Ok new engine making 360/370. 650cfm carb, hedman elite headers. Will 2.25 dual system work good?

 

2.25" dual flows about the same as a 3" single, so yes it should work fairly well up to around 370-400hp.

 

Cool thanks alot

 

there is no exact horsepower level. you need to be more specific with the engine. mainly cubic inch, camshaft specs, head flow numbers, runner size, etc. id put a 2.5 inch on and be done, depending on the cubic inch. if it is a 383+ i would say 3 inch because then u have room for more improvement without choking the motor and having to pay for exhaust twice.

 

350 CID, 76cc heads with 2.02"Int/1.600,Hydraulic flat tappet cam with .480" valve lift, performer RPM Intake, 9.1 Comp. Nothing special.

 

id go with a nice mandrel bent 2.5 inch system and call it done.

 

Also keep in mind if this is a daily driven car, dual exhaust systems run under a thirdgen lose ALOT of ground clearance. With your "nothing special" 350 I think you'd be better off with a good 3" cat back system. It will save you alot of headaches. Just my .02c

 

X2, thats what i did with my trans am. Everyone i know except one person who went duals regrets it due to lack of ground clearance.

I am running a 3" catback and love the fitment and ground clearance. From what ive heard my 327 will no be choked up from the setup

 

X3. 3 inch will be the way to go. Plus the 3" single pipe gives a deeper tone than 2.25"

 

would i have to get a custom y-pipe for my hedman elite shorties, (ball and socket flange)?

 

nope summit sells a y-pipe that fits.

yea but thats a 2 1/2 single, if i wanted to go with a 3" Y to a 3" intermediate pipe, does anyone make one of those? because it just doesn't make sense to run a single 2 1/2 or run an expander at the end of the Y to make it a 3". Or at least thats what i think? idk lol
