5.0L (1979-1995) MustangTechnical discussions on 5.0 Liter Mustangs within. This does not include the 5.0 from the 2011 Mustang GT. That information is in the 2005-1011 section.
ok so i got flows on my 90 gt i dumped them, but i had the guy cut the cats off the stock h piipe, but it still has one pair, the upper one?? i was thinking if i'm not going to pass smog anyways what if i run straight pipes to the mufflers what would happen??
Running straight pipes will be loud as **** and will get very annoying IMO, but i did it on my bronco when i had no money so i know where you are coming from
I have heard that running stright pipes will hurt your valves because of the cold air coming back in too fast and warping the valves, but i think if you have straight pipes all the way back you should be fine
