Corsa for Escalade

[TechSupport]

So Corsa doesn't offer an exhaust for 15/16 Escalade. What could possibly be different between the Yukon and the Escalade that it doesn't fit? Other manufacturers list the trucks together for their systems. Anyone try it yet to see if it fits?

They said they are not going to make 3.5 but I'm going to keep trying

Hey Tony what are they saying no to the 3.5?

 

[NORCAL SS]

Yes. No on 3.5. I'm gping to try again or what else they need.

Here's my thoughts on the 3.5" exhaust. I think GM did 3.5" knowing how restrictive the stock system is to help it breathe a little easier. After all the few aftermarket systems I've looked at "other than the magnaflow you sell" is smaller than 3.5". Could it be their mufflers have better air flow? I may just be a dumb railroad electrician but I know there's more to air flow than just the diameter of the pipe.

Tony, Please don't be offended by no means am I trying to put you down. It was just something I was thinking about today.

 

[NORCAL SS]

No prob. No offense.

I asked Corsa about this a while back and when they emailed me back they said the 3" system they have for the Denali won't fit because the side skirt on the Escalade is lower than the Denali.

Translation: any grease monkey with half a brain can bend the mounting brackets a little to make the Denali system work on the Escalade. I'm just really holding out for a 3.5" system from them...

I don't remember if it was here or on another forum that someone did install the Denali system on their Escalade.

My 2009 Tahoe with the 6.2 L9H has the 3.5" factory exhaust and no one makes a kit for it.. I called all of them.

I had my exhaust shop install a Flowmaster Big Block 50 Series 3.5 in & 3.5 out, both offset and it sounds great.. no reason to change the exhaust pipe, just install a good muffler.

I left my resonator on and it is just a bit louder at idle, has no drone cruising at 75 MPH and sounds very healthy when I get on it..

Good luck,

TC

I have a MagnaFlow on my Calllaway Denali 15 and it is deep and loud inside the truck. I also have a 14 Callaway Escalade with a split 4 rear outlet MagnaFlow Exhaust which is a bit quieter.

I just got the Corsa for my 15 Denali XL work truck. I really like the sound of the Corsa from what I have heard.

It's not koolaid.

So if a 3" flows THAT much better than a 2.5", it'd be the same story between a 3" and a 3.5".

That AND the fact that I currently have a 3" KPE catback on my Escalade and while it sounds mean as hell, it DID lose torque pretty much across the board.

ill try to make a video of the magnaflow cat back tomm night. Finally have a chance to get this go pro going

 

[TechSupport]

I find it very hard to believe that companies like Corsa or Borla would sell their systems without dyno texting that they make more power. They would be out of business. I've never owned anything from KPE so I can't comment on them.
Seems we need and exhaust comparison done with the dyno.

 

[NORCAL SS]

I know what mine made exhaust and intake vs stock truck. Cora and others don't dyno.... but I know that it's a first for paying over 1000 for a kit that's smaller then stock

 

[TechSupport]

It's funny I wanted to try and keep this one stock. That didn't last, I was looking at the airaid Jr. Kit with KPE resnatoer delete. Now I'm looking at the K&N Blackhawk with Borla or Corsa Cat back. Tony I've been watching your posts on here and on another forum and you got me thinking again.

 

[cardude2000]

Could you share the before/after dynos? I'm trying to figure out what to do for a catback. Thanks.
