What headers should i buy for a Procharged 306sb with about 10-12lb's of boost? LT or shortys? and what brand?

long tubes ftw!! I 'd go either 1 5/8's depending on how radical the build is N/A or 1 3/4 if it's really radical but 1 5/8's should be fine

LTnone

I like my BBKs quite a bit. They turn blue quick, but whatever. Install was a breeze. Unless you're pretty built 1 5/8 is the best choice

I have had BBK ceramics for a year - look like I just put them on.

LT's..... I went w/ shorties b/c they were cheaper and wish I'd just nutted up in the first place. LT's will have better power thru-out the rpm range. They will be a little quieter on the exhaust side, but not too much.

Go ceramic if you can afford it. I would get them coated on the inside as well at a local place or you can go w/ Jet-hot...... Most are just coated on the outside.

wow great responses, Ok well im deffently getting Long tubes, and last question are mac long tubes any good? ive never heard nothing good or bad about mac but there headers what can be differnt in headers? also im going to stay with the 1 5/8's ceramic coated... last question do these headers come with o2 sensor holes or will i need to cut n weld bungs in?

They come with O2 holes already. The Mac's don't have a solid bolting flange like the BBKs, each tube has it's own flange. A buddy bought some and they didn't fit very well. I have BBK ceramic coated long tubes, very nice pieces.

The Mac's will probably go on okay the first time, but if you ever have to remove them for any reason, they will be a major PITA to get back on.The primaries warp under heat since they don't have the flange connecting them all like 92greyGT was mentioning. I would go w/ BBK or better.
