This is a cold start.Once it warms up,the nasty tiny bit of rasp is nonexistent

my sig is still fine... ?

 

this thread makes me miss my old LT

 

Mine is a freak lol.quest for 12's in effect

 

I need to upgrade exhaust and get a bigger heat exchanger and dual pass. Im running stock dp. Its killing me

 

I'm still on stock exhaust manifold.i have a ported head. Still on stock endplate but have a massive fmhe

 

I was just coming in here to ask if anyone that went boosted was . I'm pretty set on going SCed and was wondering if I should spend the extra $600+ and get a header/dp at the same time

 

Ny LAP has sai. And its a different version where the ports are on the block. I had to cut the header to make it so it would fit around the bracket. Its deleted now so im thinking to get a bigger header. Im getting a 2.5 castles dp soon im hoping it will pick up a bit

 

You'll feel a nice difference going catless

 

I hope so. Ill be pissed if I don't run low 14s

 

Sure wish i had 2.5" exhaust instead of my stock 2.25" dp and piping back to my muffler lol i think it may be time for an up grade soon :-)

 

Im almost thinking of going 3"

 

i want to switch to a 2.5 but my gmpp sounds too ******* good to get rid of

 

it will sound even better as a 2.5''

 

You will lose a lot of low end torque with 3 inch.2.5 is perfect

 

you wont gain anything off only .25" anyways

 

Wrong.....flows much better. Especially with boost

 

this x1000

bigger is not always better. Take your mouth and blow air at a piece of paper; once through a pvc pipe, and once through a straw.

I suck at analogies but you get the point

 

3" works just fine for me...

 

And me too lol 3" catless FTW, Ill get a vid this week of driving down lower wacker (big tunnel lol, in all the batman movies), sounds amazing!!!!

 

Yes you are turbo. You flow away more than my sc

 

there are much better places to spend money to improve performance than upgrading the exhaust .25" bigger... GM designed that exhaust with the ss/sc in mind so you cant tell me that .25" makes an "omg i feel zeee powwwaaa" kind of difference. the difference will be largely unnoticeable especially with the power levels you 2.2 guys are at with your s/c's (considering you are on stock internals). The GMPP flows perfectly fine for anything under 300HP.. over that then 3" may be beneficial, but that gets annoyingly raspy on the s/c's unless you really like trying exhaust options
