I recently bought test pipes for my HR and I have heard that I should not utilize the mounts because of cracks on the welds in the long run. Any truth to this?

Here's the direct quote from the website I bought them from.

"These test pipes have mounting brackets just like stock but we suggest not using the brackets. The brackets cause the exhaust system to become to ridged and over time this will lead to cracking at the weld between the bracket and the race pipe."

 

try doing a search, i know there is a thread on this.

 

Well this is confusing. Test pipes with mounting brackets, but the manufacture suggests not using the brackets. Umm...so why are the on the pipes?

 

because they just used one of the designs everyone else does and rebranded them lol

 

testpipes are FTL. you should only be using testpipes if your going to be testing them for dyno or track use man. other than that its just gonna make your engine run RICH and overtime ruin the cylinder walls ! sell them save up some cash. get some HFC

 

30,566 miles on test pipes with mounting brackets. Still in one piece. Knock on wood.

 

Thanks for the input everyone.

 

What?

You don't really believe that, do you?

 

Does anyone have a DIY for test pipes? I searched with no luck.

 

Proof needed.

 

idk i had tps for about 4k miles until today i swapped them out for hfc's to pass emissions in north carolina but mine didnt have brackets and i didnt have a single problem with them nor did i experience any check engine lights. like always stated with tp's there will be a smell but its not that big of a deal

 

Im used to the smell, I ran cat-less on my STI. Im really interested in finding a DIY now.

 

wha wha what?

as far as a DIY....really nothing to it. Go under the car and look at the stock cats, and you'll see if you feel like doing it yourself. Not hard at all, but you need proper extensions, etc. If they are halfway decent, they will be a direct swap. The fact that they have brackets that they tell you not to use is lame...because those brackets are now going to knock against the chassis of the car without being bolted to it.

 

Thanks for the info Z1, I just got them in and I realized that I actually got the newer Turbo XS testpipes that have no brackets!

 

After raising the car on a lift, I was baffled on how to get the top bolt on the left (if your facing the car) cat off. I used a swivel on a 24inch extension and still couldn't get it without slipping off the nut...no homo.
