downpipe on Si

ex5coupe · 05-06-2008, 01:41 AM

anyone have a dyno and or sound clip of a si with the ebay cat delete downpipe? How restrictive is the stock muffler?
anyone who has it, how does it fit and what is the clearance around the resonator to car relation.

also are the 02 sensor in the stock locations or is it moved and stretches the wires?

i got it yesterday and it fit perfectly but i have a greddy kit. The sensors fit perfectly too and they will be in the same place. Just remember to get the defouler (got mine at auto zone) and you will have to drill it or the sensor wont screw it.
