CB Performance has a very nice stainless steel 1 3/4" merge in limited supply. It fits so nice.

I dont know if you actually asking the right question, because the header that might produce the most peak hp would be a larger sized header and a stinger. This would however loose low end TQ and make a lot of noise.

You could have one system that produces the highest peak HP but another produce the most total power when looking at the area under the whole power curve.

As far as I have heard the sidewinder makes better TQ than it does peek HP.

Its hard to find many people here that have even put there engine on a dyno once, let alone done it twice with two different headers to compare. If they have never done compare and comparison test there just guessing.

Exactly

For a street car i'd go 1-5/8"

Thanks all for your comments/help... KRUSHER & GLEN: thanks, makes much smarts. What would u guys recomend? Looking for something for a "weekend Monster" type deal. May cruise from here to there on the weekends but mostly seeking HP. to run at the track (besides a stinger)

I've got a Berg 1-5/8" with dual QP muffler on my 2180.

Her's mine, it sounds just fine... listen to the first 10 seconds.

Fit and finish on the Berg is top notch.

Also the pipes are moved out so you can run the factory thermostat and use Thing lower tins to close of the gap.

2276cc, 48 IDA's, CE heads..................

What cam and compression?

Dammit Glen!!!! I had started to forget about my berg header being stolen 2 weeks ago from my shop!!!

I agree with Glen the berg merged header has a great fit and finish

I run a Bugpack 1.75" ceramic-coated merged header with A1 Magnaflow muffler. It's quiet at idle, but throaty when you stomp on it.

169.2 HP at the wheels, 2332 cc, FK8, IDA's:

Here's a couple sound bites:

Just run your exhaust threw a turbo & forget the muffler. LOL I have run the Berg 1 5/8" & a 4-tuned 1 5/8" ( which is no longer made) & a pair of dual tuck unders that really sounded cool. I think your best bet is to call A-1 mufflers & tell him what you have in your motor & have him help you decide what size to go. The sidewinder is nice & up out of the way. It will be plenty big for you. It also comes jet coated inside & out for a real long life.

look no muffler !!

I just ordered my 1 5/8" sidewinder from AJ for my 2275.
I am interested in street drivability, not total HP.
If all you want is peak HP, go big.
I thought that if you match valve size to header size you would be ok.

Well, I feel in my case the 1 3/4" will be benficial to the engine in need. BUT, I also purchased a new GB 933PS 1 5/8" merge just in case! If I make it to XX Tuning in Hartford, CT for Dyno time, I can test both pipes on my 2387cc and will post up the feed back.

I used to run a GB 933PS 1 5/8" merge w/A1 single on my street 1776cc, 7.3:1CR, 40x37 Steve Tims, Dell 40's and MSD. I see no trouble in running the 1 3/4" on a much larger 2387cc, CB 044 large ovals 44x37, Dell 45's and 9:1CR.

Don't be afraid to try things out for yourself, after all every build is different. :wink:

Who sells the header with flanges that bolt together at the J-tubes? The slip ins seem to always vibrate loose.

I have never experienced that problem. Are you using a quality header?

Sat Nov 22, 2008 2:08 pm

Would a set of 1 5/8 headers made for heater boxes bolted to j-tubes clear the tins?

Depends on who's headers you have.

and high temp silicone?

I have seen many manufactures offer their headers with heater boxes and it would seem that if the heater box clears the tins, the j-tubes on these same headers should as well. Just a thought...

This is much like the whose heads are the best argument. Headers have just as much science behind them and a true "best" is based on many factors. Here is a basics article to give some idea at whats involved. Although primarily for v8's it still is worth a read.

I am using the A1 on my current project as it has the best balance between
performance and appearance. Were it not a sleeper car I would have used a Berg system.
