hello so as title says the truck is ok runs a lil rough at idle I put a magnaflow exhaust on it now it makes a pop noise I think it’s backpressure someone said there’s a leak in my exhaust somewhere but besides that trucks ok it shift wen normally cruising but when I step on it it will go rit up almost to red if I let it but will not switch when stepped on completely n my engine light flashes I get misfire multiple cylinder codes. Any ideas on wat that wud be?
