Please note

Listing in classifieds is for Paid Members. If you can't see the link to click to post an ad it is probably because you are not a paid member. There are no commercial ads allowed except by site sponsors. All for sale or trade ads need to have a price. No listing for offers only, but you can list something with a price. Ebay is allowed as long as there is a "buy it now". Potential buyers can inquire about the item being sold. If the sellers description has an error or not accurate you should PM the seller and or notify a moderator. No negative comments in the classified sections. We all have opinions, but we don’t need to bash people for placing an ad that doesn't agree with our idea of value etc. Members should be able to place an ad without worrying about being bashed. Members listing items or vehicles are expected to stand behind their sale or risk losing classified privileges and possible access to the forums. We want this site to be a place to be able to trust the person we are buying from. The seller & buyer are solely responsible for the terms and conditions of the transaction.

William: I don't have my copy handy, but does the assembly manual show the tailpipe/muffler welded on the transverse muffler system?

Also, I've read that article Porterfield did on the ZL1, but check this: we ran the chambered exhaust on our Y-Camaro up until a couple years ago, and I went low 12.8s with it...I put a Flowmaster system on it as well as a rebuilt tranny and it didn't gain ET or MPH! Never could figure hat one out?? Anyay, it looks to me like the worst part the chambered system is where it flattens out to go under the crossmember...
