is it ok to replace the oem cat converter with test pipe / hallow pipe...
not talking about the performance wise.but just worry about is it going to
be too loud? it is for a eg hatch
anyone running the test pipe?
thanks

 

it'll be louder, but with a test pipe and full exhaust, it should be resonable

it will sound more raspy though

 

I have a test pipe on my EG. It is loud. Mostly at WOT though. But when V-tec hits, its gonna be loud anyway

it'll be loud, a waste of money, and little to no power gain. if you have to replace your cat, atleast get a less restictive one. it'll allow more flow like a test pipe would, but it'll be alot more quiet.

 

You live in California. It's not worth the risk to put a test pipe in. Studies have shown that between a high-flow legal cat, and a non street legal test pipe, the test pipe only yielded like 1 ft/lb of torque more than the high flow cat. The only difference between a high flow cat and a test pipe to me, is the legality of it, and I would suggest you go with the legal one.

 

I didn't buy mine. Just holloowed out my cat. And it was noticeable

 

I have done the same on my b16 hatch and it felt like it was hurting it more than anything.

it was. our small engines need back pressure, if we remove to much of it, we lose power.

 

I did it to my B18C5 that has 12/1 comp. And it definately didnt lose any power cause of it.

Well, there's your problem.

 

Where's the prob? haha

 

You should get a bump inm performance 1 - 2 WHP maybe, it will sound a bit raspy @ 3k too.

 

the raspiness and the attention the annoyingly loud exhaust draws from the wrong people (the police) are not worth it, plus like someone said before me you're gonna lose a little low end power, which can't be afforded haha

 

hey dont worry about our ozone layer, we will be dead way before it affects us.

ITS ILLEGAL FOR A REASON
