Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

23 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

X-Pipe with extenders. I'm going to install this little guy tomorrow. Do I have the extenders in the right ports? I'm assuming they belong there because that's where the cats would be. The job looks pretty straight forward, any advice is welcome. Thank you. -T.J. P.S. X-Pipe is by Speedtech Performance Exhausts

Yes, I am going to. Eager to hear the difference.

POST 4Original post

This should sound very nice. Extenders look like they are in the correct place. Why do you have plugs in the primary o2 sensor bungs?

POST 5Original post

I've been looking at this same set-up. I'm very interested in your results. Are you not running both sets of O2 sensors?

POST 6 / ORIGINAL POSTEROriginal post

Quotes source post: 12680014

I just haven't taken them out yet. I will remove the plugs before I install the Pipe. Thank you for verifying the extender placement.

POST 7 / ORIGINAL POSTEROriginal post

Up date! X-pipe installed. Sounds amazing. I will post a before and after video of the exhaust note soon. Glad to have these off of the car. Dumpy old cats removed from my 996.

POST 9Original post

Speedtech makes nice products. We have installed quite a few. The X-pipes sound great on a 996. Cheers

POST 10Original post

Just curiously did you remove the headers or mufflers to get the x-pipe in?

POST 11Original post

You don't need cats in your part of the country? I also went with an x-pipe but with the cats still on it. Curious to hear what yours will sound like without the additional restriction. Also what mufflers are you using?

POST 12Original post

Mufflers and headers stay in during install. Cheers

POST 13Original post

So where's the before and after sound clips? Did you get a CEL(check engine light) after the install?

POST 15 / ORIGINAL POSTEROriginal post

Hi guys, sorry it's taken me so long to respond. Here's the problem with recording a video of just revving the engine while parked, it does the sound no justice. The sounds the car make while driving are awesome. Fast acceleration verses winding out the gears and down shifting are what you really need to hear. It's loud for one thing, I've had coworkers tell me they hear me around town. At idle it's very quiet, get the RPMs up around 4K and it howls. The sound now matches the aggressive look of the car. I'm very happy with the x-pipe and recommend it greatly. I will work something out to video the car on the road. -T.J.

And have you put them on a scale to see if there is a weight savings?

Quotes source post: 12757558

The setup is from TopGear Tuning UK. 10 lbs off the rear. Was less that half the price of Fabspeed.
