Re: pics of my dougs 1 3/4 LTs and X-pipe true duals!!
Look over your headers carefully. Just got a set from summit. The flange was not cut completely through only like half way and also had a really bad weld around the collector. had a finish nail sized hole in it. Sending 'em back for a replacement set. Not too impressed with the welding skill on this set, very sloppy! Hopefully next set will be better. Btw, idk why these are back ordered by summit, the label on my box from dougs is stamped Nov 12 2007!

Re: pics of my dougs 1 3/4 LTs and X-pipe true duals!!
my best run so far is an 11.94 @ 118 with a horrid 2.1 60' and running pig rich on the bottle up top(10:8 a/f). I WILL get those issues figured out before this season gets into full swing....my rwhp and rwtq says low-mid 11s if everything else is right, so we'll see but 5800ft altitude is not very conducive either

Re: pics of my dougs 1 3/4 LTs and X-pipe true duals!!
put it on the dyno today(free hookup
) the exhaust made a whopping 21.7 whp more over the 1 5/8 edelbrock shorty y-pipe, full 3" no cat to a flowmaster crossflow muffler setup I had before and sound a LOT better doing it too!!! that X-pipe with the magnaflows=VERY deep and throaty. So on motor it made 358.4 whp@ 6400rpms(could probably get more if i screwed with the carb a little more) and 367rwtq@ 4500rpms. On a 125 shot it made 476whp@ and 485.6rwtq but I know I can get more because the air/fuel ratio was reading 10:8 at the top during the nitrous pulls
so going down to the local speed shop tomorrow to pick up a jet assortment kit and shoot for around 12:0-12:4 air/fuel ratio and that "should" up the numbers a little i think. I'll then head back up to the dyno and see what it does. All the runs were on shell V-power 91 octane, 33* timing on the bottle, 38* on the motor.

Quick question, With the 2210's you have to modify the number 7 spark plug (on straight plug heads) do you also have to modify it with the Dougs Lt's?? Thank you.
