LTH or High Flow Cats?

[mysta_sandman]

I recently installed a corsa x pipe and while it's awesome, I've been eyeing either High Flow Cats or LTH.

The only problem is MA requires O2/Cat Sensors.

Does anyone know of a work-around to this in the NE area?

I'm looking to gain some HP and eventually do an E85 flex fuel tune in addition to making the csr/engine more racuous.

Does your state require an emissions test? If it does maybe going with high flow cats is a good idea.

Lt headers and no cats..

Cat delete and flange welded onto the OEM cat for re-installation later. Not as much HP as LTH, but the next best thing. OEM cat re-installation is simple.

Aside from any emission concerns, and setting aside budget, another big factor between the two is tuning. For long tubes, now factor in the cost and requirement of an NGauge and a tune. High flow cats don’t require a tune, and good O2 extenders for the rear will/should keep the CEL at bay.

Yeah, emissions are the issue. Otherwise I'd go LTH and E85 right out the gate with a good tune.

Seems like Hi Flow is the winner for situation.

Boost kills cats even green cats. I had high flow cats on my car, i got rid them just in time before they blew. Would’ve been catastrophic if I didn’t catch it.

Aaahhh yes. This too! Although BLine is working on some in-house high flow cats, 300 cell, that they claim are going to hold up to anything. But they are made to replace the stock cat pipe section. Wouldn’t work with LT’s.
