Got the exhaust and valence! The valence has a screw on each side with the head to where to can not get it. Pain, but took pliers and backed it out - the rest just comes right off with male/female plugs. When I put it back on put ties thru each hole - 2 - where the reverse screws had been.
Just finished installing the factory V6 exhausts to my 4 cylinder. It looks great now, but what a pain (same word used multiple times). I thought it was going to be a direct swap, but the 4 has a cat in the line and the V6 does not. Perfect if you want to run cat less, but I wanted no codes.....so I cut the stock exhaust off right beneath the back doors and then cut the V6 muffler and pipe at the same place and hooked them together. In theory, it should have worked....it didn't. The driver's side pipe was sticking out further than than the pass. side. A trip to a muffler shop fixed that, they heated the pipe behind the muffler and bent that around and then cut off the shorter tip and made it longer. Looks factory now with the dual valence and all. I put photos up on a kodak site, if anyone wants to look at the 2 pipes off the car and how the car looks now, send me a email to [email protected]. Looks great, but what a pain!

On the topic of dual exhausts....you can build an 09 with the performance package which iincludes the dual exhausts and put the 4 in instead of the 6. The only issue is that if you choose the performance package with the 4 you get no credit for the engine which i think is a bit of a rip.

Good job on the install.. How about difference in performance.. Ive heard that by going dual you will loose back pressure on a 4cyl and have power loss.. I know alot of imports that happens to if you do not have any power upfront to make up the difference in the larger amount of exhaust flow.. Have you noticed any difference good or bad?

ok, did you try to run the exhaust with no cats? is there an o2sensor after the cats on the stock 4cyl? is there a place to put the o2sensor on the 6cyl pipe? just curious. thanks....oh and please send me pictures to [email protected].

No O2 sensor. I used the 4 front section with the cat. I did not want to run any codes. Will send invite to see photos.

No difference in performance that I can tell. It is almost identical, its too bad you can't just buy the muffler for a V6, that is all you need and the valence. The single pipe goes all the way back to the muffler. Only duals is an additional pipe exiting the muffler to make it duals.

I could not find this, can you tell me what else the performance pkg includes? Thanks, Bob

 

[2wlhyp]

awsome! thanks for the pictures, im going to get this done soon, also i dont think any codes will come through since there is no o2 sensor after the cat.

Thanks Bob! The dual exhaust looks perfect!! Looks like you have to buy the whole exhaust pipe and the muffler with the pipes connected. How much does the whole set cost?

Still waiting for the Pics

Bob,

go to chevrolet.com and build an 2009 malibu LTZ (build a 2008 and when the page appears go to the address bar and change the "2008" to "2009" and press enter. Then go forward and build the car you can select the performance package which includes the V6, dual exhaust and a few more things and then you can select the 4 cylinder instead on the next line down.

You are welcome, looks great and no effect on anything else. Just the shipping of such a large piece - guess its hard for it to arrive without any bends you don't know about until you put it on the car!

No you can't, that does not exist. Maybe you're seeing one of the common glitches in the build system, but there is no performance package having anything to do with an LTZ, just the V6 package that includes the 3.6L, dual exhaust outlets, and hydraulic steering.

Otherwise, nada. It doesn't exist. 4-cyl Malibus come one way, aside from trim level, with the only differentiator now being the 4-speed vs. the 6-speed with it. No other option is available, as talked about above, in the glitch. When you click the V6 package it should lock the 2.4L checkbox out, but it doesn't due to an error.

I thought it was a little unusual to hear there was a performance pkg. I bet I have the only 4 cyl. LTZ with duals! Thinking about taking the LT off and just leave the Z. Then it will be my Malibu Z parked next to my Z06 in the garage! I think that would be kinda neat to do. What do you think? Maybe I would generate some questions about the Z pkg option!

Love my 4 with the gas prices the way they spiked due to the hurricane in Texas. My prayers are with everyone down there around the Gulf. May God Bless all of you.

 

[2wlhyp]

would you happen to have the part numbers? thanks

Ross

 

[Grapes]

Beach, you can opt for a 4 cylinder with the performance package.

 

[Malibu Bob E]

would you happen to have the part numbers? thanks

Ross

Sure, the rear dual valence is 15831263, the exhaust assembly is 25922925

Thanks for the parts numbers Malibu Bob E.
