chris

 

Blitz nur spec r IMHO

 

Probably the loudest is Blitz Nur Spec or the Twister

 

or mine

 

the one i have now is the loudest ihave owned, a blitz nur spec R with de cat

I have had previously a scorpion, mongoose and scoobysport. the scorpion comes close.

 

can u get a blitz decat pipe for the downpipe ???

 

Dunno if u can get a blitz downpipe, ive kept the scoobysport downpipe on mine, it fits

 

I thought the loudest was the Buddy Club exhaust ?

 

My exhaust is straight through light weight titanium, made for JDRA (Japanese Drag Racing Association), and it's louder than Blitz, or any other Scoobies I've heard Haven't measured the db, so can't be definite, though.

 

Buddy Club without a doubt. If you don't believe me speak to BL as his is outrageous!!!!

Saying that the loudness of my girlfriends scoob with the engine build & a Hayward & Scott Aftyerburner is a real neighbour annoyer LOL Got in mine with a full Scoobymania after driving hers & it sounded like I was driving a Rolls Royce or something equally as quiet LOL

I had a buddyclub on mine, you cant belive how loud this exhasut is without hearing it on the flesh, heard a lot of exhasut now and this one is another level. Was a nice loud at idle but going through the revs it sounded like a spitfire, and going up a hill was embarassing, took it off the car the day after.

 

Mine i think Chilledbudweiser will vouch for me lol

 

YOU WOOOOOOOOOOOOOOOOOT?

Oh lordy driving behind John, and all of a sudden the british army lock and load a wepon of mass destruction, so of course I duck for cover.

Turned out to be Johns exhaust popping and flaming in front of me

That exhasut isnt rude loud, but damn cool loud.

 

Mine

Fujamitsu from downpipe back then a custom downpipe

When its on the drive it shakes the house on tickover

 

lol, whats the decibel rating matey??

Mine was tested at 115 on tickover

 

i think its got to be the buddy club, well loud.

Quote from a race bike website

Thats a 'Race Can' - basically no baffles - just a straight through pipe....
And yours is louder than that on tickover??? wow

 

The standard way to test the noise is with a meter at 45 deg angle @ 2m distance @ 3/4 revs. My loudest is 104dB (race car engine) - which is rather loud so 115dB at tickover - not sure thats possible unless you are running straight headers.

 

Nothing like converting it back to standard minus the cat/s though.

What a hoot accelerating passed vehicles and having a blast on your own without bringing birds out of the sky and attracting unwanted attention a mile before arriving anywhere.

Stealth is the new noise.

 

Have to agree with Spoon.
Since i went to equal headers, i then changed to an H&S system and BB, it's real quiet...bliss compared to my Nur Spec R that was on before !

 

My de-cat system is part Magnex, Part Miltek and although its not very loud its cruising drone can be quite intrusive. How do you guys cope with Nur Spec etc? I'd love a loud exhuast to upset the neighbours (can't stand the lot of them!) but don't want to deffen the nipper.

 

Blitz Nur Spec R with Scoobysport downpipe was roughly recorded at 118db - pure mental.

HKS full decat and Firestorm was 103 and 112db (cant remember which one which).

Buddy Club is *supposed* to be the loudest. However, went to Bl's and i have full blitz and he had Buddyclub and he was pretty shocked that Buddy Club wasnt as loud as its meant to be. Couldnt tell which was the loudest but lets say he wanted to see his Buddy Club and get another exhaust. lol

 

I got 116db from a recently calibrated SPL meter at the Xtreme Scoobies Rolling road day, 99 UK Turbo with a full decat and a firestorm, that was peak.

I'm not quite sure how you can get 115db on idle to be honest.

 

I thought the Blitz was very loud. I seem to be used to it now, but for the first few minutes I was considering on changing back to the full scoobysport. That all changed when i got home, 3 car alarms set off in 2 miles

Never heard of a buddy exhaust, sounds a bit poofy

 

115 wasnt measured at 45 degrees, was straight next to the pipe.

 

I can only tell you that my Blitz Nur spec and full decat is `kin louder than most i`ve heard. even louder on a warm day for some reason.

 

Watching the power engineering vids in the southern section it was bloody loud cliff

 

lets hear these zorsts in action! :P

 

At Prosport mine hit 127dB at 4m and then the SPL meter broke. This was before the revs peaked!

It is a custom straight through system. It is fairly noisy!

 

Rannoch. Do you think there will be a db reader at the Scooby Shoot Out as i'd love to know what ours is putting out as it's silly loud? LOL
