Interested in a set of Fabspeed muffler bypass pipes in good shape for my '07 997S. Did a search and found some folks interested in selling, but I can't PM them because I'm new to this forum. Please PM or email me on alex.brat@rogers.com

Couple of questions; any noticeable loss/softening of bottom end or midrange power and, if so, at what rpm range? Any noticeable top end gains and at what rpm? Were they used as a stand alone mod or with intake, chip, etc.? I plan to use them as a standalone with maybe only a K&N on the intake side (don't want to mess up warranty, etc.). Thoughts? Worth it from a power gain/weight loss perspective, for the occasional track day?

What about sound? Are they too loud for the street and/or daily driving? My 5 year old is occasionally in the back for up to 30-40 minutes; would it be too loud for a kid that age? I wouldn't be pushing it of course with him in the car, but I'm worried about drone, etc. at cruising speeds bothering him. If they are too loud, I guess I could remove them after track days, etc., but it would be a hassle.

I have a PayPal account and could pay immediately if there's a deal to be made. I would require inexpensive shipping (UPS ground? no rush...) to Toronto, Ontario, Canada and the customs paperwork would need to reflect that they are used parts of nominal value, so I don't get raped for duties/taxes up here.

Thanks in advance.

I have them on my 997s..pretty loud. I didn't like them at first cause of the loud sound/droning etc but I got used to it and they sound pretty good.

 

Any noticeable change in power characterisitics, up or down? Is the power/sound change worth putting up with the extra drone/noise?

 

A little increase in power IMO, the rest of the questions you ask are really just opinions. I think its worth it..its only like a $300 investment so if you don't like it you can just sell it

 

You've got mail.

 

I have a set for sale used for less than 700 miles.

 

You can make your own for less than $30. It's basically just a bent pipe.

 

Interested, but can't PM you cause I'm new and I don't have 15 posts yet, which is the minimum required before I can PM anyone on this forum. Please email me on alex.brat@rogers.com and I'll reply via email. Thanks.

 

Anyone know what diameter they are?

 

I think they are too loud for small children riding in the back seat. I don't have any kids, but if I did, I wouldn't subject them to kind of possible hearing damage...
I drive mine daily and for me it sounds like how every 911 should....
