[QUOTE="k3nny, post: 69338, member: 139"] Im using a Sebring Twin DTM Straight flow muffler. I bought the muffler.. no pipework. Its custom pipework.. Previously, it was just the muffler installed onto the stock pipework meaning there was 1 cat and 1 resonator there. It was very drony in the low rpm ranges but going higher up after 3500rpms or so, the engine screams like a sick puppy getting raped but the exhaust, no sound. Then i did the custom pipework, where the headers merged into 1, onwards, the pipe is now 2 and 1/4inch diameter single pipe. No more CAT, and no more stock S-flow resonator. Just a single hi-flow resonator and then my muffler. Now in the lower rev ranges, the car is very quiet.. like 1500rpm - 3500rpm, not as noisy as before, but when i go past 3500rpm, the exhaust and the car alike sounds like a totally different car from the sick puppy before.. Really like it.. but still too quiet for me. So i was contemplating removing the resonator as well and just run the pipes straight... As im heading down to the plex this weekend to try my luck on the quarter mile, i also want to make sure this doesnt cause me to lose power.. if any at all was gained la.. :) PS: im driving a 318i with a 2.0 valvetronic. My mods.. hmmm Custom cold air intake with K&N filter routed down to the M-TechII bumper next to the foglight. Above mentioned exhaust. [url]www.powerchip.com.au[/url] - tuned to 98 octane [/QUOTE]
