After running with a Stromung since the msprank's GB I'm thinking of going back to a stock cat-back for a change. What gaskets am I going to need?

 

Looking at Opposed Forces:

- Grimmspeed 2.5" to 3" converter with a Subaru donut (#38)

- 3" gasket for converter to OEM catback

- 2x 2.5" gasket (44011AE01A) for the mufflers

Do you have a stock DP ?

 

I have used the Grimmspeed 2X thick 3" gasket to from the Invidia DP to stock midpipe, I put a bead of red RTV on the gasket, let it tack up then install.

 

The adaptor will work too if you have a 3" dp.

305,000miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. CHECK your oil, these cars use it.
