Replacing J-Pipe with Test Pipe
Replacing J-Pipe with Test Pipe
Hello guy's, my stock J-Pipe is bent and it is not in a good shape I need to replace it very soon. I was thinking of getting XLR8 J-Pipe with the XLR8 Test Pipe. I know that it'll give me power but I am willing to know how much and will the car sound louder?
One More question, will I pass the Emission Test?

Depends on the "emissions" test. You won't get any codes/CEL. And a "sniffer" shouldn't notice any difference. BUT a visual inspection might catch you out; it's happened to other members.
Maybe a tad louder. My J-Pipe (ATLP) alone actually reduced a little drone; added the test pipe (ATLP) and got the little bit of drone back; I've got the hacked stock exhaust, no mid-muffler, after market resonator.
I did think the tone was a little lower, a little more growl with the J-Pipe.
I've had no issues passing inspection (visual) twice. BUT I did put the stock heat sheilds back on over top of the test pipe.

That is the sound that I am looking for.
So what your saying is if the Mechanic pick's up the car and sees that there is no 3rd Cat, he will tell me I cannot pass the inspection? If that's the case, my mechanic does not do that as long the Machine read's it normally and no Codes are shown it will pass right?!
I am assuming that I will get 10WHP to the wheels with the J-Pipe and the Test Pipe?

If the car doesn't throw a code, will the tech still have a look? Who knows?

Other states may just have a ODBII port scan and/or an exhaust sniff and if there's no issues, it passes.
Here's one local that got caught out: https://acurazine.com/forums/3g-tl-performance-parts-modifications-112/remove-third-cat-%3D-failed-inspection-758857/
Not to scare the OP off the mod. 95% of the time, you probabely won't have any trouble.

The j-pipe doesn't alter emissions. The test pipe does delete a cat, the third cat, but it is not a monitored cat. So in most areas, it shouldn't create an issue. Even if it did, keep the original cat and reinstall for emissions purposes. It will only take 30 minutes or so and it will bolt up to our XLR8 J-pipe.

My mechanic never looks under the car! He just connects the computer to my car and that's it.
Will the Excelerate J-Pipe and the TP fit and connect without any issues to my stock exhaust and everything? The only slight little problem that I have is that it is pretty rusted there, hopefully there won't be any issue. I will let my Mechanic bolt them on.

Hey guy's I got 1 question about Rims. I need to buy 3 new Rims because my other one's are beat up
(potholes). My front tires are 235/40/18 and my rear are 255/35/18. What size of the Rims I need to get, 18 x 8, 18 x 8.5, 18 x 9.0 or 18 x 9.5? For the Front and Rear. I would appreciate for a reply to this because I am not really sure.
Thank You!

There is no way of fixing them
sure there is. google wheel repair in your area.
1 is chipped around (when I bought the car )
can be fixed.
the other front right I hit a big pothole
can be fixed. (pending actual damage)
and the last one is scratched.
can be fixed.
