My '97 b4 wagon's catalytic converter and center muffler have shed their heat-shields and are getting pretty rusty. The whole exhaust system sounds like its starting to leak so I may have to start replacing parts. I'd like to plan a mild upgrade to increase power and maybe gas mileage for street use only.
I've seen the Techtonics Tunings 252.417 2.5 in. stainless cat-back system containing 2 Borla mufflers and pipes in between for around $535.
In case I need to replace it too, I've looked for catalytic converters but don't see any specs so I can't compare any offerings against OEM.
Can anyone either tell me some of the aftermarket options for exhaust system replacement (other than OEM)? Or link me to a thread or website that does?
Thanks in advance.
