I've been rocking Fabspeed x-pipe paired with the factory Sport Exhaust and couldn't be happier!
Great sound and performance.

 

+1 for the Speedtech. Excellent fitment and $1,000 less than the Fabspeed.

 

My engine builder told me he's dyno'd FabSpeed's x-pipe (hi flow cats) and their claims for performance are realistic so I followed his reocommendation. He told me it was the only exhaust mod he could endorse as actually making a positive impact on performance. (Other x-pipes might do similar but the one he has dyno'd were FabSpeed) Can't WAIT for my project to be completed!

Thanks Country and Runner. For those of you that don’t know, we have our 200 cell X pipes manufactured by M&M Exhaust, GmbH. They supply Porsche Motorsports in Germany. All of that experience with POMO over the 10+ years is incorporated into the X pipe. Motorsports welding techniques are used, the material is T316 stainless and the cats are manufactured by HJS (“HF” or high flow line). Extremely high quality. Not to mention, they are listing at $ 1,471 currently. Can’t beat the quality for that price.

Here is the link to our website....

 

Twin cat for 700 less - like that savings

 

I used a Speedtech X-pipe. It is great craftsmanship and is setup for 4 o2 sensors. It included the needed hardware and some quality o2 bung plugs too in the event you don't want to run all 4 sensors.

 

And now neither can I! What is the time frame, and tell me some more about your build

 

Rock on Rhonda! Your equipment is great!

 

I just welded in High Flow cats to my stock set up... added noise was a plus... and they were a hell of a lot lighter. Not even going to attempt to say there was a HP difference

 

Looks like a great way to go
