ok im in the middle of a engine swap from a v6 fi to a 350 carb, and im just wondering will the stock exhaust work with the new motor? its factory 2 1/2" i do believe, the 350 i do believe also has headers with 2 1/2" outlet, so they should bolt right up, but would there be any problems?

 

Step 1 of exhaust when swapping from V6 to V8: Remove all of the V6 exhaust.

Step 2: Install something that will work.

 

lol five, as always ty for the help, but the headers that came with the v8 r the same as the v6 exhaust, so do i nd to get new headers now? and if im remove the v6 exhaust, what should back on? is it the 3" pipes i nd now...

 

what?? how are they the same wouldnt there only be 3 tubes?

 

i have no idea, if u seen my other posts, both my new 350 and camaro r a mystery, its puzzling yes, so why wont the stock exhaust work? to small?

 

well yeah the pipes would be small and the y pipe would be different and headers on a v6 obviously are not going to fit a v8

 

like it says in the sticky NOW is the time to upgrade to a better flowing exhaust system.

 

ya ik ik but money is a lil tight, n dont worry im not gonna ask whihc system should i get, lol, but ik the headers r different but what im sayn is the headers that came on the 350 litterly bolt right up to the stock exhaust...so i was wondering if it would work, but im guess no now, so ill look for a new exhaust

 

hmm that's strange... if it bolts up i Would ride around temporary until you had enough to purchase something better

 

ya thats wut i was thinkn, i just wanted to now if it would hurt anyhting, lik the motor, or blow a hole in something n that causes damage to something

 

it won't hurt anything, but your brand new 350 will run like the v6 you just pulled out with factory v6 exhaust.

at the very least, scour the classifieds for either HO or TPI manifolds/y pipe.

 

ok thank you

 

Factory V6 is 2". Some aftermarket cat-backs use 2.5", even for the V6 application.

But, no way the y-pipe would bolt up to both - unless that also is aftermarket or custom.

 

hmmm most be aftermarket then...whihc is wierd, but then again i have come to accept that my camaro, is a puzzle in a puzzle in a puzzle

 

Sorry, I haven't seen your other posts. What's the 8th character of the VIN?

 

actually five u hav, uve replyed in quite a few, n i thank you for the help, now the 8th digit in my vin is...S
