Matt I am running SDs with the stock flex pipe and the only exhaust leaks I have is where I attempted to weld a cat into the downpipe.

SD as in Speed Daddy?

yes

Looking at them on eBay...I read somewhere that most headers come with downpipe but it doesn't look like this does..

it does. it just doesnt have a cat

Alright. I really kinda wanted cat installed like I can get from ZZP

Save your money and keep everything stock
consider these steps;

1-Scangauge
2-Headers (sd of course)
3-
A.) pulley drop
B.) autolite 104's (spark plugs)
C.)tune (before you drive the new pulley)
4- enjoy your high 13 sec car

$200 and no leaks here! they may have smaller primaries but seriously, whos running over 350 whp here?

buy a highflow on ebay and go to an exhaust shop. typically $70 installed

Highflow downpipe ?

highflow cat

Oh highflow catalytic converter. Then weld to the SD downpipe?

sd headers. but yes

yes then get a double walled flex pipe and a o2 extension for sd headers

ahh i vaguely remember 16. A time when lights underneath your car was cool. A time when 12" tachs were the s. A time when rice was rice. Be glad you werent 16 in 2002

The SD Headers on eBay though come with the down pipe. I pay somebody $200 to install headers then someone else $70t to weld cat on the DP, correct?

Link to flex pipe?

ZZPerformance - Interlock Flex Section #ZZ-FLEX

Thanks...why exactly would that be necessary?
