Ok headers are on the way guys. Now the time has come to go with exhaust.. MY PLANS, please give me your thoughts on if this is a over kill for piping sizes.. My plan is to run/make the y pipe set up.. 3 inch pipes from the collectors, into a merger, from the merge out a single 4 inch exhaust... Headers are 1 3/4 primes.. So am I over killing it by going into the 4 inch single pipe. Should I only run a 3 or 3.5 out the back of the merge to retain back pressure, or let it eat, with my current idea?? I know the damn thing felt great with open headers.. So GIMMIE YOUR THOUGHTS ON it..

 

I would do a 3" all the way back from the header collector, that is what I would run.

 

What true duals ???

 

yeap! That is what I would do.

 

Negative, thats out of the ??

 

if it ran good on open headers id do the 4" that your talking about.. youve got a blown 6.0 so i dont think hp losses are much of an issue. plus that thing needs to breathe up top.

 

IMO a single 3'' is too small for a boosted 370. hell even ls2 6.0 gto's have dual 2.5''

 

Good good, this is kinda my thoughts on the whole deal. This is going to be all stainless so I want it right the first time, know... Keep it coming

 

i know you are used to dealing with big pipes buddy

i would go with at least 4" if you are going single. my old man has a 289 with dual 3" without any problems.

 

aww thanks lil buddy... I knew I can always count on some good info from you .. BTW love the texts, priceless
