You may want to consider Tasca as you are close to their location. Dunno about Volvo OEM.
I bought a cat back from iPD in 2010 as a kit for a 1991 240. Starla (big pieces and piping) and Walker and Bosal parts. Fits like socks on a rooster. The aftermarket rubber hangars deteriorated in under two years.
I've not yet grounded the exhaust to the chassis like at the tail pipe hangar. Grounding the exhaust to the chassis greatly slows corrosion. Use braided stainless. The tinned braided copper conductor is not so durable to the turbulence and heat under the car. A poorly grounded exhaust system can limit O2 sensor effectiveness and corrode prematurely (faster in salty and frozen places).
Be certain the head pipe in put flange is well secured at the exhaust manifold output flange. The three retainer nuts can loosen overtime shortening the exhaust gasket duty cycle. You may want to closely inspect the four gaskets between the cylinder head exhaust output and the exhaust manifold input. If they appear rusty and flaky, the four gaskets may require replacement sometime soon. I have to replace mine.
Be certain the hangar assembly securing the center the head pipe to two lower right bell housing bolts is secure. This connection is also a good ground point for 02 sensor operation. On one car, the upper plate with embedded nut fastener was gone, having rusted off. I had a spare bracket that would secure to the now missing nut in that plate. A discount muffler place welded the bracket bottom to the head pipe and secure it, using the two screw and single plate assembly, to the bracket secure to the two bell housing bolts. The head pipe is old yet sound. Use anti-seize compound. Molybdenum-based anti-seize compound may be better than lead-based.
Finally, you'll also want to be very certain the flanged connection between the head pipe output to the catalytic converter input is solid and does not leak. This exhaust connection is very critical and should be checked on occasion. Or have it all welded together, yet supported.
Maybe check 02 sensor and inspect the catalytic converter?
I found a catalytic converter-back section as won welded job in the yunkyard a few months ago. So, for 20$ for this catback section and one hour's labor labor welding. I brought extra Volvo rubber hangars since the after market ones deteriorate so quickly. Exhausts sounds like it should. Welding is cool.
Hope that helps.
cheers,
dud.
