Yes, I agree. I've thought about having v-bands instead of the three bolt flange setup (I believe gnvair did his that way?).

If you have had a chance to drive your car after installing the new logs? Do you notice a performance increase? Cost?

David

Yes I drove it and I do notice a decent improvement. It is more willing to rev and is very happy on the highway. The best explanation I can give is I would do it again.

The logs were 225-250 it was three years ago when I bought them. The u-pipes, clamps, hangers, exhaust packings and Flowmasters clones from summit ran 110.00.

I am very happy with the results.

No, unfortunately David doesn’t make them in stainless (at least last I knew).

Cool, glad to hear about the results.
I couldn't find him on ebay.
Any clues?

Thanks,

I reached out to the guy. He is going to give me a call. Thanks for letting me know they improved the performance.

Are you able to install the lower covers with these?

Mike, I do not know his ID one eBay. I spoke to him over the phone.

Ron, Yes I have the lower shrouds on and the heat works. I took the car for a couple hour drive the other night when it was in the low 30’s and I stayed toasty warm. I can take pictures later and post them. My main reason for going with these was to retain the heat.

If any of you are in the Chicago area you are welcome to come check it out first hand.

I wonder if these would add any performance to a 110 PG.

I wonder how much of a power hit I would get if I use them in place of my headers. I'm running a isky 280 cam. Might keep it from revving as high. I would like to get heat back as well as allow it to get to operating temp better, and control it better.

Ron, I am sure there would be a noticeable improvement. Any time you improve airflow I assume you can expect a bump in power. It may require a jet change and/or timing adjustment.

I am running 4 Rochester's with 50 idle jets in all 4. I am also running Seth's distributor with timing curve of the 140. I haven't put an O2 gauge on it yet to check the mixture but it seems to be running great.

Will, It has been a while since I had the headers on my car so my memory is rusty. I will say I was not as 'WOWED' as I was when I had the headers. I am sure you will notice a little loss in power but I could not say how much. What size inlet/outlet mufflers are you running? If you are running 2.5" then I would expect to see a loss, it you are running 2" inlet/outlet mufflers then maybe not as much.

The mufflers I have are chambered 2" inlet/outlet. It may be a bit loud for some folks but I like my car to be a bit loud.

Keith I see you too have the Otto Carb Rotator kit. I use Thrush chambered duals. They are a bit loud but outside they are passable. I wouldn't want anything louder. I guess they grow on you. People have said it rumbles and comes to life at half throttle like a small block V8. smileys with beer Mike

Keith - Why don't you dig out the parts list from Summit and offer it as a "guide" for someone who wants to build one. U-bends, flanges muffler sizes, etc.

Seth,

Excellent idea!

I used a j-pipe that is 2” diameter tube and a 4” radius. I cut both ends a bit to get the muffler where I wanted it. The part number from Summit racing is SCH-020018J-40 and is $14.99 each.

I used the Jones Exhaust Full Boar Flow Deflector Performance Mufflers FB2042. It is a chambered muffler with a 2” center inlet and a 2” offset outlet. The Summit Part number is JEX-FB2042 which is $36.99 each.

I used the Walker Mega Clamps 33974 for the 2” pipe. It is summit part number WLK-33974 and is $9.99 each.

I picked up two universal turn down fail pipes from O’Riellys. They were $9.99 each but I do not have the part number for them.

I used the factory 140 muffler hangers. The drivers side was a direct for. On the passenger side I turned the factory one upside down, had to cut part of it off and drill a hole to line up to the head. It worked out perfect.

I welded the j-pipe to the flanges David provided. First mount the muffler, bolt the flange to the log, trim the j-pipe to the correct size, fit all together then mark the pipe on the flange in three spots so I welded it it the right spot.

I tacked it in then refit and tested before final welding.

I think that about covers it.
