Hell no!

 

hey lizzfan, if i go with the mac LT's what midpipe would you reccomend?

 

I have the O/R H, it's up to you tho. Just make sure it's for L/T's

 

I would love to do an o/r h-pipe but then inspection becomes an issue... i looked on mac's website and i couldn't find any catted h pipes so i dont know what to do.

 

yea, Mac did away with them a while back. Tho Mac says you have to use their mid-pipe exclusively you can find another brand that'll fit

 

bummer... hmmm i'm not sure what to do because my car is due for inspection in june.... do you know any other good headers for an auto tranny that have an catted h pipe

 

bbk with their catted h would work..bbk has desent quality too

 

where i get my inspection, there is no sniffer (NY), so i use the o/r h with homemade mil's for no codes. if that doesn't work, down to the junk yard for two similar cats, cut them in half, and strap them around your o/r h for the looks of a cat for visual inspection. if you do have the sniffer test, there is no other option then real cats...

 

what has to be done when installing long tube headers on a 99 gt

 

I think bassani, Kook, and edelbrock have been proven to show the most gains...

With the edelbrock header showing more gains than even the other two... something like 12rwhp over macs..
