Hello all..this is my first post so bare with me...I have a 00 SE I have upgraded with an Injen COI and now I am thinking about adding a Warpspeed Y pipe and cat converter. I would like to know any feedback on this installation re: performance improvements etc., plus recommendations if there are any. I do not want a "loud" car so no ricer stuff for me. I have enjoyed reading the info out there from you all, hopefully I can add something to the group in the future. Thanks Tigger

 

I have a 2000 SE 5 speed (Cali-spec) and installed a Stillen Y-Pipe; the rest of the exhaust is stock. Fit was perfect and the only trick was to losen the bolts on the top of the front pre-cat to fit the pipe in place. The rear pre-cat is not used as it is on the old y-pipe.
The sound increase is a slightly deeper tone at idle and about 10-15 % more cabin noise while driving around town, but not a problem, not ricy. At 70mph the road and wind noise are louder than any exhaust noise increase. As for a performance increase, I noticed that from 4k-6k the engine pulls a little better than the stock y-pipe as the stock y-pipe seemed to choke the engine above 4k and limit performance. The performance increase was slight, but if you have a fed spec you might see a higher performance gain as the second precat is removed.

I'm not sure about the 00-01's but there are fitment issues with the 02-03 Warpspeed pipes. I would recommend looking at the other manufactures.

 

doesn't the ypipe improve performance pretty dramatically for the 3.0s?

 

.....check other places.

 

it should......

 

The best mods for the $$ short of boosting.

 

how do u likethe Injen CAI?? i was thinkin bout getting 1 soon??

 

Maybe since he bought the stillen one? The cattman gives a nice gain 10-15hp with an intake. If everything else is stock Brian Catts said 9-12hp.

 

how can you tell if your car is fed or cali spec'd??

 

I really noticed the difference, it seemed to make the car respond a little quicker and gives a nice "throaty" sound form the engine on acceleration. Not real loud like my son's Accura TL, just nice.

 

ok thanx alot i think ive made up my mind now

 

Count your O2 sensors (or O2 plugs on the front of the block) 4=cali

or look for NLEV on the front of the car = cali

 

i've got one, and i love it. response is quicker and the car pulls harder, not to mention the sweet song it sings. pick one up.

 

i have a Budget Performance y-pipe, and this thing smokes. my butt dyno noticed a pretty big difference. the car pulls very well! best bang for your buck
