2002 Forester S

Default Installing Cat Back Exhaust on High Mileage Forester

I've been away from Subarus and NASIOC for several years. I have worked in sales now where I've been provided a company car at no cost.

I picked up a 152,000 mile 2002 Forester S yesterday that is in great shape with no sign of head gasket issues and it was well taken care of. I need it primarily as a hunting/light off road vehicle.

I don't want to mess with the stock air intake system, especially after finding no gains from intakes in the past, especially in the low rpm band. I do want to do a cat back exhaust system for the Forester. Stromung makes an excellent product that I had on my 1998 Legacy GT.

Will a cat back exhaust upgrade have any detrimental effect on a high mileage vehicle? I don't want to do headers at this time, simply a cat back for the sweet resonance of the boxer engine.

You will not get the true subie rumble out of a naturally aspirated engine without swapping to unequal length headers. Good news is you can get the knock offs for cheap. Also, there are a few companies that make cat back systems them to work on the foresters

The catback will not have any effect on a high mileage vehicle... in fact, your old exhaust is probably getting old now and a new one would be good for it.

I'd highly suggest a Ganzflow style intake. They actually work. I do believe they should work with your year forester as long as it's MAP. I just bought one for my dad and his the other day!
