Those bolts look like hell

yea the welds are bad

but what the fuck is up with the routing of the exhaust
>straight down
>90 deg angle forward
>180 deg to head towards back of car

>>17075519
Must have been a Friday car

>>17075541
its like they just used whatever extra pieces of pipe they had sitting around kek

>>17075541
Pulse tuning. Pipes are an equal length from the cat. Just another example of GM excellence in engineering.

>>17075519
>New
>Slightly Rusted

fucking what

>>17075570

>pulse tuning

Does nothing unless it's a 2 stroke.

>>17075519
Not the best cosmetically, but they're properly welded nonetheless

That oxidation isn't abnormal for mild steel on things like exhausts.

It's called salt. Go to any new car lot in a salty place and look underneath. Every car or truck will have some surface rust like that. It's not a big deal. Most new cars sitting on the lot have rust coating the brake rotors. It's not a big deal.

Woow, American FCA must have some real quality issues, I have a 3y old Fiat and it doesn't come even close to that pic. Must be a lemon car.

I bet you've had lots of time to look underneath it while it's on the lift.

This is what's left of the exhaust on my car

>>17075519
>why don't the welds on this piece that 99.9% of people will never see meet my autistic standards

>>17075686
The welds are shit. Shit welds means poor performance and lots of failures

>>17075541
The pipes must be equal length before they join. Basic exhaust tuning, bro.

the more straight exhaust the better

Isn't buick just opel

way to go germans

>>17075924
Sort of, it's on the same platform as an Opel Insignia, just the Americans extended the wheelbase on it, changed the sheet metal, and redesigned the interior.

>>17075712
Bull the hell crap you say. I have dual catalytic converters, then left side (driver's side in US) has long cross over meet up with right side pipe, before going to muffler; factory. Exhaust is well tuned. The key is not GM.

>>17075519
is OP implying $37k is a lot? or that you need nice welds on a shitty family sedan exhaust?

not sure i see the problem as long as they don't leak
