  • nice man what size pipe you runnin

  • sweet ass truck but man throw a muff on her i had a 98 350 straight piped and damn they sound shitty in my opinion

  • @Dansz71sierra the cheapest way for bolt on HP. you can gain quite a bit from them. i dont have them on my 97 350 vortec sierra yet, but ive heard of gains of as much as 30 extra hp. in some cases,you might lose a little bit of torque at low or top end, the the extra hp makes up for it, plus with the torque yours already has, you probably wouldn't ever notice that little bit gone anyway. what ratio is your rear end?mine is a 3.73 but i destroyed my dif. and had to get a new one

  • the headers help at all? im thinking about a set for my 07 sierrra 35o with true duel straights

  • @FarmerBryant yuck, crackle only sounds cool on a split header straight 6

  • trucks are like people...if there not straight there gay!(:

  • @oulover09 lol i donno bout that one my 86 camaro i had went mudding a few time s if u get up enough speed u can skeet cross the top of mud holes lol but then again thats prolly why my motor only lasted bout 5 years of constant abuse
