Where can I get an LT4 knock module and how much does it cost. Ihave pretty loud exhaust snd my brother told me i should get one.

 

Do a search on jason cromer and you can get one for cheap. Why do you want one in the first place? Your exhaust is too loud never heard that one

 

i would def. go to jason cromer to get it. that is where i got mine and he is the cheapest that i have found. do a search on his name and his number will come up. i dont remember it off hand. lata

 

the lt4 KM is not at sensitive as the lt1 KM. so, with louder exhaust, for example, the lt1 KM might pick up false knock. the lt4 was designed for the roller rockers which are usually a little louder so it was made less sensitive.

 

You probably dont need one IMO.

 

Very few people notice a difference from one...but it can't hurt. I wish I'd have gotten in touch with Cromer. GM loves to overcharge!
