I'm about to start preparing my car to drop my 350 in and was wondering if I need to get a v8 y pipe for my manifolds or if I can use my v6 y pipe. I'd like to reuse my old setup because it's all new besides the y pipe and cat, and the. At will be removed for a straight pipe. Is this plausible or out of the question?

Nope, sorry. You'll need the proper Y pipe.

 

No, they don't interchange v6 to v8, totaly different engines. A cat back will pretty much work except for the cat flange style perhaps

 

but can I just get away with the y pipe interchange and use my new intermediate pipe and muffler?

 

I think that might work for you.

 

I hope so because my intermediate pipe is only a year old an my muffler is about 5 months old. I'm ditching my cat when I pull the motor and am going to have a pipe welded in place.

 

I'm uncertain of what the size of a V6 intermediate pipe is, but I'd "guess" it's small enough to be somewhat restrictive with a 350.

Think it's 2 1/2

 

I'd suggest that the performance cars were equipped with 2 3/4's (often called 3").

There you go, sounds good.

 

thank you for the help everyone. this will work till i can get either my single 3" pipe ran or my dual pipes.
