Stebro test pipes

Only thing I've heard as far as the install is that you should probably go ahead and put on new hardware and gaskets while you're in there. I bought the gaskets and they were only $2.33 for both. Hardware wouldn't be any more than $10.

Post a video when you're done!

Yes, I'm using the bypass pipes with my stock S muffler. I'm hoping to make it sound a bit sportier, without having to replace the muffer with a PSE or an aftermarket one.

I already bought a pair of gaskets ($3) and I'll see if I can reuse the factory clamps or not.

The factory clamps are pretty beefy. I've had mine apart at least half a dozen times with no issues. I've also reused the gasket between the header and the bypass with no issues.

I just finished up installing the pipes. Yes - the factory clamp connectors are very beefy and there was no problems in reusing them.

The test pipes install was pretty simple, they fit perfectly, and I was able to get everything done in about 1-1/2 hours, taking my time.

Here's a photo of the secondary cats and the test pipes side by side.

It's pouring down rain here in Seattle, so I didn't take the car out for a drive. I just started it up with the garage door open and it does seem to be a bit sportier sounding. (It has a stock S muffler on it).

Hopefully it will clear up here tomorrow so I can see how it REALLY sounds at higher revs on the open road.

Unfortunately, those are not mandrel bent. Also, as others have commented, that looks to be cheap aluminized steel- the same stuff you get from Midas. As much as we all know the FabSpeed stuff is expensive, it is well made, is stainless, and their bypass pipes are indeed mandrel bent.
