Side exit exhaust - road legal?

[Coremouse]

I remember from the DL theory test that car noise level is regulated, but they didn't mention emission and sorts, and we saw those old busses / pickup trucks(especially police pickup...) blasting black smoke all day long without serious consequence. Tbh, both my current car and previous car was decatted before I bought them. And renewed sticker every year without issue. 

 

Now In August my car exhaust developed some leak, while fixing her I'm inspired by an expert's build and start making a side exit exhaust, would also save some weight and ease maintenance though. I suppose if I could somehow keep the noise down it would be perfectly legal? 

 

And what if... just what if a hood exit on street? ????

 

(my inspiration, note he had two mufflers welded to manage noise, still loud though)

 

(since dont have money for big spooly boi, I welded v-band on cast iron housing to bypass royal painful 7-bolt flange)

Exhaust almost finished, start mod manifold to incorporate ext.wastegates

 

Twin scroll is such a tremendous pain to mod. First time for everything I guess...

Thanks for info. I'm in Bangkok and the project gonna be complete soon, pay tax shouldn't require the car to be present, I'll see if I could get lucky with TorRorOr certificate, will update

 

The car was de-cat'ed anyway, and the side exit had resonator/muffler on, in theory there really isn't much difference

Update: Car straight passed DLT, will be kickin for another year????

Mainly thanks to relaxing Thailand regulation(that's why I love here lol), but be fair to myself, a lot efforts went to put big muffler/resonator thingy into cramped engine bay and throughly wrapped, when car is warmed up doing slow commute, I often mistaken the engine was off. 

 

Inspector laughed when he couldn't find exhaust at rear????

 

When doing DLT also spotted several fine old cars, MB SL600(rare if real), old Rolla etc.

My car also had paper thin 8lb flywheel and slight harsh clutch, but with only ~260hp stock turbo inspector didn't have any problem. With my low salary(G25-550 = 3 month nothing) god knows when I save enough for proper build????

My ride had a "manual" auto with a 3600 rpm stall converter....A bit confusing for the test guy and closed eyes for me..????

Might I ask, as an interested petrol-head, just what kind of vehicle your engine is installed in? This front view doesn't do it justice.

Mine is a 1976, that nose/bumper was only put on that year, but the engine was changed to a earlier stronger version...The original block broke with the additional gee gee's....????

The engine is Toyota rev3 3sgte, car was FWD ST204 I believe and swapped full AWD drivetrain. I am having finance difficulty so only love I could give her now is diy-welded parts(from manifold to plumbing everything). The car still running stock power but would give her proper rebuild whence I saved enough budget
