Ok the new setup got finished yesterday!

My old setup was stock exhaust manifolds,Flowmaster 50 series single in/dual out catback system with stock tubing everywhere else, and cats, oh and stock fan.

The new setup is Pacesetter LT's(cermaic coated-black),Magnaflow 2.5" dual in/dual out single stainless mufler(pn#14568-22"-5x11), all stock tubing was removed and replaced with mandrel 2.5" all the way around(no more flat spots!), and cats were removed. Also LT1 fans w/Nelson harness was done. The turndowns had to be ordered and wil be put on in a few days. So for now its just open muffler.

I knew that these changes would result in some decent gains but they were drastic. Now that I look back that LS1 was seriously hurting to breathe! The TQ gain was obviously noticable but what suprised me was the amount of top end gained. Remember this is all by SOTP but it was that drastic. I had been reading that that muffler was quit even with no cats but that is defintly not the case with a LS1. I could say its loud but not that loud but that does no good since everyone has a different opinon. Its a hell of alot louder overall than what I had and at WOT its really really loud! Put it this way at park/idle before we raised the idle from 650rpm I set off 5 stock car alarm within minutes that where in my parking lot. I would recommend this exhaust setup to anyone -it is not quit but its def not hillbilly loud-its sounds strong. Ill be going to the track this weekend to finally get some times since I did the motor and Ill try to get some sound clips up Today. Also CRAZYCUTER4.8 thanks for taking care fo me!

 

Hell yeah, this is exactly what I was hoping to hear. That is going to be my plan as soon as I get some $$$ and Pacesetter makes their 4x4 version. I assume you are 2wd?
How do you like the quality of the Pacesetter lts?

Can't wait to hear it.

 

o baby cant wait to hear this i also want the 4x4 version they said early october get those clips going so we can hear them!!!

 

Yea man, that's great news! That's one of the mufflers I've been considering...I'm assuming it has an internal crossover/x-pipe? Can't wait to hear those clips...congrats!

 

Yep Built in X-pipe! On another note I got some SES's today- P0171(fuel system lean bank 1) and p0200(injector control circuit) My buddy is almost positive the p0171 is becuase of a slight exhasut leak I have(which will be fixed in a day or so) but I havent let him know about the p0200- I got the p0171 last nigth and we scanned it and he was almost sure it was the exhaust leak but I didnt get the p0200 untill tonight! I was reading in a previous thread where someone got that p0171 after LT's and unhooking the MAF sensor adn reconnecting it fixed it! Any other guesses?

 

Might wanna check the connections to the injectors for the other code, a few guys have found loose connectors/broken wire terminals.

 

Cant wait to hear those clips, going to get some longtubes really soon

 

Sounds like a badass system, the clips should sound great.

 

how much does that muffler sell for. would this sound good on a stock 5.3.

 

I paid $119 shipped for it. PN#14568
