Which TTI?

[71chmark]

for a 71 Challenger 440 4 speed street car? 1 3/4, 1 7/8, collecteor size ( I believe I have 3 inch on my base model hookers)? How much lead time should I expect?

for a true stock engine street car 1 3/4 will be fine , most headers are 3" collector with a reducer to 2.5"
 they shoudl have them in stock

[Aussie Challenger]

  I just got back to Australia after picking up my 70 Challenger and delivering it to the exporter in Willmington Ca. ( pic's posted soon )
 I chased up a set of TTi's for a small block and bought them from Bob Mazzolini Racing in Riverside Ca. ceramic on the outside only. His pricing was way below most others I checked on. He was a wealth of information and even since he drag races a 426 he was able to set me straight on a number of finer points for the small block. my 2 cents
