Oh there was definitely a gain in power.
Would not spin the tires before and smokes them after.
The access is a added bonus

Maybe I was just lucky I used 2.5 pipe and have less restriction now without cats and with the O2 in the same place as stock

Also with the x pipe above it is short of making it to the stock exhaust so the total price was $795, for a very nice exhaust I might add.
I just $395 less thats all Hilton, then spent an extra $5000 at Carls on other things. But make no mistake Hilton, removing the cats increased power and decreased weight.

X-pipe: $420
100cpi cats: $305/pr
Installation hardware kit: $30
Drop shipping from SLC: $40

So $795.

 

So Rob, Is this part of your "return to stock" plan for the GT?

 

Now imagine how much power you would get with a properly made H or X pipe? I'm running and H pipe that was mandrel bent and used to be sold by on of the vendors. Go it used on the forum for $75.

Since your H pipe is crush bent, it is not 2.5".... take a vernier and measure the narrowest spot on the pipe, then deduct the wall thinckens X2 and that's what the inside diameter of your $300 H pipe is. Do you have some clearer pictures the pipe?

 

Yep. I'm going to refinish the set of D90's I have for it, put the CD-2 back in, and put it up on blocks in the garage and go through the underside with Q-tips. Should be therapeutic. The motorsports X absolutely woke it up beautifully, it was the single best performance mod I tried on the GT. But the stroker has kind of made beating on the GT superfluous, and it's otherwise unmolested, so it's gonna be the stock car.

 

And according to UPS, this all shows up today...which is pretty wild, should have been tomorrow.

I may be up late tonight..or *cough* sick day tomorrow.

 

You've got the best of both worlds. A "purist" car, and a "Bat Outta Hell" car....

Perfect!

 

Hmm. Fedex says that it's still in Anaheim but should be to you tomorrow. Hold off on the nasty upper respiratory infection until early Thursday morning, cough cough.

 

Wilco. Will do a go around.

 

Mike, we need to go for a drive at some point. Weren't there some engine tools you needed to borrow?

 

Box got here at 3:58p, and im scrubbed and ready to go push on the loud stick at 6:13.


..not bad..

I just see, im gonna have to re-visit these attachments.


I personally like these:

And..when I pulled the stock unit..my OEM cats are just..a disaster inside.


we'll see how it runs now..

 

Well?

 

..just finishin dinner downtown here..


Its..siginificantly loud(er).

I have an 89 resonators, and RMB as well that came with the $4k car.

Ya...im gonna have to take a notch of bling off the note with other resonators, or a nice 2in-2out chambered unit at the rear.

Personal preference...


BUT..tomorrow I bet I pass smog now...I had -no- cats before.

 

Ah yes, with an RMB and small resonators it'll attract attention, alright. Didn't realize you had an RMB on there....

 

Bah..not your fault. But this does solve the primary purpose of "get new cans to pass smog"...and ya, I'll tune out the 3rd gen camaro ring this setup has soon enough.

But love it.

 

Fast work, you must be motivated...

You might want to keep the stock cats to pass the smog test (if they still work).
