TTP without tune?
Will the engine run optimally without a tune even though the O2 sensors will be malfunctioning?

My concern is running without a tune and the rich conditions that will result. I'm a bit paranoid, I wonder how much the stock ECU accounts for just a primary CAT delete. I really don't want to tune, but at the same time I have heard that running rich can be quite detrimental. |

You don't NEED a tune. The engine won't run rich. The WB02 are excellent and tell the ECU the precise AFR and the ECU has authority to adjust to the target AFR with or without cats. But a tune will help you make even more power.

I have the OEM exhaust mod done...the car sounds AWESOME, but 30+hp and a louder exhaust is VERY tempting, lol. I have to really think this through. |

Why can you not just bolt the stock cats back into place? Was thinking of getting these and just bolting the stock cats back into place when it was time for inspection. Is that not possible?

There is insufficient room on the cat to use a traditional band clamp. You could, however, weld the cat back onto the x-pipe for your inspection and then cut it again and re-install the test pipe.

Does everyone with TTP weld it back on for emissions testing? Or is there some other way of temporarily putting the stock cat back on (maybe another type of clamp)?

Bump to see if there is some other way of temporarily re-attaching the stock cat (e.g. for emissions testing).

it would liklely be easier to "borrow" or just purchase a new x pipe and swap it out for a day. Its a pretty easy install job.

Buy a used stock x-pipe and use that like someone else did. They are not expensive at all and easily swappable when you need to take it for the test.

Then you are spending $400 for a used X-Pipe, $400 for Turner test pipes, $100 for cutting and welding, and you still have to swap it back and forth for inspection if your state has OBD2 plug in.

Used x pipe will Be less than 400
Also, even at those prices it still is a good deal. It fits better than aftermarket x pipes and makes as much if not more power.

Maybe they have a long boat ride from Asia? You could have a set made by an exhaust specialty shop or make your own if you can weld.

It is great some exhausts are still made in the USA. Maybe that is why 2 eighteen inch sections of pipe cost $400. If the angle is 45, that would be beautiful. You could just buy two stainless 2.5 inch 45s from Mandrel Bending Solutions, Ebay, or elsewhere and a couple of flanges plus a 5 pack of stainless 02 bungs from Vibrant and a couple of flanges and just a little cutting and welding and drilling would be needed. I did not check the angle. You can also find 60s, but anything exotic would require some custom work.

Yeah, I don't understand the backorder issue, and yeah, they are making a ton on us. I bet those things are less than $100, they are just 1 bend and 2 02 sensor flanges each. but, they're 1/2 the price of anything else... oh well. I kept mine when I sold the first 2 cars, and they're about to go on the new one.

Holy ish they are still on back order! I tried to purchase one back in early December and was told it would be available in January; it's now Febuary, I also don't understand why so long a wait for a piece of pipe. I'm glad I canceled my order and purchased a custom piece for half the price. Just find a reputable exhaust shop that can build you a set of test pipe and have it welded to a stock Xpipe. I purchased a second Xpipe for around $200 and kept my stock exhaust in one piece for emission and resale purpose. I still paid less than $450 for Xpipe and test pipe do the job youself to save some $. If your not handy I'm sure a shop won't cost you much to install.
