Lately I have been researching x-pipes. But There doesn't seem to be a lot of reliable and/or scientific information out there on the benefits if x-pipes. Silverbullet runs an x-pipe and after hearing his car I'm so tempted to get one for my sc.

What is everyone's opinion in regard to x-pipes? Are there good sources of information I may have over looked? What are the HP gains of x-pipes?

Comments/question/criticisms welcomed!!!

 

Remember my X-pipe doesn't effect the sound too much; it is before the resonators and mufflers. I also have resonating tips. There are a lot of books and articles about crossover pipes, X-pipes, H-Pipes, different designs tombalance the exhaust so the two sides of a V8 don't compete with each other to grt the gasses out with minimal back preassure. Check out the racing exhaust manufactures like Dr. Gas ... They have their explaination. I didn't do dyno testing only the X-pipe alone rather the before and after for entire exhaust system; OEM vs Custom. If you want my sound you will need the same resonators, mufflers, and tips ... Try a resonator delete and see if you like it. Not much money to test that.

 

Thanks for the explanation. Seems like x-pipes produce more power but it's not possible to predict. Are you saying I should delete my reasonators for more sound?

 

I was thinking of getting an X pipe installed as well. The guy at the muffler shop told me that an X pipe would be better for top end and H pipe would be better for low end. He also said the H pipe would sound more like a muscle car

 

Yes I have heard that as well- h pipe better for low end and x pipe for high end. But the only person actually running an x pipe, as far as I know, is SilverBullet. I find many opinions of mechanics questionable, since many don't have direct experience wit our cars. The only solid evidence I have to make a decision is the x-pipe that SilverBullet is running from Dr.gas..

 

Bacardi also has the Dr. gas X-pipe. Read the design sheets, not all X-pipes are equal - all depends on the interior airflow and how they get the exhaust to efficiently crossover to the other side in a balance and sync'ed fashion.

Greg x-pipe looks really nice. I just wish I knew what kind of power gains to expect. Guess that's just part of the process of car modding, ie, don't really know what you are buying until it's installed.
