True Duals?
Hey guys, I just had a quick question. Is it possible for our cars to do true dual exhausts? I know we have the W-body so that makes things tricky. But I was wondering if anyone knew a way to make it work or if there would need to be some major fabrication to make something like that work. Thanks for any help guys

Anything is possible with some modification. IIRC someone on ls1tech has done it

I'll have to check that out. I appreciate it.

To get true duals on a FWD I won't say is impossible (just about anything is possible), but the cost and fabrication issues may be a large issue.
You might be better off getting headers or a PLOG, better downpipe and change the rest of the stock exhaust out. Just food for thought. |

See your looking at doing 3" all the way back. What engine do you have? From what I have understood sometimes to much exhaust will hurt your engines performance in that there is now not enough back pressure. Best of luck..
Excerpt from an article below: The most beneficial way to use a performance exhaust is on a turbocharged engine. When the exhaust gas can flows through the turbocharger with the least resistance as possible, not only will you gain power, but you will also get a wider powerband. Not bad eh. The turbocharger will spool up faster and will give the car more power at a lower engine rpm Remember to make sure to keep the exhaust size proportionate to the vehicle. If the system is too big, it can hurt the performance of your car, defeating the purpose of buying the exhaust in the first place. http://i280.photobucket.com/albums/k...ps2e2c3e48.jpg |

its been done before. ive never seen it on a ls4 car which i believe is what the op has. heres a link since this comes up all the time on every wbody forum, but no one believes its been done. ClubGP Message Forum troubleshooting
3 inch especially with mufflers should be fine. youre talking about a single exhaust for a v8 car. it may be a bit much for one thats bone stock, but im sure hell be modding it in the future. 1.8 rockers, ls1/6 intake, and a tune the 3" might be the way to go. if its going to stay stockish than 2.5 is enough. |

Yea, That was my original thought. I think I am going to save up a bit and just get a new down pipe and have 3" piping run all the way back to spintech mufflers with 4" tips. I think that should sound pretty good
As ZIPPY and 03SSLE mentioned, be careful about exhaust size. Not done right, you can have issues related to the mod. |

I just noticed you have a 2006 Monte, forget my statement about the PLOG. But the bottom line is still the same, you may be better off going a different route.
