I just had a set of Jet Hot 1 7/8 headers installed on my car. They fit, RUN and sound great. What a wake up. Time to return to the track.

Headers for the LSX > *

Best mod ever.

I just had a TUNE put in and now the full effect is really felt. A return to the Track and Dyno are in order.

Always a good choice! IMHO a good set of headers is a must-have for any V8.

I just upgraded my headers/exhaust (plus wheels/tires/converter) and gained .9 in the quarter mile.

Then where are yours?

Waiting on my goverment check!

That's a lot of waiting! lol

old thread but, does yours crackle reall bad,a dn did you put on cats?

They crackle really loud when you get on it. I have no cats+ y pipe. (TRACK USE ) and a cutout. It sounds SIC without the Y pipe( I fired it up at initial installation, but the y pipe is intact now...... Money well spent.

yeah i had to fire it with open headers too the crackle i can handle, but my muffler makes it sound like SHIT!!! im thinking mayber a diff muffler and if all else fails some high flow cats. did ther crackle get less after the tune, i need one severly

What muffler do you have Tim ?

And If you say Fuckmaster I'll kick you in the balls.

No.... it sounds the same. It sounds good. I am running a cutout just in front of a stock muffler.

idk i looked and it has NO numbers or anything stamped and i know slowmaster is proud of their crap and stamps them so i hope no it sounded good before now when i hit 2500RPM it get obnoxious

Mufflers? You don't need no f-cking mufflers!!!

If you want a nice aggressive muffler without the flowmaster burble or borla rasp, I'd recommend trying Spintech... I have a pair of their mufflers on the truck. I get tons of compliments on the way it sounds, although I'm sure the 408's lope contributes to those opinions.

The idle's a little high in this vid which reduces the lope, but you can get a general idea of what the mufflers sound like. I don't have any cats so that also affects the volume a bit.

other then the muffler multiplying the crackle i am getting attached to the sound LOL ill try somehitn becuase it wasnt nearly as bad open headers and i can here it poping in the muffler its strange. like cavitation LOL im going to get some new 3" pipe bent back to the muffler and try a diff muffler or two before i settle. it sounds GOOD at WFO though.

EDIT SinCity your truck sounds good.
