Will this test pipe fit the TL?

looks pretty similar to the atlp one for 125$...

Not likely, it MAY fit if the flange bolts line up, but looking at the way it's cheaply constructed I have no clue why you would even consider putting that thing on your car. Not to mention all the chassis and engine codes they list in the title are for 4 cylinder cars (Integra and Civic).

Do yourself a favor, don't put cheap crap like that on your car. Spend the extra money and get the ATLP or XLR8 test pipe. Not to be rude or anything but when modifying a car don't do it for as cheap as possible. This stuff is expensive because it's worth it having a part that was built for your car from good quality materials.

I understand what you mean but I'm not buying wheels or a catback... a test pipe is just a piece of stainless steel straight piped... 125$ sounds a little too much for that. Any ebay stainless steel pipe that fits will do the job. Anyways if there's none I'll just get one from xlr8 or heeltoe. But if we can save some money here why not? :yum:

Since the test pipe on xlr8's website says that it also fits 03-07 Accords, maybe this one will fit the TL?

What are you looking to do it for? My understanding is that the 3rd cat isn't nearly as restrictive as the precats are when it comes to power gains. I doubt you'll find an ebay chinese made pre-cat. Believe me, I'd probably buy them if there were, since hard parts are hard parts, and you only really have to worry about them cracking. I've rarely kept a car long enough to worry about that though.

Unless your third cat is clogged up, a test pipe isn't going to do much. When I did my J-pipe, the third cat looked like it had 20k miles on it, not 145k miles. It was in superb shape and the interior design looks like it flows well.

IMO, it would be better to wait until you feel like spending $400-450 to get a J-pipe that also eliminates the third cat.
