I consider the Super Turbo to be reasonably quite , quieter than the Flowmaster 50 series Delta Flo I took off.

The high temp stuff from POR doesn't go on over rust like the POR15 rust paint. The metal needs to be rust free. I used POR20 which is the aluminum colored coating and it is by far the best high temp coating I have used, it lasted for 3 years and 20k miles before starting to break down . Much...

FYI, I put new headers in a couple of years back and ordered the Remflex gaskets. On the drivers side they were thick enough to cause the header to contact the steering box. Wound up using a Fle-Pro gasket on the drivers side and Remflex on passenger side. Both have been leak free for the past...

If you already have them why not mock it up and see if they fit or can be modified to fit.

I have hedman 1 5/8" headers three tubes on the drivers side wrap under the center link but in 45k miles they have never touched anything on the street. I slow down for speed bumps and drive around pot holes but I do that anyway so its no issue. The hedmans tuck up well and fit with no...

Every brand of headers are goint to be a little different in what is required but here are my recomendations; 1. You need the car up in the air 2-3 ft so the headers can be slipped into place from below. 2. Other than TTIs and Dougs the steering linkage goes through the tubes so you will...

Because the power required to drive at low and cruising speeds does not change putting the 4bbl on won't change anything, the engine will be throttled to allow the same air flow. Now under WOT acceleration the 4bbl will allow more air in so more exhaust will be coming out, don't be surprised if...

IMCO is also the company that makes the exhaust kits that summit and Jegs sell. The kits come with mandrel bent pipes and IMCO turbo mufflers for a little over $200. I put this exhaust on my car last winter in place of the compression bent pipes and Flowmaster 50 series mufflers. Can't tell...

Glass paks are straight through mufflers, the only difference between the traditional glass pak and the mufflers mentioned is the size of the case which provides for more packing and a quieter longer lasting muffler. There are some real cheap glass paks that have a smaller iternal tube than...

They are the originals offering the ceramic coatings for headers. I believe they are one of the few that offer colors other than silver and black. Nothing magical about doing these coatings, seems most places that do powder coating are doing the high temp coatings now. I stopped by the...

Since mid 05 and almost 40K miles I have been running a set of $150 Hedmans. Can't compare them to anything else performance wise but; They fit well, have been leak free and the fact the three of the tubes on the drivers side wrap under the center link is just a non issue. I can't imagine...

The Summit kit I received back at the beginning of the year was made by IMCO (had their name on the box), the company that owns Maremount Exhaust and Cherry Bomb. Don't know if Heartthrob is connected to them or another company.

The price you pay for the ease of installation of a shorty header is you won't get anywhere near the power you would get with long tube headers and they are only marginally better than stock manifolds. FWIW, I have had Hedmans on my 68 Barracuda 4spd car since Jul 05 and almost 40k miles. In...

I have the 2.5" system on my Baracuda. I also installed the Summit x-pipe. From the mufflers back it fit well. Because I was also installing the x-pipe from the muffler forward I did a fair mount of cutting and fitting. This system replaced a compression bent system with a home made x and...

Just for a point of reference: Before I put the 360 in my Barracuda I had a built \6 with 6 into 2 headers and a full 2.25" dual exhaust with glass paks and no cross over. The exhaust was to loud for me, you couldn't carry on a conversation at cruise, and at WOT it had a nasty sounding roar to...

An X or H pipe will reduce the level of drone and yes muffler choice has a big impact on how much drone you get.

Back pressure is bad for any internal combustion engine. But going to big on the pipes can actually slow down the air flow enough that it effectively increases backpressure by reducing the scavigining effect and will lower the power output. That being said on a mild small block the only thing...

I have used H and X cross overs and I can't say that I can tell any difference in power from no cross over. But, they have made a large difference in the sound. They have reduced the volume of the sound across the entire rpm range and they have smoothed out the sound and lowered the frequency...

FWIW, the advertised air flow numbers of a muffler are the last thing you should consider when choosing a muffler. It's the easiest parameter the manufacturers can jockey with to meet their marketing goals. Air Flow is only valid and meaningful if it's given with the pressure drop the number was...

I just installed the 2.5" Summit kit and there were only 12 joints you could put clamps on and that is what they supplied. The reason for all the joints is so it could be shipped in a small enough box so as to avoid over size shipping charges, a good thing in my book. I used two band clamps...

Something is real wrong there. My tubes don't come any where near the torsion bar and the way the tubes and the closest part of the idler to the header tube is the top where the grease fitting is. Are you sure you have the correct headers?

I have a 73 spool mount K-member and a 360 in my 68 Barracuda with power steering. My Hedman headers fit fine. When I swapped from manual to power steering I used a 73+ steering box which required the 73+ pitman arm, idler arm and center link. This style has the posts on the pitman and idler...

I am running Hedman headers with power steering in my 68 Barracuda. The headers clear everything just fine. I would recomend that you pull the steering column to install them though. It makes it some much easier than jacking the engine out of the mounts and trying to wrestle them in and will...

Unless you are racing an looking for every .1 second you can find the butt dyno makes perfect sense to gage changes. The generally accepted number is 3-4 HP to be noticeable by your butt in the car. As far as my car having 370 HP it's never been on a dyno so the number is an approximation and...

The headers I have seen for Dakotas and Rams are shorties that put the outlets in the stock location so you can hook up a stock y-pipe. The outlet on the drivers side interferes with the steering column. If you are looking for a good fitting header for short money get Hedmans. They are around...

FYI, no engine is going to see an improvement in power by increasing the back pressure, that's an old wives tail. The full exhaust improved the overal tuning of the system to allow the exhaust to more efficiently get out of the cylinders compared to the open headers. To the OP regarding tube...

FWIW, I had a 2.5" compresion bent system with 50 series flowmaster mufflers. Some of the bends were real bad reducing the cross section by 1/2. I replaced it with a 2.5" mandrel bent sytem with turbo mufflers. By the butt dyno I can't tell any difference. This is with a built 360 that was...

Your butt dyno will not be able to tell the difference between the 2 1/4 and 2 1/2. I would just install the headers and down the road if the money presents itself or the exhaust needs replacing go 2 1/2". The only thing 3" will do for you is make more noise. My Barracuda orignally had a \6...

The kit from Summit and the Jegs ones look the same are made by IMCO. IMCO is the company that owns the Cherry Bomb and Maremount exhaust brands.

I installed the Summit kit. It replaced a compression bent system with 50 series Flowmasters. I find the Summit mufflers quieter every where than the Fowmasters and I am very happy. I got the same drone at 1600-1800 but it's much less pronounced than the Flowmasters which I thought wasn't bad...
