Switching on the stereo doesn’t help, winding the windows up does nought either.  And even if you could live with it, it’s a fair bet the rozzers couldn’t.  Your shift-working neighbours may just sugar-coat you and peg out out on an ant’s nest too. 

The Evolution R-fiddled 200SX is also ridiculously noisy, but not all the time.  Keep it off the boost and it’s a gruff, blubbering bugger that gives the occasional pop on the overrun and allegedly - once you’ve removed the muffler’s baffle to liberate another 20 kW or so - spits flames between gears. 

Boost it up, meanwhile, and the noise changes to something like a tin shed full of A.D.D. kiddies banging saucepans through a 1000-Watt PA. 

That’d be okay if it wasn’t almost impossible to keep the Nissan off boost.  Sticking with a stock turbo means it spools up as swiftly as the stock 200SX but the big air-intake and $2600 worth of aftermarket intercooler mean the boost whacks the pistons back down their bores harder than a stocker can ever manage.  A monster-bore exhaust completes the package and careful tuning on the engine management has netted an equally monstrous 198 kW at the rear wheels.   Eek. 
 
While the power is certainly boosted over stock, so is the level of vibration and frizz that enters the cabin.  And, like the Honda, it’s all down to the exhaust which has so many resonant periods, there’s a new and interesting vibe every couple of hundred rpms.
