Siro big bore pipe

[Quinton]

I just installed the big bore on one of my T's and what a huge difference it made. I am even running the stock air filter. I will have the slip my MS filter on, off of my other one and see what happens.

Very much worth what I paid for it. I highly advise it.

did u have to do alot of tuning to the engine?also u mentioned u needed a different airfilter... does the pipe make the engine suck in more air or sumthing?

[Quinton]

Not much tuning needed at all. I didn't HAVE to use a different air filter, I just wanted to slip on my MS filter and see how much more it helped.
The sirio is an excellent pipe!

did it help at all?

I haven't tried it yet. It's on my other T. I am going to put it and an A/M head on it and see how it does. I'm already wanting the sirio engine now though. :D

Big bore pipe is a great pipe, gotta agree with you there. AYK, have you looked into crazy nut racing and Nova heads? They are lower priced than the Hardcore and I prefer them over HCR anyday. Better design and cooling characteristics. HCR is overpriced on just about everything except their skids. Anything you can get from them, you can get from unlimited engineering for only a little more and get much better stuff.

yeah ive looked at them but i buy almost everything through towers and that seems to be the better one there....
