well i need headers my truck tells me so i went to my exhaust guy the other day and i wanted to get a custom y pipe and said it would cost me $250 bones and i want headers down the road with magnaflow hi flow cats with a custom y pipe with headers i asked which would be better shorty and longtube he said shorty on the hemi .He said he could get and install the headers and y pipe and cats for $1500 canadian heres the headers

http://www.summitracing.com/parts/EDL-65893/ there edelbrock tri coated ceramic short tube

http://www.summitracing.com/parts/MPE-94109/ magnaflow hi flow cats

the exhaust guy said it most likely gain 35-40 to the wheels with all three of these done with the y pipe

tell me what u guys think

 

lts are better for the hemi. shortys have minimal gain for the price. you can get coated pacesetters for 430 and then their coated y pipe is 180

oh and your exhaust guy is full of chit

 

That sounds like the correct range of HP gain, they did some things with them on a car magazine online and that's about what it did on the dyno.

Now... my opinions. I would've gone with long tube... just what I've heard over and over on here that long tube seems to be a better deal to go with and just keeps the exhaust flowing more evenly.

I'm going some exhaust work myself here in a bit. I'm putting on some LT Pacesetters that are ceramic coated and a performance y-pipe.

Just my .02 again, I wouldn't mess with the cats... I was going to get ride of mine but just too many problems. Cats are pretty much high flow and paying money for a new one that is replacing a working old one isn't going to get much bang for your buck.

Just keep us up to date on what you're doing... the most important part is to have fun with it. I like to do all my own work, that way I know what's going on with something. I think I learned a lot about my truck within the first week of owning -- replaced two pulleys and changed the oil along with tweaking a couple things here and there. Now... if I don't want to mess with it, or want to blame someone else for screwing it up -- I let the shop mess with it.

 

well seeing how your from alberta i wouldn't even bother putting any cats on your truck. im gonna be getting mine cut off soon. and that does seem a little pricey to do up the exaust like that.

 

what makes you even think about believing this guy? Sounds like an idiot to me. He's absolutely wrong about shorties being better for the hemi. In no way shape or form is that true for ANY engine.

I'll address the issues 1 by 1.

Headers - Get longtubes. end of story. The only reason you should get shorties is if you have emissions standards that require you to keep the cat in the stock location. Pacesetter makes the best header for the dollar. They're by far the most popular around here (i have them as well). Dont cheap out the headers either. Get them JetHot ceramic coated. Not only do you get better performance (lower underhood temps), but the longevity of the header is increased tenfold, especially with the winters up there and the salt on the roads. Salt eats metal. Salt doesnt eat JetHot ceramic coating. Plus they're look as good as the day you bought them even 10 yrs later.

Cats - you dont need em. I took mine out and so do a lot of people. Some will say you lose a little low end blah blah blah. Its a mental thing. You dont lose anything. Its more of a hassle to put them back in anyways. Use sparkplug non-foulers in your rear 02 sensors to get rid of the check engine light after removing the cats.

If you MUST have cats, use the stock ones. They're already high flow. Getting the magnaflow high cats is just burning mod money. Put the stock ones back in and you'll be fine.

Y-pipe. If you're gonna go catless, get the pacesetter off-road y-pipe as well. Its a perfect fit pre-bent, designed to go with the longtubes. If you decide to go a different route, a shop shouldnt charge hardly anything to fab up a new "y". You can also get a magnaflow "y" for cheap on amazon and have them put it in.

I installed the longtubes and y-pipe in my garage. It all bolts right up, no fabbing necessary. It'll save you a lot of mod money.

Above all else, dont go back to that guy. Hes an idiot and hes takin your money

thx for your imput guys i really apreciate it ill look up the pacesetter lt

question if i get the cats gutted would that throw a cel from the o2 sensor after the cat is that were i use the spark plug foulder trick to make then read that the cat is still there.Would that mess my af ratio up? sorry dont know much about this area

Is it even worth it to gut my cats for power gains
Will it make my exhaust lowder and make it pop and crack

wow thx silver now i just need to find a vendor here in canada i apreciate this

 

I you get the pacesetter lt's you know you will have to modify your stock cats to get them to work. The pacesetter's have 3" collectors and the stock cat is only 2.5". Personnally, I went with the high flows then sold my stock cats. For me it was easier bc the high flow was already 3" and I didn't have to cut and weld my stock cats. Then in the end I sold my stockers for the same that the high flows cost. Just another option to consider.
