What is the stock type of extractor for B16A bigV? 4-2-1?

Anyone knows what brands are available in KL for knock-off Twin Loop mufflers other than the original Mugen. I know there is Datco for local brand. Is the quality good in terms of performance and noise level? Anyone tested it yet?
What other brands available?

Where is it located? Opposite IOI mall or is it next to the college?

What's the quality like? I don't want noisy mufflers. If possible you could PM me the price and location. If got pic even better. Thanks.

Some personal experience I want to share.

For those using DOHC VTEC B16 or any other twin cam engines (N/A), manual (assuming you havent done any heavy mods to the engine).

If you want low rpm to mid power (probably balanced power, vtec engagement can also be felt) and no noisy exhaust set up, try using 2 inches (inlet should be around 1.91-1.95 inches) exhaust pipe. You can use the cat converter or not is up to you but I recommend using it to protect the environment.

Use a center bullet (get those better ones like stainless steel). After that, use a S-Flow muffler. For the S-flow muffler any brand can be used even if it's cap ayam. Just find the one with the right inlet.
I have done this setup and all I can say is it produces only bassy sound when revved. During idle, silent and very little bass.

Perfomance wise, I get good pickup at lower rpm to mid rpm. Even during higher rpm there is no lost in power. Overall it's a balance setup for me.

This is just my personal experience and I just hope those using this setup will be happy like I did.

Haha the sound of vtec and also help destroy the environment.
