I've got 18x10's and 18x11's presently wearing 285/30 and 295/30's. Unless you intend to go to 315/30's in the back, go with 10.5".

The aluminum toe link has the same benefit to a PP car as a non PP car. It allows you to have more camber. If you want zero toe, than you do not want the aluminum toe link. Not knowing the real numbers, but providing an example. Let's say both parts provide the same range of adjustability...

Staying away from the semantics, here is an after market part that contains 2 catalysts. The first catalyst contains 400 cells psi and the second catalyst contains 200 cells psi. Between the 2 catalysts is an air gap. It is within this airgap that an oxygen sensor takes a reading. A similar...

Upon more research and conversations, it seems Todd's explanation is 100% correct. The stock housing with the OEM downpipes has 2 cats in it. G-Sport does make a 2 stage option that has a 400cell primary and a 200cell secondary. The problem is it's 3" longer and ARH has said there is not...

The OEM downpipes can be purchased today for $475 and $450. Hard to believe that after profit to the selling dealer, the material and labor cost to shape and weld the piping, there would be enough left for a more technical 2 stage cat assembly that contains palladium, platinum and rhodium.

Just because it's on the internet doesn't mean it's true, but..... Where are the 4 catalytic converters on a Cadillac CT4-V Blackwing? AI Overview The 4 catalytic converters on a Cadillac CT4-V Blackwing (3.6L Twin Turbo V6) are located in the exhaust system directly off the engine. There...

The primary cats are further upstream, closer to the turbos (untouched). The down pipes only contain the secondary cats.

A few of us are doing a group buy for ARH downpipes for our 4BW's. Join the group and get our discount. Here's a link to their products for the 5BW. PM me if interested. I just learned about cats while deciding on the ARH downpipes. The OEM cats are 800 cell, 400 cell is the least...

Very busy day, been on the phone for hours and learned a lot. I spoke with Nick, the owner of ARH. He connected me with a friend of his in Long Island that has two 4BW's, one as his daily and one as a track car. He says he loves these down pipes and said they are not raspy. Same tone as OEM...

Join us in the Blackwing Mods/Tech/Performance area. This topic is being discussed there now.

The Crest Performance downpipes are $1,650 with the crossover pipe and $1,550 without. Hell of a difference from the $2,900 for the ARP downpipes. Yes, they both use G-Sport cats. I had to dig into this price discrepancy. The CP downpipes state they use the Gen2 E300 cats, ARP downpipes...

OK, I'm on it. That's 2 confirmed. I'm sure the larger the group the better the price, so please speak up. https://americanracingheaders.com/products/cadillac-ct4-v-blackwing?variant=50862877147352

If you two are game, I'll make a call and try to negotiate a discounted deal for 3 of them. I would want a catted pipe. Anybody else want to join the buying group?

I've heard good things about the GiroDisc rotors, but haven't heard from anyone having used the Paragon rotor rings. I would guess the GiroDisc rotors probably weigh about a pound less each if you care.

Welcome! The drop is Swift Spec "R" springs. That will change the geometry in the rear requiring shorter toe links.
