HEADER FEATURES • 2.0" O.D. Primary Tubes • 3.5" Collectors, equipped with O2 bungs • 3/8" thick Flanges, laser-cut, contoured for a leak free fit • One piece header tubes / No slip tubes • Under chassis design:  Above the steering center link design offers maximum header to ground clearance • Header Material:  Constructed of 16 gauge mild steel tubing.  Mandrel bent on sophisticated computer controlled bending machines for precise fit and uninterrupted exhaust flow. The mandrel bending process maintains a constant inside diameter of the tube for a smoother finish with no restriction of flow and no crimping of the tubes.   HEADER FITMENT PART NO'S & PRICING INSTALLATION INSTRUCTIONS ACCESSORIES & REPLACEMENT PARTS SPECIAL-ORDER OPTIONS:  EVAC or EGT FITTINGS

 

 

 

HEADER FITMENT • 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.  (Click here for the factory dimensions) • 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.

1.  PLATFORM:	67-76 A-BODY, 62-74 B-BODY and 70-74 E-BODY
2.  V8 ENGINES:	6.1L, 6.2L (Hellcat), 6.4L (392 Apache), 7.0L (Hellephant) 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.
3.  CYLINDER HEADS:	OEM
4.  FRONT SUSPENSION:	COILOVER without torsion bars:  The following coilover systems have been fit-checked with these headers and found there to be no clearance issues...  RMS Alterktion, Magnumforce Tubular, Magnumforce Modular Transformer, Control Freak
5.	- - -
6.  AUTO TRANS:	904, 727, GM 4L60E, 545RFE • Floor Shift:  Some applications may require the adjustable swivel & the lower rod to be re-positioned to clear the header collector.  ◊ Click here to see illustration [3703]
7.  STANDARD TRANS:	A833 4-SPEED, TKO500* 5-SPEED, TKO600* 6-SPEED, T56 TRANS • Z-bar Clutch Linkage...   67-76 A-body applications must use a hydraulic clutch.  However, DIY Z-bar clearance can be achieved by modifying the mechanical Z-bar clutch linkage.  TTi does not make a clutch linkage to satisfy this situation.   62-74 B-body & 70-74 E-body applications can use a hydraulic or mechanical Mopar clutch linkage system. *Tremec TKO-500/600:  (!) Correct installation of the Tremec Transmissions is imperative.  The output-end of the tail shaft must be in exactly the same position as the stock transmission output shaft for the headers to fit properly.
8.  FLOOR SHIFT:	YES • Auto Trans:  Some applications may require the adjustable swivel & the lower rod to be re-positioned to clear the header collector.  ◊ Click here to see illustration [3703]
9.  COLUMN SHIFT:	NO • However, column shift clearance can be achieved by modifying your shift linkage.  TTi does not make a linkage to satisfy this situation.
10.  PUSH BUTTON:	YES
11.  MANUAL STEERING:	YES
12.  POWER-STEERING:	YES
13.  AIR CONDITIONING:	YES
14.  STARTERS:	(!) STARTER MUST BE LOCATED ON THE DRIVERS-SIDE FOR THESE HEADERS TO FIT. THE FOLLOWING STARTERS HAVE BEEN FIT-CHECKED WITH THESE HEADERS AND FOUND THERE TO BE NO CLEARANCE ISSUES... • AUTO TRANS / STANDARD TRANS with a 10.5" flywheel (130-tooth ring gear)... Bouchillon Performance starter part no: 61R274 • STANDARD TRANS with an 11" flywheel (143-tooth ring gear)... Chrysler starter part no': 56029274AA RobbMc Performance starter part no: 3005 Bouchillon Performance starter part no: 61R274
