what are your plans for the car?

xSxTxAxNxGx · September 24th, 2007, 03:56 PM

i have to keep the ztock manifolds so all im doing is getting a custom mid pipe and dual exhuast out the rear, but im stuck on the custom work at the shop or just buying a kit... :-( i need help on what to get i just want a deep tone

AtlanticBlue99 · September 24th, 2007, 03:58 PM

get a catted H pipe and magnaflows for a deep tone. if you want it loud, get an offroad midpipe and magnapacks or other nonbaffled mufflers

JASonic · September 24th, 2007, 03:58 PM

They put 2.5 on with my Flows. I didnt know any better at the time. I suppose its better if I ever mod this thing anymore.

u should be ok its probably from the muffler back any how. but if u run 2.5" on a N/A motor u lose alot of back pressure and it rapes ur low end.

AtlanticBlue99 · September 24th, 2007, 04:00 PM

2.5 isnt harmful, it just supports more power down the road. but you want the flow of the exhaust pipes to match the flow your engine is creating.

i have 2.5" pipes. SSMS car has 3" pipes after the collector pipe that turn down. the flow of the motor determines what size. there are charts to show the support of diameter piping and hp:

Nice link THX

I did see a slight "drag" in low end power. After I got the CAI, I got some of it back ( no facts, just a butt dyno). I did get a boost in high end power though. My acceleration above 70 is definately better.

I thought they told me 2.5.

I could be wrong though.

more importantly, are the pipes mandrel or crush bent?

How do you tell? What will the mandrel look like?

AtlanticBlue99 · September 24th, 2007, 04:14 PM

mandrel are same diameter through the bends. crush are narrower when a bend occurs because it is cheaper for shops to buy/use crush benders than mandrel benders
