89-92 2.5 inch downpipe/cutout

**Chunchoy14** · 12-9-06, 19:19

I have a 1988-1992 mazda mx6/ford probe turbo 2.5 inch downpipe. Comes with a 2.5 downpipe, flexpipe, and cutout. Bolt up and go. Gets the boost from stock 7.5psi to 10psi and nets a big gain from the restrictive 1 7/8 stock exhaust and cat. eliminates cat. Dynoed it at 10psi ---168whp/ 208tq from the stock 140whp/190tq. Have dynoplots to prove it.

$70 plus shipping

Can see pics at

damn...too bad I'm not sticking to stock setup...i'd paypal you yesterday

looks like a nice piece. I also like the flex after the wastegate/outlet meet.

how much shipped to 59803? And would I need a larger exhaust from this back? I would assume yes, but just making sure.

That picture doesn't look like it's ever been installed. How about a current picture.

Any reason why you made such little power on 10psi? I made 149whp/188wtq on wastegate (no boost solenoid).

This is the current picture. I took it off and cleaned the road dirt/grime and refinished it. It has been installed before. Gavin can attest to this as he has seen it in person. There would be no reason for me to lie. $70 is already a steal. The materials in itself is worth that much. A stainless steel 90 degree bend into a flexpipe to a cutout.

168whp/208tq is actually for an the overboost 9.5 setting. Did not use a boost controller, nor were there any other modifications. All stock motor. We did a test run before downpipe and after. ~140whp/190tq before and 168/208tq after we bolted in the downpipe/open cutout. I don't know what would cause your car to run 149whp/188tq at 10psi cause that is very close to stock figures.

Regarding the downpipe for sale, I have a possible local buyer. I will let everyone know if that falls through.

I'm not asking for a lower price. I just expected the picture was not the used version because it is so clean. Since you say that is the current picture, then

to it's quality.

No boost solenoid in place. I did have an EBC but it was turned off and only registered a peak of 7.8psi for those runs. Was on the stock ECU chip as well.

Definitely let me know if the sale falls through. I'm very interested. I know I could make it myself, but why bother because your price is more than fair.
