3.5inch Exhaust pics needed Guys plan on setting up my 3.5 inch exhaust soon and wanted to see if anyone had pics of there setups, Especially Y-pipes coming off Jet-Hot long Tubes.
Plan on running 3inch from the headers to a 3-3.5 Flowmaster Y collector and then 3.5 inch over the axle to a Magnaflow muffler.
Any pics would help, I have several but more wouldn't hurt.
When it goes over the axle I will have an adjustable plate system Very similiar to the Borla to adjust exhaust sound.

Isn't that just a WEE bit big for a SBC, forced induction or not?
And if your collectors are only 3" (assuming), then 3.5" will only be a waste of money. Imagine having a 3.5" ball, it just won't fit through a 3" hole. But a 3" ball will, yet it could care less if the rest of the exhaust is 3.5, 4, or 8". It'll still only be able to pass a 3" ball. Crap analogy, I know. You can only flow as much as the smallest tube/opening.
But if you have 3.5" collectors, then never mind
My initial question still stands though.

My buddy is running 3inch off his headers that are the same size as mine, into a 4inch system and last time I checked that car made over 730 RWHP, and did the quarter at 148MPH in a car he could drive on the street with a similiar setup to mine.
I don't know everythin about exhaust but for the power I will be making 3.5inch will be needed. To be honest its going on my bolt-on car for the time being.
3.5 inch SINGLE EXHAUST is about Equivilent to a 2.5 TRUE DUAL in Area.
Not at all my friend
