Yeah i know someone might say nopi.com and ive already placed my order for it with them, and today i get an email from them saying that it is unavailable, plus since they deducted it out off my debit card they said, it would take 5-7 business days for my money to be back in my account GRRR... Does anyone know of another place??

I recently read this in an article on performance exhaust:


It makes sense to actually have a cat installed that's larger than the nominal pipe size. For example, a 3-inch cat on a 2.5-inch exhaust will give better results than a 2.5-inch cat on a 2.5-inch exhaust. Testing has even shown that expanding a 2.5-inch aftermarket cat's nipples to 3 inches results in a good improvement in flow. However, shallow angled cones should then be used to adapt one pipe size to the other, reducing the restriction across the transitions in pipe size.

I may try it when I get new exhaust piping. I'd be using a 3 in cat fitted to 2.5 in piping. It seems that with a setup like this, you can use a regular-flow cat but still get hi-flow results.

You can get a 3" inlet/outlet cat for $65 here (http://www.discountconverter.com/universals/index.htm). They also carry universal hi-flow cats for around $100.

PM me or AIM me.

site it looks like the hi-flow cats are cheaper than $100. Which hi flow one would we get though if we wanted to get a 2.5" cat to go with 2.25" piping?

I would click on their universal hi-flow cats page here (http://www.a-1performance.com/super_converter/super_converters.htm) and choose the 2.5" inlet/2.5" outlet design. It's model #15146 and it's $105.95.

Go with the ludespeed test pipe (more hp gain)

dont flame me if i am missing something, but wouldnt that result in even less backpressure?? oh well... i thought that was the reason it was pointless to do a headers pack straight exhaust, simply becuase we would have NO torque until we got the rpms up!

You mean "exhaust gas volocity",.....don't you,......hint hint:p

Well like I've said before, I looked into my cat-converter and it sure didn't look high flow to me. Now if and I mean 'if" everone's high flow cat design doesn't really look much different than my stock cat, I could see the strait up logic of the test pipe. But some on use to have regular emissions testing.

Hey Site, wouldn't using those two ideas together make the most difference? Buying a hi flow cat that's also about .25-.5 inches larger diameter than your piping would give you even more flow it seems.

i cut my cat out and put pipe there.......it gives your muffler a deeper sound and gave my car a little more get up but no much.

Well ill be getting 2.25" piping so wouldnt i go with the 2.25" cat?
or would getting 2 1/2" be better?
Well i just hope NOPI.com send me my money back soon so i can get this ordered....
