Jjr Front Pipe/ Dump + Exhaust

[Sam M]

Hey ,

I'm looking at upgrading my mostly stock exhaust system on my r34 GT-T

I wanted to go for something like jjr dump/front pipe .. catco 3" hf cat .. then maybe a custom back end.

But ive heard from some people that jjr are 'cheap shit' =/ lol . Is it really that bad? Would it be better to spend $100 more on an apexi front pipe? (i assume the dumps on a 34 are good enough anyway?) - Or would there be no real difference.

Also sound aside, would a custom system (cat back) flow aswell as an aftermarket jap bolt on ?

Cheers,

Sam

the JJR front/dump pipe is pretty decent .. its the one I have on my GTT and no issues with it. Get a highflow metal cat so you don't have to worry about melting its interior if you take it to track etc. Also a silent exhaust (catback) like the HKS Silent Hipower (91dB) should keep the cops/EPA off your back

I would just stay away from JJR splits, bellmouth front/dump is the way to go.

i have the JJR bellmouth front/dump... does the job just fine. i did hear of problems with the split type ones so i stayed away from those.

not sure about the r34, but the stock r33 dump is really quite restrictive, so i would recommend getting the front and dump replaced.

i had a JJR split dump in my R33 with their X force 3" high flow metal cat and i never had any problems with it. car ran 190rwkw for almost a year before i sold it and its still going strong with the new owner.

anywhose with my GTT im running bell mouth custom made 3" dump into highflow metal cat into custom 3" from the cat back all in stainless steal. sooooo shiny

if you can afford it go custom man.

but if your on a budget then JJR exhaust arnt that bad

nice, thanks for the info guys.

ashneel who did your custom? can most good places do it or do you need to go to a specialist in imports/skylines.

A few of you mention staying away from jjr split front pipes, what exactly is the problem with them?

Update-

Ended up buying my turbo back in parts

JJR 3" Bellmouth dump/front pipe

Catco 3" High flow Cat.

and i managed to pick up a slightly used 3"greddy PE cat back with a 5" cannon . Wanted flutes originally but i think the cannon suits the skyline more.

hopefully ill have it on within a week or 2 =]

I use a JJR intake pipe to my throttle body, sure it's cheap but it works perfectly, gave it a little bit of a blast with a sander to clean it up a little as it arrived a little rough.

apparantly boost spikes

I'm still getting one though, my R33 is only mildly worked and apparantly split pulse means it won't

have that R33 midrange lag as bad. Then again I still have factory front pipe so anything will be an

improvement

Running JJR Bellmouth Dump/Front on my 34 with Catco Hi Flow cat. Also have Kakimoto R catback.

Installed probably about a month and a half ago, no problems so far. Running 12psi with FMIC, intake, EBC and NIStune.

Works fine and good bang for back.

Also decided to stay away from split dump.
