I am looking on purchasing headers for my 89 vette 6 speed. I want to know whats the best to use with my stock gears of 3.45 and all the other mods i listed.
p.s. I will also be considering a new catback system any opinions on which one to go with will be appreciated. I ride my vette on the street mostly but will race occasionally.

If the engine is under 400 cid, you will be best served by 1 5/8ths" long tube headers. Ceramic coating optional, but highly recommended. Smog hook-ups as required.

Re: Which headers with these mods... (calebchoson)
Well the 1 5/8th would be optimum but they are hard to find pricey. I still do not agree that there is some mythcal gigantic torque loss with 1 3/4 headers. My personal experiance has only been a positive one and my car has plenty of torque. Dyno proven results are coming soon. So unless you want headmans or can afford Exotic Muscle then go with Hooker or TPIS. They are good quality and have netted good HP gains for many forum members.

having a healthy mod list certainly makes the argument for 1 3/4"............otherwise I would do 1 5/8" withouta doubt.

For my 383 I went with 1 3/4" Hooker # 2149.
They seem to work well with the 2.5 " dual exhaust, no cats to 2 chamber 40 series Flowmasters.

There IS no "mythcal gigantic torque loss with 1 3/4 headers." There is a factual, sacrifice of a torque gain that the smaller tube headers provide. having a healthy mod list certainly makes the argument for 1 3/4"............otherwise I would do 1 5/8" without
a doubt. For your sake, I hope that list includes somewhere up-wards of 50 cubic inches.

Thus your next (and not a bad) choice is the Hookers or the TPIS.

Re: Which headers with these mods... (VictorRussell'92)
Well, mister smarty pants, would you not agree that it is tough to find affordable 1 5/8th headers without quality issues? You always complain about people with the 1 3/4 headers
*I* have not shopped 1 5/8ths" headers and I am not aware of all the products available. Despite all the nay sayers, there are quite a few people on this forum that are very satisfied with their Hedman Headers. It would seen that many that reject the Hedmans, do so on their lack of the proper snob appeal.
...and Hedmans suck on quality.
"mister smarty pants" Indeed! :shocked:
