I have a 2000ss with gmmg cat-back exhaust i am looking to put headers high-flow cats and y-pipe on my car and im wondering if i should get long tube headers like flp with everything or something like mac shorties and a y-pipe with high flow cats MTI is going to be installing my headers so please put your comments in, thanks alot

 

Shorties are not worth the time. Go for a set of long tubes.

 

if you dont have to deal with emissions LT's all the way and dont look back

 

if you do decide to go with shorties however, get the BBK's, they are 1-3/4 like the LT's, all of the other shorties are 1-5/8

 

Forget shorties. Go for Mac midlengths or Long tubes. Like Wilwaxu said, don't waste your time with shorties.

 

I received my Pacesetter long tubes today and they look great. For the price of these, you wouldn't be disappointed. Probably cheaper than most shorties.

 

LONG TUBES SHORTIES WERE RECENTLY POSTED IN GM HIGH TECH AS ONE OF THE 15 MISTAKES TO MAKE ON A LS1 ESPICALLY IF YOUR AN 00-02

 

If i get the pacesetter headers what y-pipe and high flow cats will fit that because some say like bassani's y-pipe only fits bassanis headers what system will fit pacesetters

 

pacesetters have their own y-pipe that fit right to it

 

If you want to spend some extra money I would go with the FLP's, they come with ORP's and cats, so you can switch with the clamps...also comes with a Y-pipe....

 

mustang owners buy shorties ..LS1s like long tube

 

LT's and don't look back. FLP or Thunder Racing. Pacesetters are a great deal for the money, but remember you get what you pay for. Drop your emissions while you're at it! !EGR, !AIR, and hollowed out cats.

 

My vote goes for the LT. BTW, I have not seen any dyno proof that shows ANY difference in the FLP, Thunder, QTP over the Pacesetters.

FWIW, in my opinion, the Eldebrock headers are the best bang for the buck, especially on a H&C car, or any car using nitrous. $$ is close to the Pacesetters. Stepped header, that also comes with a Merged 3.5" race collector!

I just bought a pair for my car & will test them over the Grotts (same as Thunder & QTP).

Stay away from SLP. Way overpriced. One thing for sure is that headers are going to get banged up, they are going to get scratched up, they are going to loose their coating, over time. If performance is similar, why would anyone spend hundreds more?

Also, when you compare what one person gains over another header, ask if they took AF readings, & if they compared gains/losses by "adjusted" AF readings. This should be all that you are concerned with. My .02.
