Default Stock Y-Pipe

I was wondering if it is possible to cut off the third cat an put in a straight pipe on the factory y-pipe... This should be pretty cheap to do an probally would yield close to the same gains as an aftermarket y-pipe.....

Not what i was talking about. Are pipes are already 2 1/4 so going to another .25 of a inch wouldn't yield much more... as i said a straight pipe would be perfect if the cat can be cut out... Haven't had time to look.....

Don't do it. It's actually a waste of time and money. I punched mine early on, made zero difference at the track. Actually our cats are very efficient. Its the bend that kills us, not the cat.

I would save up for a aftermarket, the save your Y-pipe in case you ever have emission issues, then you can pop it back in for the test.


Here is my Cattman and then stock vs the old school CE Y-pipe

Keep in mind that aftermarket Y-Pipes usually eliminate the sharp bend in the pipe that comes from the back side.

But if you don't want to spend $250-$300 (or more) for an aftermarket one, your or @06BlkMax's ideas are better than stock.

Yes it's possible. Just cut off cat at the welds and weld a piece of pipe in its place. Shouldn't cost anymore than $50. Good luck trying to find a shop to do it though. Most shops don't want to risk getting into trouble.

There are always multiple ways of doing things, bud. It really just depends on the way you choose to get it done. Instead of just messing up your stock, I'd buy a used y-pipe and install it. That way, you'll always have the stock as a spare in case you go back to stock, in need of money, have inspections, etc.

Save up and do it right. What you are thinking is useles... the aftermarket ones have much more R&D that prove decent gains.

Smog check will be fine with racingline y-pipe. You'll need to take off the CAI, if it's not carb legal.

Make sure the stickers under the hood are taken off. They state how many CATS the car should have

VS the Cattman that switch up the bend pipe to connect to where the straight pipe connected before. Creating a bigger turn/bend. I don't know if it really makes a difference because I think they are both great options for our cars.

Hey Apollo, I would think its the "crimp" in the setup-right after the flex tube by the hanger- is where you'd get power robbing perf., not the bend in Bank 1's pipe...I could be wrong, but it would seem that way....

Possibly, I wouldn't disagree to strongly with you, it is a nasty crimp.

BUT there was a lot of talk about this crimp in the Nismo Catback and it's affect on the exhaust.

Click the image to open in full size.

Click the image to open in full size.


I measured it, the pipe is still the same size, and I believe its there due to the fuel system, I also don't believe there is any impact. BUT this is the catback NOT the Y-pipe, so I'm not 100% sure of the affect

FYI THE STOCK CRIMP (not my pic)

I HAD THE STOCK CRIMP REMOVED, THE DAY I GUTTED THE CAT, IT MADE ZERO DIFFERENCE

That crimp and stock resonator make a difference IMO... When I went to 2.5" straight pipe from the racingline y pipe... With the stock catback system it is very restrictive, this is including stock mufflers though...

No, I think you misunderstand. If you look closely, I still had all the stock piping I had only removed the crimp from the stock cat back on the same day I gutted the cat. It didn't make any difference.

I agree that "That crimp and stock resonator make a difference IMO" thats why I have a Cattman Y-pipe and Nismo Cattback.

I agree that "That crimp and stock resonator make a difference IMO" thats why I have a Cattman Y-pipe and Nismo Cattback.




Then you mis-read my post as well.
Perhaps I might have... Either way my point is removing "crimp" and enlarging pipe, and getting close to mandrel bending as you possibly can does make a difference. With the stock setup regardless of what you do it probably won't because it's still stock throughout...
My basis for the reasoning is I upgraded each component at a time.
1- CAI noticed a difference
2- Raceline y pipe noticed difference- even with stock setup
3- added Remus mufflers- noticed slight sound gains- minimal performance- still stock from y pipe to mufflers.
4- added 2.5 straight pipe from y pipe to Remus- noticed major gains in sound and performance. I am truly happy with my exhaust setup.
Modifying the breathing system of a car is a process. Modified stock usually doesn't give back as much because the system is still designed for efficiency. I learned from the advice of others here...
But by all means I applaud your efforts to improve performance through your research endeavors....

Exactly. That's why I told him in my first post not to waste his time or money modding the stock exhaust. (been there done that) If your gonna mod the exhaust, you pretty much have to replace parts like you and I did Staggered, a little at a time it adds up. Intake - Y-pipe, cattback. oh yeah, it does make a difference.

^^^ This is pretty spot on, for anyone looking to mod you exhaust, this is what you will get.

So for your cattback you don't have resonator?
