Neighbor Friendly Exhaust

[VinnAY]

I used to start my MBRP street cat back with the garage door still closed a minute or so till it idled down. Now I don't care, pretty much. It's not as if any one else in the hood isn't doing something, at some time, that bothers me. Like mowing next door at 8pm, for instance, and then weed whackering at full throttle at 9pm. Early and late noise, it's all relative in the hood.

+1 ARH Catback with H-pipe

Quite for cold starts at 5am

Muscle car growl under WOT

0 drone in 6th gear from 60-100mph on highway

This guy made a great video

Do you have this? One of ones I haven't heard in person yet.

After I moved from condo to house I have been doing this. Park backed in, start with garage door shut only open after rpms drop. Seems least impactful. I work long hours so typically means start early and home late so if i can minimize my audible disturbance then why not. And who the hell mows their lawn in the dark???

Only those that wear sunglasses at night.

Sorry, had to. I used to live in the midwest. In the summer there is plenty of light out at 9pm let alone 8pm. Further south, closer to the equator, not so much. I took a trip to Alaska once...At 3AM the sun was kind of "set" and at 5AM the sun was kind of rising. The sun never went below the horizon. Very cool trick. Winter on the other hand, forget it.

I think the way to really get rid of the cold start loudness is to either trick the PCM into thinking the coolant is warm or program it using an SCT or something to eliminate it. I'm not sure if it's coded by run-time or coolant temp, but I'm guessing the latter because I don't think the cold start routine would be needed to light off the cats if the car was recently driven//still hot.

I haven't poked around the FSM to see if the ECT sensor is a thermistor or not, but conceivably, you could wire up a potentiometer where you adjust it to 180 degrees before you start it, and then zero out the "gain" a minute or two later. This actually would be a cool little arduino project with a built in timer if I think about it.

Sorry, off topic.

Our resonated X midpipe offered through CJ Pony is a great option for a good tone without going overboard on the sound. It's quite tame with the stock axle back and opens up nicely once you get hard on the throttle.

Keep stock resonator (Helps eliminate drone) and get a nice deep sounding axle back such as this one that is fairly inexpensive and not loud at all. I live in a quiet neighborhood as well and this looks to fit the bill.

This is on my fathers day list...

I live in a typical neighborhood. Borla type S mufflers mated to the stock catback here. It's a little louder without being annoying. Glad I didn't go with anything that had less volume, or I think it would have disappointed me. Any more and I would be cringing on those 6 am startups.

A resonator delete will not give you the old school musclecar rumble that we all love, it will make the sound more raspy to some degree (that unique Coyote sound). Even with a stock exhaust you can tell a huge difference between our engine and pushrod engines.
