i recently cut my entire exhaust set up off and installed true dual straights with high flow cats that i dumped right in front of the rear axle. my dad, of all people said that there is the possibility of me burnin up my valves due to insufficient back pressure. bottom line, am i driving around screwin over my engine with this set up??? please help i can't afford a new engine!!

 

it dont sound healthy but definitely keep those 2 cats on there

 

You shouldn't have a problem with your set-up. The valves will be fine. Technicaly your stock exhaust manifolds will have enough restriction just keep your cats and mufflers.

 

He doesnt have mufflers. note *true dual straights*

 

Good point. Sorry i missed that. I was thinking more about the backpressure and what would hurt the valves. Might want to add at least a muffler.

 

well then he's right back where he started, with a muffler.

 

i'd put that muffler back on man and save up your money to get true dual 10 series H piped bc i know youre wantin it loud. Then put high flow cats on or delete 2 of them. im gettin my front 2 deleted as soon as i have time to go do it, ill let you know how it sounds

 

He started with a different setup so he wouldnt be the same. He also added high flow cats now. Correct me if im wrong but 04+ have 2 cats. You should think about headers and mufflers (or h-piped) and it would still be pretty loud.

 

My bad, or is it 05+?

 

i have an 06, and before i put the high flows on i had one 16" cat to each pipe. After some research i decided to keep my high flows and put some sort of muffler on there, i just dont want to dampen my sound too much, im young and dumb so i want my truck to talk haha

 

Trust me, i got the "talk to ya" exhaust problem also. I kinda like the poppin it gives me back. You can find a nice muffler that doesnt kill that sound you love but if you want loud, add some long tubes.

btw, high flows-good choice

check-louder without cats#3 forum-explains what you might want

 

You should be ok with the hi-flow converters. As long as theres some type of cat system on it you'll be ok.

 

true dual 10 series.

 

Your engine will be fine, you have 2 cats on it and you have plenty of pipe to help with flow. If you like the straights you can keep them and be fine, however if you would like to gain some power back I would suggest an x or h-pipe.

 

okie dokie, thatks for all the input yall, i really appreciate it!!
