Best place for an exhaust system

[snake]

Got the exhaust done at AAA, did a great job, thanks Busky2k for the advice. Just gotta love that RB roar dont ya.

PROFIX????? hehhehehe

[Busky2k]

Got it done at AAA eh? Good stuff!!

Tell us what you got done, what you thought of it.. hehe Im suprised you paid 1400 tho. I guess they probably realised by now they were underselling themselves compared to the competition!

I'm glad u didn't go D&T.

I was horrified when I pulled the dump pipe off. Where the 3" S/Steel is stretched over the flange the bottom of it didn't quite get stretched enough. This caused A V raise in front of the compressor wheel. Not to mention all of the welding slags spots that were splattered everywhere inside the dump pipe. The final weld on to the flange was really rough i.e not diegrinded. For $1700 that I paid (slightly different muffler to the $1650 price) I expected a 100% professional job. Not rough slap it together job. Also bits were painted on the exhaust which flaked off after the first wash/rain and the welds are now starting to rust. When looking at the back of the car you can see the flat bit of the large rear muffler. The black paint there flaked off in the first week and looks daggy. Also when removing the dump pipe the bolts had been rounded off and not sitting flush up against the flange as the weld slags was holding the bolt from sitting flush.

The note and sound of the exhaust is nice though.

Im surpised D&T did such a bad job. I thought they would have used an 'off the shelf' dump/front pipe kit because its much easier and better. Looks like D&T isnt the place to go to then. They look more like a V8 place anyway...

I had the exhaust place across the road check it out and they said they diegrind the weld inside of the dump pipe so its nice and smooth. I think the place across the road from D&T is called Exhaust Techniques or something. They wanted $350 to fix up the dump pipe. I didn't bother as the RB30E is 30mm or so higher than the RB20 so I am going to have to get another dump pipe fabricated.

Also D&T made the dump pipe/front pipe as a single piece which was a real pain in the arse when removing it. Well compared to having a flange that seperates the front and dump pipe.

I'm not sure if the V infront of the exhaust wheel is causing extra lag or not as I make around 1-1.1 bar of boost at 3500rpm.

If it wasn't for the shitty paint and messy dump pipe I would have been very happy with the job.

Extremely happy with AAA, Gordon down there knew his stuff, showed me the ressy and muffler that he was going to use and a dump pipe that he had made for another customer just so i could see what the final job was going to look like. Ive got the supercat cannon muffler hanging out the back and he tilted it in such a way so that the muffler has enough ground clearance but still sticks out at an angle like the jap systems do, he explained all this to me which was much more than what D&Tand ET did. D&T offered me a free dyno run before and after but i was cautious of this as when they did the exhaust on my ET pulsar they told me they would do the same but then didnt and made up the excuse that my radiator was leaking and they didnt want to risk it, could have told me when they found the leak untill waiting until i handed over the money.

Just fitted a HKS super dragger - much better than the Nismo one I had - up top anyways.

Does anyone know if the super dragger is above legal noise limits? Hope not, cos it has a really nice bark.

Im currently lookin to get another muffler put in my exhaust cos its just too loud!! Ill try AAA cos i just want somethin that quieten it down and doesnt change the tone too much.

[Steve]

What sort of exhaust do you have? Have you thought of an Apexi flap thingo? Really takes the edge off.

[EnricoPalazzo]

meh not interested in that. Just wanna quiet it down. Its farkin loud at idle and causes too much attention. Ill checkout the flap thingy. I tried makin one last week but didnt work how i wanted it to and was too restricive. Cyas

[Steve]

Thats the big problem, noise is reduced by increasing back pressure - a quiet exhaust is a restrictive exhaust.

Thats the good thing about the apexi flap, 1/2 a second to open it or shut it. So when you are just cruising, you dont get added attention.

What exhaust do you have?

[EnricoPalazzo]

a big one.... (read i dont know, no brand name except trust front pipe)

[EnricoPalazzo]

just got a resi put in my exhaust. Did absolutely nothin

What to do.

[Steve]

Eat the wagonwheel, eat the wagon wheel!

Err, sorry, I meant, get an Apex flap:) If you go down to D1, James and Rob both have them fitted so you can hear how much difference they make.

[Busky2k]

Did you get a proper mid muffler installed or a resonator?

I told you resonators dont do shit!!!!!!!! =P

[EnricoPalazzo]

im goin for a mid muffler now.

Steve how much are the flaps...

[Steve]

Not sure exactly, maybe around $350?

[whatsisname]

Guys I beg to differ re resonators!

The Trust system on my car has a resonator (offset design) that I recently had flanged for easy install & removal. Bloody hell did it make a difference! With the straight through pipe exhaust note is deeper (very tuff sounding ) & it certainly is louder. Thankfully it's not annoyingly loud due to the design of the Trust muffler.

I'd go as far as to say I'm 99.9% sure there's an few extra rwkw to be had with the resi out.

With the resonator in - exhaust is very quiet until you go WOT (just what you need for cruising). In fact the turbo/induction noise is faaar louder.

With the resonator removed - extra exhaust noise/deeper note is noticeable even at idle.

[Steve]

What do you mean by offset design? Does that mean its not straight through?
