used an allen head cap screw with the head dia reduced.

I would recomend to not get the high Flow cat from justjap it is not as highflow as u may think as i found out and buy a catco cat or metal cat a little more expencive but well worth the money I got 3 quotes before I did the dump pipe back and they all told me to put the justjap cat in the bin they are more high flow than standard but not buy much and it holds the turbo back I got a catco now big difference
