Induction Noise?

Gweedo · 18th September 2006, 06:03 PM

Hey there... I'm new to NZHondas and just bought my first Honda last week - a 1997 Teg SiR-G. It has a cold air intake and pod filter mounted down near the front bumper. It also has cheap RPS headers, standard exhaust and an RPS muffler with a 4 1/2inch tip. I took it along to an LTSA and NZPC exhaust testing day in Papakura on Sat and it measured in at 111.5db which is way to loud.

OK... my problem is: Today I had the RPS muffler replaced with an XForce twinloop. While it has quitened down (heaps) there no longer seems to be a noticeable induction noise when VTEC kicks in at 4500rpm. Does anyone have an explanation for this and is there anything I can do about it?

Cheers

I know this car, its nice as..my mates brother's car im assumming? He's also got an evo 4?. Then thats him.

You should have got a silencer, i reckon coz now its not straight thru. I think twinloops are chambered?

N1 style mufflers will give you the 4500rpm exhaust sound.

I have heard the XForce Twinloops break apart their bafflings break apart really quickly... that's just something to consider when thinking about changing it :wink:.

He has already changed it

Gweedo · 19th September 2006, 01:00 PM

Thanks guys. Yeah I bought it off a guy named Amit who also has a white Evo 4... nice guy. I heard the X-Force twinloops are cheap chinese made rubbish and the RPS headers suck too but it's a nice straight car in and out with good compression on all 4 cyclinders. I'm planning on swapping over to TRR headers, fitting a 2 1/4inch exhaust, and maybe a Remus straight through muffler because apparently they aren't too loud.

id like to see any honda on here pass the Db limits...
my car failed with 2 19" reso's and a proper rear muffler.

80db before lift off...96db after lift off...94db with a slow lift off

[QUIKdc2] · 19th September 2006, 07:38 PM

Na thats right, thats when the secondaries kick in for B18C's. But then you hear the induction sound from 5800rpm.

B18C's are more like booobaaAAAA lol

Haha yeah its phat!! Im gonna miss it when I get my Skunk2 manifold

Gweedo · 27th September 2006, 08:30 AM

True.... maybe I just need to push it harder. I'm having TRR headers and a custom stainless mandrel bent 2.5" exhaust fitted tommorow so that should open it up a bit more. Thinking maybe of changing the CAI to a short ram intake with cold airbox because it's more protected from the elements and apparently makes a louder VTEC roar.

[QUIKdc2] · 27th September 2006, 08:38 AM

Yeah you'll lose the induction noise that vtecs are known for with a 2.5" exhaust.... Mines not that noticable, I guess its just because everythings flowing alot nicer

But the Vtec at 4500 sounds pretty sweet

ITR is different to B18C, different Head different I/M etc B16a is closer to a B18CR in terms of BooBAA

i put a s/steal cat back exhaust on my b18c and yeah couldnt even feel the vtec or hear it until i swaped the ecu 4 a type r one ..went heaps better louder and holly crap heaps more top end..

lifebeginsat5800rpm · 10th October 2006, 08:02 PM

Hi there, hope im not thread jacking (sorry if i am) but i have a AEM CAI on my itr with standard headers and exhaust, and has a very loud vtec cross-over which i REALLY love. But im looking to upgrade the headers and exhaust for more power obviously. Now the 1 thing that im a wee bit worried about is that if i get a new exhaust i wont be able to hear my vtec kick in. So can anyone please help/advise me what sort of exhaust Brand/model/design/size would be suitable for my needs.
Thanks
