caution about the stillen hi-flow cats.

i had them on my car, did a pre and post dyno
my car had a lot of problems with the stillen cats, it had a downspike in the dyno curve everytime. i lost about 10 horsepower with the cats installed over 5000 rpm.

cut the cats out and created test pipes, the curve went back to normal.

the cats were bad.

 

Thanks for the input, i appreciate it a lot. Although i don't have an individual dyno for the cats, i still felt a good gain when only the cats were installed. But, you know how it goes, my thoughts are not solid without proven numbers.

Hopefully with all my mods (not including nitrous) i'll break 310whp.... But, 9,000ft of elevation might throw it off a bit :-(

 

Depending on the type of dyno, I wouldnt expect 310hp.

Just for reference I put down 262whp on a mustang dyno with md exhaust, berk hfc, injen intakes, and the osiris tune.

 

262 is a good number on a mustang dyno. Your car is badazz, very clean, n loud lol

 

Thanks!

 

need those vids....

 

^^^^ Yeah bro, i'm working on it lol my dumbass doesn't know how to load them up to the site....

 

I put on my Y pipe today. Added about 50 wheel horse power. I was spinning in fifth gear all the way to 140 mph.

 

Yeah
