wuddup.. i went down to gearhead in duneidun today to ask about headers and exhaust for my 90 5.0 gt. he told me 237 for catback 40 series flows. 120 for H pipe and 160 for shorty headers. i only have about 350 to spend right now and im not sure hwta to do. the guy i talked to told me i should go with the catback and the H Pipe to get that installed all at once, and just bolt n the headers when i eventually get them. sounded pretty good to me. what ne of u guys do it different? wait and get it all at once or go with catback, stock H pipe, and headers. i can get 2/3 just not sure. help me plz

if its stock.....take the 350 and go to race related or blue oval and get some 410s....biggest difference ull experience....it knocked 7/10ths off my 1/8th mile time.

 

I'd go with gears first also. Another thing to consider is finding some used exhaust stuff. You can get the headers and the H pipe in the classifieds, ebay or the corral probably cheaper....
