I agree ^
Some of the welds dont look the best. Lumpy and smoove wise.
But then again looking at them in person instead of a close up picture you can see the difference.
Tho the twin pipe on yours rick does look very good!
On the loudness When i had my old celicas muffer replaced with a straight through one it took about a week or 2 before it quietened down but when i want to get a wof (Warrant of fitness) it was too loud. Maybe a resonator a two in your new system might make it a bit quieter.
I remember one of Etlsports video when he got his exhaust done i think he said his got quieter after a few weeks. ( tho i maybe wrong )
Personaly if your not happy with the welding and quality of the job id take your vx somewhere else.
I remember paying double to fit a muffler on my old car at one shop than to get the cat removed on my vx at another shop.
But yea good luck.
