Auto Trans:

YES 

• Floor Shift:  Some applications with an auto transmission may require the adjustable swivel & the lower rod to be re-positioned to clear the header collector, see illustration sheet #3703

• Keisler Auto Trans:  Applications using the Keisler Auto Trans with the 5/8" spacer must use a PowerMaster XS Torque starter 9523.

Standard Trans:

YES

• Clutch Linkage:  OEM, Hydraulic and mechanical Mopar clutch linkage systems can be used.

• Keisler Tremec TKO-500/600 Transmission:  It is imperative that the output end of the tail shaft is in exactly the same position as the stock transmission output shaft for the headers to fit properly.

Our headers were designed to fit with the engines located to the factory specifications.  If the engine is not located correctly in the chassis, the headers will not fit properly.  We strongly suggest you check your engine location prior to installation.

Due to various manufacturing designs, aftermarket parts, engine configurations, suspension combinations, etc... TTi cannot ensure headers and exhaust systems to fit all combinations.  However, we have done our best to accommodate both factory and aftermarket component combinations.  In some cases, slight modification or repositioning may be required on your part to clear the specific situation.
