Hi All,

Not trying to start any type of altercation like my last post. Just want to know some general difference between exhaust terms. This is what I know from my previous car. I removed the cat which gave me about 13hp on my altima, with only a slight increase in sound at Idle. The replacement product was called a downpipe, race pipe, or test pipe. With the replacement of this part, my car could still passed emissions with flying colors because there are 3 cats before the last cat, in the headers.

1. Is the Midpipe where the cat is located in the '8?'
2. How much more power is produced? (from what I read, anywhere from 5-10 hp.
3. How much sound will be produced? Now, I know that sound is relative, but in your best description.
4. Would this pass emission?
5. Anyone who has previously done this mod please give me your experience, and anyone who would not do this mod for whatever reason please tell me why.

ALSO, I usually get someone that say do a search, don't wast my time. Just to let the members know, I did a detailed search so don't waste my time and say do a search.

Thanks, Buck

 

1. Is the Midpipe where the cat is located in the '8?' ---Yes
2. How much more power is produced? (from what I read, anywhere from 5-10 hp. --- From what I've read that seems about right.
3. How much sound will be produced? Now, I know that sound is relative, but in your best description. --- Again from what I've read its a little louder than stock, but not as loud as adding a catback.
4. Would this pass emission? ---Don't worry...no emissions in Florida (Don't know if it will pass in other states).
5. Anyone who has previously done this mod please give me your experience, and anyone who would not do this mod for whatever reason please tell me why. --- Only reason I can think of not doing it would be because it would make my 8 too loud with my catback.

 

try search>? jk! (come on I had too)
