Here is a question for anyone that may have did radix and everything first and lastly did LT headers.I Am very interested in knowing the gain.I have a few guesses but I would like to hear from someone that has proved on a dyno what LTs do on a SC truck. Thanks


Reason I ask is because it will be the last thing I do if I do it.Headers can be a pain in the *** and can be noisier than stock

 

I wish I could quote some dyno numbers from my Dynatech install. I can tell you this I went from 8.5-9 psi down to 7 psi on my 5.3, that translates to better flow.

I hope someone does have some numbers, it would be cool to see.

 

I have been holding my breath to hear from you and your results,I didnt know you finally did headers.Do you feel like you gained ? did you re-tune and did you change the tune much?

 

I did not have to change much, just a tick of fuel. Do I FEEL like I gained, YES on the top end big time.

 

I gained 10rwhp and 31rwtq after my header and exhaust install. only mods at the time were Radix with stock tune and stock 3.3 pully and a K&N FIPK.

 

Good info,which headers?

 

No dyno numbers but there is no doubt of gain for me. Track times from 14.2 to 13.8.

 

? I thought you were running 12.7 with your set up?

 

Stainless works long tubes. true dual 3" exhaust with Magnaflow high flow cats, X pipe and two 18" Magnaflow mufflers.

 

Thanks for posting this gonzo.

I was curious as well. I plan on ditching my AS&Ms in favor of some type of shorty style header for emmisions reasons and legality in Ca. I hope I'm not going to take a huge hit in performance.
