Question About Exhaust Systems

[SillyFlyFresh]

I want to buy a Exhuast system for my R33 4door non turbo

im getting some prices on a few stianless steel japanese systems

what i wanted to know if anyone has put any on there own car

and how loud is it

when i rang a few places they told me it would be to loud if i bought a HKS and other sorts of brands of exhuasts

thanks in advance

well u can buy them and get resonators put on em then they wont be loud at all! but why u want jap zorst? why not go aussie made. i guess blitz, HKS errrr a few others

Just make sure its got a good muffler

i got a dodgy 350buck job - its got 2 resinators and its so damn loud

As in it sets car alarms off in a shopping centers its so loud

[nismoman18]

hey man $350 isnt dodgy mine was $600 ($300 for CAT), i love my muffler, i wanted it loud and thats wat i got it also gives performance benefits, Setting car alarms off is fun

[Driver]

i dont mind the sound at all

but it over powers my 2 subs and yeah neighbours think im floggin it everywhere cos between 2-3000 revs is where its at its loudest.

but i dont like my neighbours anyway :burnout:

I think my muffler is called an Autotechnia or some rubbish like that

about time i got my 100th post...

mine is magnaflow 2.5inch very loud but sounds very nice has hi flow cat and resonator

i think whoever told u HKS zorsts where loud has a few things to learn, i have a HKS System and it is not very loud at all, it basically just gives the car a really nice deep note, doesnt drone, and still has all the performance benefits.

i have a 5zigen cat back, 2 3/4 inch, it could be a turbo exhaust im not sure, but its drony and loud only between 1500-2000rpm

Rest of the time its more then fine.

My car has this very distinctive exhaust note and this nice throbbing, any one else have this. Im sure its from the RB25 engine

[SillyFlyFresh]

Thanks for the replys guys

its answered all my question

where would be the best place to get a exhaust in melbourne

hey nismodified - the throbbing ur talkin about - ive got it too! sounds pretty good eh?

do you get a different, louder sound generally when cold and in lower revs? kindof a slapping, throbbing through the zorst - cause i get that for bout 5 mins every morning - neone know what that is?

[SHUTO-BOY]

magnaflow has the best value for money exhausts

i dont get that sort of noise, but i know of another Rb25DE that does have a similar noise u described

mine has a very deep note, but its hard to describe since im always inside the car when it revs thru the rev range

[nismoman18]

i love putting my hand behind my exhaust to feel it better yet i love letting ppl rev it up for me makes my heart throb with the beat haha

[Nismodified]

dont know why, but i love hearing the car hit the rev limiter cut out. i do it all the time, i think the passengers are always freaked out.

Boooarrrrrrrrrrrrrrrrrrrrrrrrrrrr-Brrr-Brrr-Brrr-Brrr-Brrr-Brrr-Brrr

[nismoman18]

yes i love it too take the cat off and flames

[Nismodified]

ive been thinking about making myself a straight thru pipe for sometime now..

within the next few weeks i have access to this computerised oxy cutters and welding gear, i should be able to cut some flanges out of 5-10mm metal plate....2.5" piping wont be hard to get,...weld me up a straight through pipe....for off road private use of course

I got a simple muffler fitted to my car for pure fx, coz i have no money, the muffler is 2.5inlet and 5" outlet, it makes a hell load of noise but in certain parts of the revs, ie: 2000-3000 main offender, it makes a shit crackling/snapping noise, i have NFI what it is but it ruins what is otherwise a really sweet sound.

i like the crackleling popping noises but thats me

it happens to me usually when i back off the throttle on decent revs.

It should be cause by unburnt fuel passing into the exhaust system.

A simply solution to get rid of the popping, if your not using 98octane fuel, then a switch to optimax, synergy or ultimate may clear up or at least reduce the noises.

i think hes talking about that tinny noise which i think is the cams/ timing every, its like a fluttering noise sort of thing, i like it
