Let's talk exhausts.

[emil77]

I guess the next project is to make Betsy sound better. My exhaust pipes are showing alot of rust. I was reading thru some of the past threads here and I'm kinda confused and have some questions.

1) With my older engine, will a new exhaust sound good?

2) I want to have the dual exhaust exit out under the rear bumper, that won't be a problem, right? The shop can just go straight back instead of the stock exit's behind the rear wheels?

3) Do I need a X or H pipe modification done?

4) Should I have everything welded in?

5) Now the age old question: Which exhaust? I had Magnaflows on my Dodge 1500, loved the sound of them. I don't want Flowmasters. LMC sells a Magnaflow kit for $579, price will be more with oversize shipping. I don't want to spend that much. Some previous threads suggested going to an exhaust shop and having them make one for me. I want a nice deep ruble, I don't want to have a headache from the exhaust

6) Any other suggestions I would appreciate.

What year is your truck and did you have to modify it much?
cause i didn't see it listed for anything but elcamino,chevelle etc.
Thanks

1) Yes, it will sound great!!
1A) What type of engine do you have? 283, 350, 400, 454?
1B) is it stock? has it been modified at all?
1C) Headers? Stock manifolds?

2) Shouldn't be a problem for any decent exhaust shop to run your exhaust to the rear bumper.

3) Depends. To me it's always been; higher the horsepower the better off having an X or H pipe section. I have a stock GMPP 350, so I chose not to do one.

4) My system is welded, but I'm using Stainless Steel, so I've reduced my Rust factor. Pros and Cons on both sides of this issue.

5) That's all up to you. I had a shop do mine, cause, again, I'm using SS. It really depends on what YOU want and what you've budgeted for.

6) Research all the video/audio you can from the web.

I'd have an exhaust shop do it so they can run the exhaust through the crossmembers.
how it's going to sound depends as muh on the engine as it does the exhaust.
headers and x/h pipe are for the high performance guys.

[Low & Slow]

Im confused. I bought a muffler for my project and had a shop weld up custom pipes for $175 including hangers and a resonator.

$600 seems steep. I'm new to trucks so maybe I am overlooking something.

There is a big price difference between aluminized steel and 409 or 304 stainless steel. Maybe the 600 neighborhood he was talking about was a stainless one.

1a) 350 engine.
1b) I haven't modified it, but on the valve covers it says "Crower Racing Cams."


If I go to a shop and have them do an exhaust, how will I know if it will sound good? I just want to avoid the exhaust having an annoying sound which will give me headaches.

Thanks for all the info, keep it coming!

[brad_man_72]

if you go to a shop you can have them test fit and run the truck w different mufflers. I'd definitely make an appointment for something that time consuming. I'm sure if you took up a rack half the day on a sat it would cost more than on a monday. Look for a shop that specializes in hot rods, they will be more likely to understand the need for your truck to sound just right. Might want to bring a few pizzas also anything helps when your more of a pita than their normal customer.

[SCOTI]

The $600 'kit' might also feature mandrel bends vs. typical exhaust shop pipe bending (mandrel = consistent ID of the pipe in bends vs. tubing bends which will partially collapse).

I would buy the mufflers you want/like & leave the pipe to the muffler shop that does the install (if the slight reduction in ID on the bends isn't of consequence). Stock-ish 350's won't see a dramatic power difference. The cross-over (x-pipe; h-pipe) helps tone the exhaust note down slightly @ cruise speeds.

[jamesi20]

The magnaflow kit is stainless and it is mandrel bent and has a true x-pipe.My truck is a 70 with a 350/350.The only real fit problem that I had was I notched the trans. crossmember to get the pipes up and out of sight.With the style of clamps they give you I didn't feel the need to weld the pipes.If you have minimal skills,this is an easy install.When you call summit racing,tell them what your truck is and they will get you the right kit.If I remember correctly,they were actually shipped from magnaflow.The front pipes are long,you will probably have to cut some off of them,and my truck also has headers,which also made the install a little easier.

[emil77]

I'm going to be taking the truck in for an alignment on Saturday, the place I'm going to also does exhausts, so I'll ask them what options I have also.

Great info, keep it coming.

So, it sounds like you bought it this way, right? If that's the case, does it have Headers or stock manifolds? Reason this is important is because if you have Headers whatever muffler you choose will sound louder, due to the more free flowing Headers.
And, if you have stock manifolds, then you can get away with a little more aggressive type muffler, BUT....you keep saying you don't want "headaches", so on that note (pun intended), I would recommend a standard turbo-type muffler you can get at any auto store.
Before I chose my Hooker Aerochambers I did a ton of On-line research. I had stock manifolds when I had the system built, so they sounded great, but once I put the Headers on....WOW!!
My truck went from a "That's nice" to "Your truck sounds NICE!!".
As I said before, do some online research, go to shows/cruise-ins and if you hear something you like ask what they're using, but most importantly, it really depends on what you want it to sound like.

[emil77]

Great info, thanks guys. So you guys are saying I can buy the Magnaflow muffler and have a shop do the pipes? If so, do you guys think that will be a cheaper route? Does anybody know if I can buy the muffler that's in this kit separate? http://www.summitracing.com/parts/MPE-15894/

[AustinScott]

I just went thru my install, Its what I wanted.... a tab bit different than what you are looking for but the same concept. I bought the mufflers & had a shop do the piping.

Thanks for the info, nice sounds!

what's the average on a custom dual pipe job for our trucks?

Mine was $200.00, with an H-pipe. Mine does exit before the rear tires, but the shop who did it said it was $200.00 flat not matter what I wanted done, with the exception of stainless and mandrel bent tubing.
