How should i do my exhaust mod on my Supra.

[DiverSupra]

Hi,
Here in belguim they have very strict exhaust laws and no modification is allowed. Im currently running sportcat and a cuttout valve. A buddy of mine got his car impounded after the police looked under his car and saw it. So i want an oem looking straight pipe. I was able to buy a stock muffler of a totalled supra near me so i always retain my oem one just incase. I have linked what it looks like after removing the fibre glass. As seen the perforated part is not round so adding a sleeve and welding is not really possible. How would i best go about doing this? id like to close the perforated holes and leave the right side untouched so i can close my oem left valve to quiet it down or open for a near straight pipe.

Buy a catted downpipe. This way you can keep the stock exhaust in place but have the added sound and performance of the downpipe.

AA makes a great one. No check engine light, additional exhaust volume, and increased performance.

i have a catted dp. Here in europe we also have OPF Filters making the sound even quieter. It still sounds limp and quieter than my audi a3 ?

I would cut regular exhausting piping in half, long ways down the side, so you have half tubes. Then welding it over the holes.


Or if possible, cutout the perforated piping, and welding in regular non-perforated piping.

This may be a foolish question, but if you modify your exhaust to make it loud, isn't it still possible for the police to notice the volume, pull you over and still cite you and/or impound the car even if the modifications aren't visible?

FWIW, I'm in the USA and I'm really amazed at how quiet the exhaust is on this car. I've turned ASD off, and I can't hear anything.
