SuperMaxx header package group purchase!


Recommended Posts

We're running a group purchase that covers all of the SuperMaxx header packages. 10 or more orders are required for discounted pricing. I can't post pricing due to the manufacturer's advertised pricing guidelines but we can provide you with a quote over the phone or if you e-mail [email protected]. Please let us know what kind of vehicle you would like a package for when you contact us.

SuperMaxx Features & Benefits

 

Heavy-wall aircraft quality stainless steel tubing throughout the system (1 3/4headers, 2 1/2x 3Y-pipe) for outstanding performance and durability.

 

Extra-thick (.375), laser-CNC-machined header flange for superior gasket sealing.

 

Factory-style O2 sensor bungs for direct fit and fully ODB-II compatible.

 

Hi-flow, stainless steel catalytic converters for increased horsepower and torque.

 

Slip-together union in the Y-pipe assembly allows for easy installation without welding.

 

Hi-flow merge-style Y-pipe for maximum exhaust flow.

 

Stainless steel Y-pipe flange retains the factory ball & socket connection.

Hey slim I was thinking the same thing. I called Tbyrne and they said that they do not have all these kits at there facility and are all ordered at the same time from the company so they are new parts and not old stock. The girl I spoke to did not know about the clearance issues with out trucks. This is certainly the kit I want but don't want the issues you had either. Lets see what we can find out!

1 slot left for free shipping! Orders can be placed online over the weekend (someone will be grabbing that spot! :) ). From there the GP will continue through Monday, March 29th. There are some very good discounts off of each header package.

 

Have a good weekend,

Tom

There are about 20 orders in for the GP so this one is doing pretty good. The last day to get in on this is Monday (3/29). Just give us a call or e-mail to add those items to your order.

 

Thanks,

Tom
