What's the best Y-pipe for QTP Headers? I have QTP 1 3/4" Long Tubes and a GMMG catback.
I'd like to have a 3" to 4" Y-Pipe with a High Velocity Merge Collector that will accomodate 2 Magnaflow High Flow Cats and if possible dual cutouts before the cats with a 4"-3" reducer for the GMMG. I have a Global West TracLink Torque Arm that I will be installing, so it will also need to clear that.
Does anyone make one like this? My WS6 is stock ride height. I doubt I will ever lower it because of the roads here, but I still want good ground clearance for speedbumps and such.
Thanks.
Also, what's the best header gasket?

I'm actually thinking of selling my L92 motor and swap parts and going with the combo Rapid Motorsports sells for 346.
Originally I was gonna go with an LG Motorsports G6X-3 cam and send my heads off to TEA to be CNC ported and Milled and a spring upgrade, but LG won't disclose enough info to me about the cam to know whether I'll have PTV interference problems with the L92 Pistons. They said they've only dealt with LS3's and the L92's pistons are different, so they have no clue w/o checking them...and they're not gonna disclose any cam specs that might be leaked out. Plus...god only knows when the L92 FAST intake will be out. LG has got some great results with that cam on LS3's but I'm not willing to pay what it would cost for me to have LG do the combo on my motor. It's just really frustrating trying to build a stock displacement L92/LS3 combo with all this "secret squirrel" bullshit surrounding these motors.
Then Rapid Motorsports posted the 502/445 dyno results of their Dominator 2, milled TFS CNC 215's, and Ported Fast 92 Combo. I wouldn't have to flycut my pistons. Just bolt it on, tune it, and smile! Plus being able to get those kind of numbers with a 3.90 bore "dinky" motor is appealing to me.
So I don't know which direction to go. What do you guys think I should do?
