R33 Exhaust Note

[SiR_RB]

hi all

got an r33 gtst series 2, when i bought the car it came with a trust 3" to 3.5" mild steel cat-back exhaust. sounds ok but not as loud or as good sounding as other r33's...after hearing afew other skylines out n about i realised there exhausts sound so tough and awesome...mine has a trust muffler/resonator thingo about 0.5meters after the cat...could this be the culprit?

i thought it could be the stock dump and cat so i changed them to the JJR stainless bell mouth front/dump in one and xforce 3" hi-flow cat...still no change

wot is needed to hav one realy nice rb sounding exhaust note, should i get rid of the muffler and get sum 3" pipe welded in its place?

ps. its got a big trust, jasma certified cannon with 5" tip

any info would be great, cheers

just remove the resonator near the cat. all u need is 1 straight thru muffler at the end.

All I have is the front/dump pipe which is 3", high flow cat and a 3" cat back with only one muffler at the rear.

Most of the track days I have been at, I get some good feedback on how throaty mine sounds!

[SiR_RB]

when you say 1 muffler at the rear, u mean the cannon right?

ive got a muffler abit after the cat, also realised its been hit sumwhere and has abit of a dint in one of the corners with a slight hole...

hmm

one of my mates got a custom 2.5" system made up for him at an exhaust joint for $350

beats the living shit out of my straight thru 3" with xforce cannon

it has a really deep angry sound when idling and cruising, but when it gets up past about 4500rpm it sounds like it's about to tear your face off...

quite an aggressive sound really and cost considerably less than any of the brand name exhausts out there and still gave a decent power increase over the stocker

I'd get rid of that middle muffler, just put a straight pipe through and yeah, keep the rear one

yeah just a cannon at the rear, its all u need.

Likewise. I've had the oval resonator removed from my xforce system (mainly for clearance). It gave it a lot better note, but at the same time it's not at all too loud, still have the standard turbo though mind you which would contribute to that.

before i had a full exhaust turbo back decat 3" no res only a trust muffler @ end and it sounded quite as, think those trust jasma mufflers do alot.

now i got 3.5" => trust res into two 2.5" going to two 3.5" blast pipes.

now it sounds tough as but a bit to loud for daily use. almost 80% of people will turn their heads and look and 100% of police. but i still cream my pants everytime i hear it

anything that has a JASMA plaque on it will be relatively quiet (and legal)

custom front pipe out side of car sounds awesome, ridiculously loud though... not suitable for street use

i think you need to let someone else drive your car so you can hear it from the oustide, because your used to your car you cannot really hear the toughness or notice it.

This happened to me, got a few videos and then realised damn she does sound tough as!

Try it

Yeh im with GT on this one. Let someone else drive your car and just vid it or hear it drive by. Obviously someone you trust would be good!

An aftermarket manifold changes the note alot IMO.

I wasnt really happy with mine until we changed the manifold, now the note is like all the GTR drag cars you see in vids only quieter

hell yeah it does !! hugely !

[r33cruiser]

guilt toy and ntsky make a good point.

after bolting on a high mount setup, my car has more of a barble note, similar to a v8. i jsut have straight thru to a cannon

and definately get a mate to drive infront of u. u will be suprised at how good it sounds

[Bliksem]

A bigger turbo, or swapping rear housing around will also affect note
