[urq] 3" exhaust

[Martin Pajak]

Nathan,

Yes, I agree with the details.
I need an exhaust that from the rear end looks stock (dual tips, angle cut) but uses 3" piping and one muffler only.

The fact that an S2 downpipe is longer should not matter.
Here is why.  North American cars have CATs, which probably half of the guys do not use anyway, and if they do, they will soon need replacing, or they are simply hollow.
The best thing is to use a flex pipe in place of the CAT, that way any dimentional differences can be solved there.

Hope this helps.
Martin
