Options for quieter exhaust?

[Linus27]

My DC5 currently has a Spoon 2-1 manifold, Spoon b-pipe and Spoon N1. For track days I swap the back box over for the OEM and it makes 94db. The thing is with the Spoon N1 fitted, it sounds lovely but it is a bit loud for everyday use, especially when cold in the mornings. On the other hand, with the OEM back box fitted, it's too quiet and I miss the noise.

Is there anything inbetween that I can use with the Spoon b-pipe and Spoon 2-1 or is getting a custom back box my only option? It would be nice to just have one back box that I can use on track and as a daily that's not stupid loud but gives some noise.

Mugen Twin loop isn't overbearing on a daily.

I'm in two minds to go back to standard, or go louder to drown out Road noises.

Could put the OEM cat / 2:1 back in, and run it as a cat back. Mines fine for a daily, yet still nice when you want it to. Would it be a noticeable drop in performance? I doubt it would. Probably is on paper though.

Spoon street backbox could be a good compromise if you can find one.

MUGEN Twinloop is a good quiet exhaust with a good note to it.

I also have one for sale in the for sale section haha

Funny, I was looking at getting a Spoon N1 & B Pipe, but I've been doing a lot of thread research and youtubing and I think it will be too loud and un-user friendly for me. I can thoroughly recommend the Kakimoto Regu exhaust that I'm running, sounds near enough oem when driving normally, mad on VTec and looks smart too. I'm pretty certain I'm going to keep mine now as it just does everthing I want at the volume I want and doesn't wake everyone up in mornings/late nights.

Love mine. Super quiet, but a nice burble. Night and day difference to my Spoon N1.

Mugen twin loop only real quiet one. I rather loose a couple bhp and not have it embarrassingly loud.

 

[Johngreen537]

I'd gladly swap the mugen for a spoon though

Love my mugen. More burble than ear ringing loud. Mine also has the b pipe silencer removed and is still a lovely noise.
Tiny bit louder on the motorway but no intrusive and i drive a lot most days on motorway and b road.

you could get a butterfly valve installed....

I can also suggest the kakimoto, has a Nice burble on startup, but is oem like when idling warm. Driving is Almost oem quiet, but when you really hit it, it makes an amazing turbolike roar that is extremely addicting

I've got a RM01a on mine as well and won't swap it for anything, drove it 704miles last weekend with no issues of it being too loud, even the Mrs didn't complain which is always a win

Kakimoto regu best exhaust looks and sound wise imo

is the Regu not restrictive though or am I imagining reading that somewhere?

It's not as restrictive as OEM, but it's not the most free flowing exhaust available.

Regu is 2.38" bore I believe? were as most go for 2.5 or 3" were possible.

I believe there's a chap that lost 12BHP (Est.) top end, when changing to a Regu from a larger bore exhaust, but this was a FI application (JRSC I believe) so there was more to be lost, with a basic N/A configuration you wouldn't lose anything near that.

At that time his car was NA Chewy.

mugen twin loop and mugen intake both people slate.. but look at the torque curve dyno result is with Tegiwa header as well... still lovely quiet tone from exhaust

My bad! I stand corrected. :xaiweb1:

That's quite a big loss for N/A then.
