FastClass Posted June 8, 2011 Share Posted June 8, 2011 Anyone running an X exhaust or planning on one? A nice alternative and under chassie room saver http://www.dynomax.com/mufflers.php?muffler=ultraflox A Friend runs one on a full Pro Street El Camino. Great mellow sound at idle and cruising. A whole other beast when you hit to go pedal. Go`s 0 to stupid in half a heart-beat. This is`t it. He doe`t have the wing and has pulled the wheelie bars. But the bed set-up is very similar just to give you an idea. Quote Link to comment Share on other sites More sharing options...
680HPStroker Posted June 9, 2011 Share Posted June 9, 2011 Lot's of folks will chime in with their own opinions, but anyone who has put in an x-pipe system from Torque Tech has never been disappointed. They specialize in GM "A" body cars. Quote Link to comment Share on other sites More sharing options...
FastClass Posted June 10, 2011 Author Share Posted June 10, 2011 Heard the X system was the wave of the future. Replaced the H and was definitely the hot set-up. Quote Link to comment Share on other sites More sharing options...
72MC Posted June 10, 2011 Share Posted June 10, 2011 I read an article in one of the Chevy mags recently where they dyno'd the same engine with a X and H pipe exhaust. One ran slightly higher peak torque and the other ran slightly higher peak HP. Forget which was which. Bottom line/conclusion, the numbers were close enough that both were good setups. Not worth changing if you had one or the other already in the car. I wanna say, but could be wrong, the H pipe setup had better low end torque. - Dave Quote Link to comment Share on other sites More sharing options...
CrazyDavey Posted June 10, 2011 Share Posted June 10, 2011 there is supposed to be some science with the X pipe to do as Dave suggests but it's nothing you would probably feel on the street. The H pipe has always been used to remove some of the "rummble" that dual exhaust creates in the passenger compartment....in simple terms it's a balancing tube...

680HPStroker Posted June 10, 2011 Share Posted June 10, 2011 The nice thing about Torque Tech is all the hard work is done. Everything is mandrel bent. all you have to do is weld it up, install the hangers, and you are ready to go. Nothing to measure worrying about making mistakes with fabrication. I agree with Dave in that if you already have a functioning H-pipe system and it's the correct diameter for your setup I wouldn't change it, but if you are starting fresh, or you need to replace due to you need bigger pipes it's a much friendlier way to go.

FastClass Posted June 10, 2011 Author Share Posted June 10, 2011 Maybe OT maybe not. But seeing as I started the thread I`ll make the jump. I`m guessing it helps to equalize back pressure as well. Seem`s I used to read that some back pressure was necessary. Mainly depending on vehicle usage. Now it seem`s I am hearing that previous thoughts regarding the need of back pressure are wrong. That less is better. I see some beautiful machines here, that I guessing are run on the street as well, running some awesome times. What is the current thought on back pressure. The need for it.

rick graffrath Posted June 14, 2011 Share Posted June 14, 2011 put it on my zz502,was told it doesn't sound like a big block at upper rpms Quote Link to comment Share on other sites More sharing options...
680HPStroker Posted June 14, 2011 Share Posted June 14, 2011 Believe who you want. All I know is a Torque Tech 3.5" into 3" X-pipe exhaust system helped my 489 pump gas BB make 533HP to the wheels on a chassis dyno at 6,300rpm's(sounding as mean as a snake). If that don't convince you, well I can't help you. Quote Link to comment Share on other sites More sharing options...
FastClass Posted June 17, 2011 Author Share Posted June 17, 2011 You do`t have to convince me. I`v been sold on them for a while. Way to many wrenches and Hot Rod owners I know swear by them. Quote Link to comment Share on other sites More sharing options...
