Newbie with a few questions..

In NYS you can pass with high flow? Is there any advantage going dual exhaust over the single, cause the stock is single and i was just gonna do that, but if duals are better then hell i do that.
 
well a cat is a cat,eithier way you should pass. my truck was origanal for California,that was it has the single exhaust. for dual exhaust its a matter of opion.
 
Dual exhaust will give you better sound and performance. not just a matter of opinion proven fact. here in pa the emissions is visual inspection before 95. so if its there dosnt mean it has to work. lots of locals run a pipe straight threw there cats so there (lifetime)

As a matter of fact the exact opposite has been proven, a single 3.5" pipe flows more volume than two 2.5" pipes, also the single give's increased scavenging.
 
maybe true with 3.5 single pipe, although i wouldnt consider that a normal cat back setup. in fact good luck finding the pipe and then when you do paying through the nose for it. id love to see the specs on that though. What size headers were used for those tests? cats? mufflers?

My point is that for a DIY application you can make up a cheap set of exhaust that will out preform the stock single. and cost way less then a cat back system
 
Been year's since I read the test's, they were in Chevy High Performance, they have also been beaten to death in other mag's. All thing's equal (header's, cat), a 3.5" pipe has more volume that two 2.5 pipes, period, that's simple math. That's why they use one 10" pipe to bring water to your home rather than 15 2".

But yes, a basic dual system will perform better than stock. But a basic 3.5" system will perform best.
 
Well, if i did duals, im sure it would look cool and would sounds nicer, but then again, doing a single 3.5 as you say is better, and where would i mount the second pipe? If i did a single im sure i could use the stock mountings. The only exhaust i looked at in detial was my 03 civic. So im not sure. If i wanted to go 3.5 single. Where would i get the tubing? What cat/muffler/headers should i get? And i guess ill have to weld it together so i cant do it myself either way? so im looking at over 1k for it all?
 
no should be that much. in my opion 3.5 is an over kill,i am very happy with my single 3 inch.

prices on 3 inch stuff the cat was like $80 something(i think got recipts somewhere)
$82 from summit

and exhaust shop would probaly charge about $300-350 to weld everything up

so grand total; a little over $500
 
Alright whats the difference between the different headers? im lookign on that site and i see what looks like the same stuff but it ranges from ike 150 to 500 for a pair of headers. I looked at the hedman headers, street and competition which whats the difference? And i looked at the 40 series flowmaster? Now i saw cats on there but they looked like normal cats. Anyone know where i can get the high flow cat and 2.5 inch tubing for the exhaust? It still looks like im spending at least 800.
 
hmm, alright. What about the cat? Should i stick with the stock one or should i rumage around for a high flow? And if i go for a high flow where can i find one that fits? I guess welding is preferable over clamps? and im gonna need to have them bend it too so i should just get the work and tubing from a shop and ill find my own headers cat and muffler? Uh yeah so whats the difference with the headers? Hooker headers or hedman headers? Thanks for all you're help thus far. :bow:
 
Also, what kinda different lifts are there? I see people using blocks above the leafsprings which i heard isnt good, i was looking at "suspension lifts" but it looked like they used the blocks? I really know close to nothing about suspension so anyone have opinions on the best 4 inch lift? And is it easy enough to do yourself or am i gonna need someone to do it for me?
 
i recomend spending a little extra $$ on your suspention. I am very happy with my Tuff Country 4" Ez-ride lift kit. I got all 4 replacement springs. Its got everything you need except extended brake lines. After the springs are broken in they flex real well and offer a relatively good ride for a lifted sfa truck.
 
well i never did it before, but im pretty good at takin stuff apart and putting it back together. haha. Ill look into it, though im sure the brake lines are gonna cause a problem but i guess with any lift ill have to do it.
 
On the exhaust, with a single system, the most important piece is the Y pipe. A high-flow cat is a must on these older vehicles.

The best 4" lift is IMO a DIY 4x4 shackle flip and a set of B-52's up front.

As far as exhaust I would take it to a reputable shop and have them do it. Shouldnt cost that much. I would just do single exit and make sure it is tucked up as much as possible. The headers to get would be Hedman Elite #69830, go to summitracing.com and type in that number for the search. Those are perfect for our vehicles because with a lift if you have a longer header it will hit the shackle bolt and dent your headers.

For lift I agree with 52's up front and shackle flip in the back, except you will most likely need to also do crossover steering.

Definately get the Frame bolt in and weld in kit from ORD, otherwise it is only a matter of time before your steering box rips off from the frame.

If emissions were not an issue, Summit has a nice dual exhaust kit, hooker headers, and 2 turbo mufflers for less than $500. The kit gives you the option of having the pipe exit at the back of the rear tires or out the back under the rear bumper. I like the kit....not too hard to install. But from alot of searching on here, the single 3" exhaust is the best as far as cost, and clutter.

With the dual exhaust, if the motor starts giving me any trouble, such as head gasket leaks or such, I can tell which side the trouble is coming from.

I kept the 3" single exhaust set up in case I wanted to change it back.

Of course with the dual set up w/cats, it's gonna cost more.
 
I would go with single and a shop do it just for the sake of wheeling, you want it custom bent so it is snug to the frame and all so you dont tear it up on trails. But i am running duals with a y pipe now and I like how it sounds but I have already smashed one of my tail pipes.
 
i have a mechanic i know pretty well, ill see if he can do it, otherwise ill have to search around. I guess ill buy the headers, high flow cats and y pipe and have them do the rest. I guess i could get a y pipe on that site. I guess the biggest diameter closest to my piping would be best? Also, where can i get high flow cats? Ill probably be joining soon. Im not sure what you meant with the lift "52's"? Thanks for the advice thus far
