1	Header Adapters are required if you are not running a TTI Header to a TTI Exhaust System. When ordering headers, the header make and model number will be required. • Application Note: Header Adapters by TTI were designed utilizing new unmodified Hooker, Hedman & Thorley Headers to mate with TTI exhaust systems. Precision tooling-fixtures are used to insure exact replication of each different adapter. Should your adapter not fit your header properly due to a manufacturing variation in your particular header, it will be necessary to modify the adapter to fit your particular header variation. • If TTI does not have the correct Header Adapters for your header application or if you do not know what brand of header is on your car, you will need to custom fabricate your own adapters from the headers to the H-pipe or X-pipe using our Universal Adapter Kit. Header Adapters and Universal Adapter Kits are sold separately.
2	Pipe bends vary depending on manifolds. When ordering, the manifold casting numbers off of each manifold will be required to ensure that you are supplied with the correct bend necessary for your application. Click here for a list of manifold casting numbers that TTI has exhaust pipes available for.
3	340/360 manifold casting no. 2863549 will require a 90º Remote Oil Filter Adapter. Mopar Performance P/N: P5249624
4	66-70 B-body & 70-74 E-body applications: If your vehicle is not equipped for a dual exhaust system, you will require Muffler Hanger Body Brackets to complete your installation. These brackets are mounted directly to the body panel behind the rear seat. The Muffler Hangers that are supplied with all TTI systems, support the mufflers and bolt directly to these Muffler Hanger Body Brackets, sold separately.
5	TTI Exhaust Systems were designed to use the Dynomax Super Turbo Mufflers. Using other mufflers may require modification to the muffler slips, (cutting & welding) for proper fit and alignment due to the muffler case length and width differences. • Application Note: Using mufflers longer than TTI systems were designed for will require shortening the outlet end of the H-pipe or X-pipe. Using mufflers shorter than TTI systems were designed for will require Slip-Connectors for additional length. Slip-Connectors are sold separately.
6	71-74 B-body, 70-74 E-body or 65-73 C-body applications: A modified design Torque Shaft Assembly is required if your drivers-side stock straight torque shaft rod is mounted below the torsion bar. The stock straight torque shaft rod passes directly through the space where the TTI header tubes or exhaust pipes must go. Torque Shaft Assemblies sold separately.
7	Application will fit with a Gear Vendors Overdrive
8	70-74 E-body applications equipped with a 4-speed Transmission will require a 70-72 style reverse shifter linkage rod to clear the 2.5” or 3” H-pipe or X-pipe. Reverse Shifter Linkage Rods can be purchased from Brewer’s Performance Inc. of Ludlow Falls, OH. (937) 698-4259 P/N: LR854.
9	Complete exhaust systems and exhaust component parts can be ceramic coated at an additional cost. Allow additional time for this service. Click here for ceramic coating options and pricing.
20	TTI systems must be installed from the rear to the front starting with the tailpipes and working forward towards the engine.
29	Installation of a dual Exhaust System will require modification to the transmission crossmember. A Modified Crossmember is available through TTI - P/N: 636A-CM. Instruction sheet #CMR0506 available for do-it-yourself modification.
48	Helpful hint to extend the life of your exhaust system - Exhaust system corrosion will occur if moisture (condensation) is not cleared out of the exhaust system. Make sure the vehicle is driven at least 20 to 30 minutes when ever the car is started to completely dry out all liquid/acid that is created by the combustion process in the engine. Failure to do so will cause pre-mature rotting of the exhaust, from the inside out.

b	Tailpipe Style - Turndown outlet with an angle-cut end.
c	Tailpipe Style - Corner exit with a straight outlet.
