Details:

This is a stock exhaust system kit that includes: Preformed dual exhaust 2 1/4" head pipes, 2 1/4" tail pipes, Cast iron factory flanges and bolts, factory stock mufflers, muffler hangers, muffler clamps, tail pipe hangers and tail pipe clamps. This system is for All 68 GTO's, Lemans, Tempest, Dual Exhaust cars with RA or HO Exhaust manifolds.

This system is made of aluminized 14 gauge tubing so all the pipes are as thick as the originals and have a durable coating. The muffler and tail pipe hangers are specific to the particular car and exact to the factory originals. This hardware is all plated in the factory color phosphate plating with silver zinc rivets and clamp surrounds. This is concourse correct hardware. The mufflers are the correct size and shape and are made of all galvanized  materials. The seams are folded and crimped identical to a factory muffler. These are flow through mufflers that give your muscle car a rumble and are not restrictive like other stock mufflers. They sound and perform like a turbo muffler NOT a flowmaster. On the dyno the horsepower difference with the muffler and with out was 6-8 H.P.

Available Upgrades:

The stock system has 2 1/4" Head pipes that are reduced to 2" to go into the stock muffler and the upgrade system has 2 1/4" head pipes with no reduction and a 2 1/4" inlet on the muffler. This system can also be upgraded to the 2 1/2" head pipes that are reduced to 2 1/4" at the muffler for high HP engines.  The system is 2 1/4" unrestricted from front to back. This allows a bit more performance on a modified car.

Chrome tips and extension pipes - in 68 the chrome tip was an option on the car - if the chrome tip was ordered, at the factory the original tail pipe was cut off and a extension tube installed so that the tip would exit straight out the back at the bumper. The extension was held on at the hanger with a muffler clamp and the chrome extension installed at the end of this pipe. If you had a manual trans car this pipe was 2 1/4" and so was the chrome extension. If you had and automatic car you had a 2" tail pipe and 2" extension. This extension was held on by a silver zinc band clamp. At the factory to original tail pipe was cut off and the option installed. Our kit allows you to do the same.

Inline Tube is the premier reproduction brake & fuel line company and is now taking its tube manufacturing to the next level and manufacturing select preformed exhaust systems.  We have been bending tube for over 18 years and making under chassis parts that have set the bar to be the industry best.   Our state of the art computer benders and laser scanner allow us to duplicate original parts with uncompromising accuracy.

All systems are mocked up on actual factory stock cars and pre-fitted.  Our systems come in the stock size and shape of the factory originals or optioned slightly oversized. All systems are made off our exclusive computer angle exhaust bender. This information is stored in the computer so bending is exact every time. Our systems feature a galvanized factory finish complete with flat spots and factory style exhaust flanges. Our exhaust pipes install with the exact factory plated hangers so there is no drilling or generic hanger placement. Our mufflers are a factory stock appearing flow through design with low restriction so you have a slight rumble and plenty of flow.  It is the way it should be complete and correct.
