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.

POST 1 / ORIGINAL POSTEROriginal post

Hi there, looking for some quidance/suggestions for my 996 that now has a 3.8l motor built by Vision Motorsports in So Cal. I am going to use the 911 for street and track and looking for as much performance as possible but still being under 102 or lower for track time. Suggestions please?

POST 2Original post

I recently put Soul Performance Sports Cats on my 996 4s and the sound is glorious.

POST 3Original post

I have a fabspeed xpipe with 200 cell cats and the sounds is glorious but if I had to do it again I would go Soul

Didnt Vision give you a recomendation? You should contact Dwain, I sure he has a recommendation for his engines.

POST 5 / ORIGINAL POSTEROriginal post

Thanks! I was working with Steve but he didn't seem to have specific recommendations. I just sent them an email to ask Dwain. I also might have Rob at S Car Go do the exhaust as he is my local go to. thanks

POST 6Original post

I had headers, fabspeed supercup and cats. It was glorious at WOT although no idea if under the 102 limit.

POST 7Original post

Take a look at FVDs 200 cell cats and Headers, both done by M&M which builds the exhausts for Porsche racing. FVD sport mufflers would round out the sound. But I would first check with Vision on their recommendations.

Second GC�s suggestion. M&M makes outstanding products, glad to see FVD utilizing them for their exhaust components. If your engine builder gives you the green light- give their systems a look. I�ve attached an option seems like a great, Street/track combo, probably on the aggressive side. They also offer it in catted versions. https://www.fvd.net/us-en/RES9960500...m-headers.html

Are those FVD M&M equal length produced in the last couple of years or pre-M&Ms? What year did you buy them and what kind of wear and tear have they been put thru? Why sell?

​​​​Damn.​​​ Need a 3.6 set.

Not sure if I can trust their photo but it shows the same photo for the 3.4 and 3.6

POST 17Original post

I too have a 3.8. I�m currently running a Fabspeed x-pipe with 200-cell cats. The combo is good for 327 WHP! However, while getting my car tech�d before trying to go to Laguna Seca for a DE day, was told there was no way I�d pass the db meter.
