VS. a Summit X pipe with the tight pinch in the middle. You can see how this will restrict your total exhaust flow...

hes back:-) lmao,,,,
going to report him to youtube today... got to wake up to this:

I have coined the term "The Village Idiots" to describe you and the other forum members who only frequent the forum to brag about your cars while never helping anyone solve their problems. It's really sad to see 15 year members who have only been "thanked" 250 times in all those years. That alone is proof of not being contributing members. In fact, the continuous bad advice you guys give to others is further proof of being non-contributing members.


Paul, after my boyfriend installed the ram air on his big block '71 he noticed his engine was fast idling at 1100 rpm every time he pulled up to a stop sign no matter how far he had driven. The choke butterfly had fully opened after the first few minutes of operation but after 30 miles of highway driving the engine was fast idling again at every stop. At first he suspected the cold fan wash was somehow cooling the choke housing enough to re-set the choke so as an experiment he put a big gob of A/C putty over the choke housing to shield it from the fan wash. When that made no difference he concluded it had to be the new ram air that was buffeting the choke butterfly just enough to lift the fast idle cam to its first step. And as he knows the so-called "double pumpers" are intended solely for 5000+ rpm track racing conditions and have no place on a street engine he's using a #3310 Holley vacuum secondary carburetor and he's also running the stock iron exhaust manifolds because headers don't provide any gain unless they're run open; something that is illegal for street operation and the reason why not a single car in the world has ever come with headers. He's also using a pleated "paper" air filter because he knows the K&N's are garbage when it comes to stopping the fine dust that destroys piston rings and cylinder walls. Have a nice day Paul...................

And now we find out he's gay....


He is watching this thread and saw that stupid picture,, that is what he is trying to defend... lmfao :-)

This has been my concern when looking at many X pipe configurations is that the X pipes I've seen restrict the exhaust flow to where it is almost like going from duels to a single exhaust and back to duels.
Your statements and the two photos clear up my concerns.
Thanks.

Bummer, I just went to Dr. Gas Exhaust and the web site shows that he has retired and is no longer doing business.
Any idea who picked up his designs and work?

Summit must have changed vendors because this is a Summit X-pipe on my exhaust.

Here is a video of my car with a 3" X-pipe exhaust with Thrush 2 chamber welded mufflers (Flowmaster knockoffs).

I agree. I just put my 3" exhaust together using the summit x-pipe and a bunch of individual mandrel bent pieces. This is what my x-pipe looks like

Yeah looking at Summit's website, it seems they sell many different versions/brands of X pipes.

I was just posting the one above to demonstrate the potential pinch point in the X many X pipes have. All depends on how they pie sliced/welded the pipes etc.. You can see how on some X pipes, they take two 3" pipes, then section them out and weld them together, and the middle of the X is more like two 2 1/2" pipes because they cut half of the pipe diameter out to join them.
