Lightbulb Idea for cheap power upgrade!

Has anyone looked into if the exhaust for an H6 Outback will fit into the hangers of a regular OB?

I was at a dealership today checking out exhausts on OBs on the lot, since I have a two-outlet Stromung and want to put a hitch on. It won't clear the dual tips. Well, I was checking out an H6 single tip exhaust and that thing is burly. It is DEFINITELY bigger tubing than a regular OB...probably at least 2.5" and maybe bigger? At least as big as the 2.5" piping on my Stromung. It appears that it will bolt up in place, even with that funky add-on welded to the side of the canister.

Anyone tried this? If it works, I bet it would give a nice power increase for relatively cheap, compared to a Stromung for example.

Any thoughts? Part number?

I bet you are going to pay alot unless you can find a wrecked H6. You would be better of having one custom made to match.

Price for OEM 95-99 2.5 exhaust

Header-$179.30

CC-w/o Calif. emissions-$515.98, w/Calif. emissions-$559.48

Center Pipe-$246.23

Muffler-$219.00

Total- w/o Calif. emissions-$1,160.51

w/Calif. emissions-$1,204.01


No telling how much they want for the H6 stuff.

I can see it hurting performance, actually. From what I've read, the H6 engines use a variable flow muffler which decreases backpressure by use of a valve in the muffler. If it's mechanically actuated, then it opens by means of exhaust pressure. A 2.5L engine (or 2.2L or whatever) will put out less exhaust gas for a given rpm which might destroy any gains made by the system on the 3.0L engine (I'm not sure of this).

If the exhaust is activated by the ecu, you'll DEFINITELY have problems

Like it was pointed out, more often than not, an exhaust upgrade won't do jack if you don't have to ability to push a large amount of air thru it in the first place.
