Im about to take my car in to get an exhaust put on. Im getting a custom bent dual exhaust on my 3.2 using V mufflers. But I keep having second thoughts. Its such a nice newer car, i dunno if i should mess with it. It would require me to make another openign in the bumper too. Like I dont know if i sell it one day if it will be fine with my new exhaust. Some part of me says leave it without any major modification and some part of me says just do it. Whats your guys opinions. what route do you think I should go? Leave it cadillac stock, or get that dual exhaust thrown in?

Robert's right, took his advice and added the V exhaust. Even with the talk of lost torque, the new sound is intoxicating and it looks entirely stock. I took mine down to the dealership and let a couple of techs take it for a spin, service manager as well. Allagreed that it much improved the feel of the ride and believe more people wold order this particular mod if it were available at a modest price.

Wait...the V-exhaust is 2.5 inches. Are you sure you were sold a V-exhaust? :bonkers:

I'm sure you know the mufflers are 2 1/2" adapted to 2" pipes. Should work OK. Let us know how it goes.

if i had a 3.6 i would just bolt it up, but since i have a 3.2, im basically duplicating the v exhaust with 2 inch pipes instead of the 2.5''.

Well the loss of torque is for the 3.2L, ur 04 3.6L shouldnt suffer from that by installing the V-exhaust.

i was talking to my exhaust guy about loss of torque, and he said i probabl will lose torque with the big pipes, but he said most people would never be able to feel it. He asked me if I knew what 30ft lbs of torque felt like. Of course I dont know, he said dyno might show loss, but most drivers wouldnt really ever know. Im one of those anal people though. I dont want to lose anything, even if i cant feel it.

If you're worried about losses, then go with an after market system designed for your car. They are tuned to your application, and you should see gains in both hp and torque. Corsa and Billy Boat seem to be the best bet. What's a extra couple hundred bucks anyway???:bouncy:

The V exhaust is about $125 installed the Borla is about $1100. Big difference for me. I'm using my savings toward the CMS Hugger Headers.
You crack me up Robert. Buy a Cadillac, then worry about pinching pennies. Nothing wrong with saving some money though. :highfive: I just try to balance wants, needs, and costs. I would prefer to spend a little more to get exactly what I want. It it just like spending $40 for the TonyA or spending $250 for Volant. $125 for the V or $850 for the Corsa. I went with the later on both. Not worth messing around on a $40,000 car.:thumbsup:

i'd love to go for a tuned exhaust but money is simply the issue. $380 installed, comparative to 900 (cheapest Borla price i found) plus about 90 more installation. The 2 inch pipes running from cats to the mufflers is basically the Borla set up.

Affordability has nothing to do with. I have two new cars, the Cadillac, a Dodge Magnum and a vintage Corvette.

For the CTS as you can see in my signature I've spent a ton of money on mods and still going strong. But I admitt I don't just piss my money away and I look for bargins, plus I plan ahead. I started out with a TonyA intake as I like tinkering in the garage. $50 and it does dyno almost the same as the Volant on the 3.2 @ $250. Tomm found us a heck of a deal on the Volant at $234. On the 3.6 HaveBlue got better results with the Volant so I bought one. I spent close to $2000 on the V bumper with the painted grill. Close to a $1,000 on black wheels and the expenses go on and on. Now I'm looking at Pete's group buy on the Shorty headers. Over $2,000 when it's over.

But I'm always looking for deals and group buys. That's why I'm a successful businessman in the manufacturing business Didn't mean to crack you up..:D

the only difference between what you are going to have bent and the cts-v pipes (forgetting about 2.5 verse 2") pipes is the resonating unit. hopefully the v resonator or whatever else you use will be fine. i'm sure the borla resonator is just above emission legal to gain the best "pass-through" possible. if i didn't have the extra money i would have done exactly what you are doing...

curious to see how it turns out...

If the resonator puzzles you, you can replace it with the popular X-Pipe. It also picks up some more HP but at the cost of more noise.

SDMarine I think had the right idea here. I have the V-exhaust matched to my cats as if factory, SD suggested an X-pipe ,but said the interior resonance was a bit much, so he installed a magnaflow resonance pipe aft of the x-pipe and the sound was as before the install. Thats what my next attempt will be, move the resonator back and install an X-pipe in it's current place.
