Well I guess it really isn't another option you have over us (LS4 guys). We have the Magnaflow kit, and ONLY the Magnaflow kit. Good luck with this system. It looks awesome!

 

I just found out that this won't work with the 05 exhaust???!!!!! I talked to the parts guy at Libertiyville Chevy and he knows his stuff. Why would GM go to the trouble to change a last year design? I can put this system on my 03 and transplant my Dynomax that's on my 03 to my 05.

 

That does seem quite strange. I'd take a look and make sure for myself. I can't see it being any different.

 

ya that is pretty strange that they wouldnt be the same. montes my python, any luck with getting the monte de-winterized and a sound clip??? i cant take the waiting anymore?! i need mine to be here haha.

 

I went to finish the install today an low and behold the extention (front) pipe is 1 1/2" short, I don't know if the GMPP system is short or the aftermarket downpipe is too short, so I made a spacer from 2 flanges and a piece of 2 1/2" pipe, a little welding, 2 gaskets, and 2 4" x 3/8" bolts and done, now just to put it in
I don't know if this a problem that anyone else who gets this system will have, probably just the combo I have, but an easy fix

 

so if you order that cheap exhaust off GMpartdirect... it's a magnaflow exhaust system?

I'M really gonna need to hear a sound clip, because half the price of that Borla for another big name is WELL WORTH IT if it sounds good.

 

YUP

I'll post a sound clip as soon as its finished, keeping my fingers crossed that it sounds magnaflow good

 

thats correct blacksheep. i wonder why gm doesnt advertise magnaflow on the website? im sure they would sell much more systems if they did. for anybody who hasnt read this or emailed the company, its a shot in the dark (at least it was for me).

 

the system is GM part #12498617 and can be ordered from any GM dealer (doesn't have to be Chevy) if you can get a discount at the dealer, it'll be cheaper because there is no shipping charge. List price is $640.00, still cheaper than Borla or Corsa

 

Im gonna buy this system up this week. How long did it take to ship?.. Can't wait to here a sound clip!!
