I have a stock B18C1 (with IAB) that comes out via a DC Sports two piece manifold, Magnaflow catalytic converter and 2.25" stainless steel hose from ebay . I removed the ebay fart can ("N1 style" muffler lol) shortly after installing the SS exhaust. Anyway, I had a muffler with a Summit chamber to replace that muffler, but it made crazy rattling noises when I accelerated hard or hit VTEC. I bought this Thrush turbo muffler as I couldn't find a stainless steel turbo muffler for a decent price…
