Whats the difference between test pipes?
 

Are all test pipes pretty much the same? I was thinking about just getting a random brand on ebay. Or should I just get a well known brand at a higher price

You get what you pay for.. I'd check put fast intentions

Read up on the Motordyne Art pipes in the exhaust section

Rasp Think about once I've done some research

I really just want a pair of non-resonated ones, this is what I was looking at. Tell me what you think.

nope and nope

buy quality - avoid the headache

Yea i would stay far away from those... unless you want it to sound like you have 9 exhaust leaks...

Trusted name brand only.

I have GTM TP's. Couldn't ask for better quality. Never threw a SES before my tune. Yes there is rasp but who really gives a ......... It's not a big deal. Especially if your a real enthusiast.

I would agree, I have the invidia catless test pipes when driving normal sound loud but good but when I put it to the floor the exhaust screams like a race car and has a raspy sound but the performance is felt though.

Look for named brand hands down. You don't want leak, rust, SEL kickes in all the time. I would recommend Fast Intentions or Motordyne.

berk test pipes FTW....!!!

What kind of JDM test pipes are there?

Note sure there are any for the domestic market. But's there's plenty stateside to choose from.
