Looking to do exhaust on my 2000 VW Jetta TDI. Right now ot is stock with a hallow cat. I'm looking at a 3in from a buddy for $100, or keeping the stock 2¼ and straight pipe the cat ans muffler.

I don't care about the tone, just increasing MPGs. Last months average is 59.07 MPG thanks to a .622 5th gear swap. Before that I was around 53MPG.

So far the car is: VNT17, KermaTDI tune, SouthBend Daily clutch, new vacuum lines throughout, DIY oil catch can, ventectomy, Firestone Fuel Fighter 205/65r15 tires, gutted cat and the Cascade German .622 5th gear.

Thanks yall.
