I generally try to produce my own content nowadays, but sometimes I find some awesome content I can’t help but to share. I’ve been following the ASM blog for years, probably ever since I got my S2k in 2008. I love how they keep updating it frequently through the years. This post about the differences between the ASM exhausts throughout the years is pretty rad. So with my shitty Japanese and google translate….. This is what I figured out + some of my own personal input.
This is the first ASM exhaust for the S2000. This came in 60mm and 70mm diameters, and made with stainless steel and Titanium. The Titanium version only came in the 70mm diameter size. According to ASM blog they went for maximum sound quality, but did not invest too much into material research, so overtime these tend to break down, specifically the the resonator. Around 2010 they did re-release refurbished versions of these exhausts with fixed resonators. Due to the reliability issues with these exhausts, ASM urged the SACLAM President Uno-san to come up with a new exhaust from Scratch…
In my personal opinion the 70mm ASM Titanium Exhaust is the best sounding exhaust ever created for the S2000. My 2nd personal favorite would probably be the AMUSE R1 TITAN EURO S SINGLE TITANIUM EXHAUST…. I got a thing for Titanium Exhausts
ASM IsDesign Silencer Kit 1
The next ASM exhaust is produced by SACLAM (quick note, SACLAM is a company started by an ex-Mugen Engineer). We all know this as the ASM Siren Exhaust, according to the blog, they achieved a more quiet exhaust, with a good flow, and a relatively straight through design. This exhaust does not use any wool packed mufflers or resonators, so overtime this exhaust does not become louder nor degrade internally as with the S-Special. Check out here for a more in depth description.
ASM ISDesign Silencer Kit 2
Due to the success of the ASM ISDesign Silencer Kit 1 (in Japan probably), aka the ASM Siren exhaust. There was a huge demand for a dual muffler version. The ASM ISDesign Silencer Kit 2 was born, designed to be paired with the ASM07 Exhaust manifold. This exhaust according to the ASM blog, was incorporated with the signature SACLAM Muffler tips whether you like it or not! (note how the SACLAM Muffler tips look and then look at a Mugen exhaust for an EF Honda Civic). This exhaust is even more durable than the Silencer Kit 1. This exhaust even comes in Titanium with a slightly different design. You can read more about this on the GoTuning website and the Ti One here.
This exhaust is actually cheaper than the previous version since they have improved the manufacturing process.
