It will affect your 02 sensor readings. Even if your only reading on the front sensors and not using the rears.

That's why they created the High Flow cats. They don't slow down the exhaust flow as much but the down side, at least to the emission people, is that they are not as effective.

 

So where do i get these fake cats??

 

Thise frozen boost cats look too big...

 

Those would be similar to the OE cats in the later years. The early years had round cats how ever when you replace just the cats they sell you that style as a replacement.

If you want OE style round you will have to find a set and break the sub straight out of them.

 

Hell for space i was thinking the thinderbolts at 47.50 a piece and knock the substrate out...

 

Or $52 with the o2 bung...

 

Found fake cats at another site too for less than half what frozen boost has them.... Is there a vband that has a seal, everything ive read about vbands is that they leak, if you can feel a leak in va is will fail....

 

Anyone with half a brain cell can tell by smell there's no cats, even the high flow aftermarket cats I had on my ARH you could tell wasn't stock by smell.

 

Thats a good point, hence reason i will most likely go with either the thunderbolts or magnaflows depending on funds at the time... Still need to decide what best connection would be either way its gonna have to be welded up whether i go vband or ball/socket type.... Rather have gasketless just not to have to deal with blowin gaskets

 

I would weld the whole exhaust up solid, just like stock.
