I have the pacesetter 4-2-1 headers in my 88 teg. They were about $160 I think... and I didnt notice much performance gain, a little thought. The real reason i bought them was because I couldn't find any other company that made them for the 88 teg. I'd like to hear some of your opinions on pacesetter stuff. Any one else have them? How do they compare to brands like AEM or even some of the more expensive brands?
