Default Y Pipe Size for the New QTP Headers(Grots)

Working on a Y Pipe to use with the reintroduction of the Grot Header. Now known as QTP Headers. I want to make a quality Y Pipe and want to gain as much power out of it as possible. So I want to know what people want. 3" or 2 1/2" Vote and add comments if you like.

I'm looking for a whole exhaust - headers, cats, y-pipe & catback.
Has to have all emissions fittings and should be about as quiet as the stock system. What have you got and how much power increase over the stock system? <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

My custom y-pipe made locally for my Grots is 3" into a 3.5" FM collector and then into a 3.5" --> 3.0" Hooker reducer

I voted for 3 to 3.5 to 3, seems to make the most sense. Now, why not make a custom X pipe setup as an additional option :-)

More info on the Dual QTEC Y pipe part mentioned on the board? Please?

Also, how did this come about, did Grott finally go belly up and sell/give you the rights to the design?

personally as i have already ordered a set from barry he called to discuss options for this possible y-pipe that he had taken into consideration, and i feel that a FM dual 3" in and 3.5" out would make the most sense and most power. opening up to a 4" from a 3" just to go back to a 3" sounds confusing just saying that and thats what your exhaust would have to cope with using that set-up. im leaning more and more to the idea of some dual QTECs on there now though too <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

I have Grots with the ***-ugliest Y-pipe ever seen. I had to paint it black to hide the welds. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> [bought headers used, Y-pipe came with it, was built by somebody's brother or something]

I'm in for a 3" - Flo 3 1/2" collector. I was going to have it done anyway, but if someone comes up with a plug and play piece, I'm there.

3-> 3.5 makes the most sense.

Will an option for cats be worked in with the Y pipe?
