no on both occasions. there's no need to go on the dyno at this point. All I have is full exhaust, intake, e-fans, valve body, and a tune. Nothing too special. Maybe cams soon but they rev all the way up to 7k so it would be pointless because my engine will never spin that high.

 

Have you had any issues with your pacesetters? Also did you feel an increase right off the bat installing them?

 

the install and the pacesetters was a PITA. I lost low end torque but it def pulled harder in the higher rpms. You wont lose any low end since you have a roots.

 

i lost low end with my shorts, so i hope i dont lose any more.. i thought LTS give you low end/.

 

long tubes gave me all around power, no loss anywhere.

 

But, with a tune?

 

Any one heard/ trired OBX headers?

 

they're great I would get them if I could. I run an OBX di/do and love it

 

why did you get the pacesetters insteAD THEN>?

 

can you run the headers with out cats?

 

yes you can run headers without cats. I got the pacesetters because they were a lot cheaper and didn't really care. Expect lots of drone without cats. My truck is frikin loud and I have cats but not too bad once you get above 65 or so.

 

Well i found a real nice deal on pacesetters that come with a y-pipe. I also found a nice deal on the OBX. Now i have seen proven gains with the pacesetters on this forums. So i am leaning towards them to purchase.

Now as the cat situation goes, what do i have to do with the O2's i see we have four, one before the cat and one after.

 

You do know that LT's will not pass smog here in California?

 

i thought they will.. all u have to have is cats i thought.. or a guy you can tip off lol
