Front Y Pipe Question





You can just bang the guts out of the precats and put the pipe back on.
It takes about a 3ft long piece of old 1/2inch pipe to bend up to get around the bend, a hammer and about 15min a side of hammering.
Those precats will come apart and block the main cat sometimes.
That's the cheap way to do it. You won't have problems with inspections that worry about how things look either.

You could try one of the Ys from a mag but I sugget a good custom exhaust shop if available.
With my current exhaust system and all smog stuff in tact (except the missing pre-cats) my Vette easily passed Ohio's E-check dyno sniffer last month. And the setup is 49-state emissions legal, sorry you CA guys.
Hardest part for me was putting the car up on pin jacks.
Bolted right in and fit was good.
Recommend you buy the cat hook up kit, used a small coupler in it to hook up the air pipe to the old one.
A small copper pipe type pipe cutter comes in handy to cut air pipe clean, also.

OK quality, but the bends are OEM style crimps.
I also welded in a oxygen sensor fitting on the pass side for a wideband fuel meter someday in the future.
Change to the sound is great, cleaner sound, much less muffled.
Converter looks very open and high flow, lots of light compared to the stock looking through it.
Also will need some long bolts, washers and nuts because the cat flange isn't taped for the stock bolts. Just thru holes
