Just got my new center section pipe from GMG all pumped to install tonight for track weekend!!! BUT no exhaust clamps sent with it... said they were on back order will ship out asap!!!!!!!!!

oh well we will wait!

That doesn't seem like good customer service to me. I would be pissed. It's like ordering a 60" plasma in time for the Super Bowl and not having the power cord.

maybe you can use the oem clamps. pipes should be the same size as oem.

930man

thats what i am thinking ... but they said they were different stainless steel clamps ...

doc2s

must be painful to wait for the clamp.

No clamps but I'm sure you got charged already. If so, charge 'em back for incomplete shipment and see how they like that?

Mine initially came without the clamps too... hang on, it will sound great!

if you are changing just the center section, the stock clamps have to fit...they just will not be as shiney....shim/sleeve them if you have to to account for any diameter differences.

leif will be trying it today!!!!!!!

Here is a pic. Maybe you can cut one of these out of the pic and use it. Just kidding. That really stinks. Hang in there...you will love it.

Guys, I posted this on the other thread and don't want to hijack but since you're installing these make sure you swap out the stock header bolts for some 997tt stainless steel ones. I'm working at getting some of those on every kit we send out with ours if I can. You have to remove the cats/headers to be able to install both ours and GMGs (or any center section) so it's well worth the few bucks...

NSXTC

Seriously? Just to swap out ONLY the center muffler, you have to remove the cats/headers?

Do you have the part # for the TT header bolts? I would put anti-seize as well then.

Thanks Alex.


**Edit** Looks like they are M8x26 (18 needed; torque to 17ft-lb or 23Nm). The diagram below shows the torque sequence for the header bolts. The GT3 headers have 9 bolts per side vs. the 997s as shown below. Just torque from center header outwards.

i didnt remove headers for mine just loosened the cat clamps slid righ in ....
but ss bolts for headers good idea

GT3CAR

Same with me. I did not remove the cats or headers
