Hey guys I have a 98 maxima se(auto),and I have a PR cai,and soon to be installed,racing straight pipe from maxima.com ,budget Y pipe,OBX catback exasust.How much more power will I get when I have all of these in my car?est.(horse power)Also do you think it would be to loud.I would like to know some estimets on the total horse power I will get.And what My car would do in the 1/4 mile and 0 to 60 ,compared to stock. Thanks any input would help

 

It will be loud as hell. Don't expect more than 25 hp at the wheels. 1/4 mile, mid to low 15's at best. Auto sucks. I'm auto too. I hate it.

 

Well I think it souldn't be to loud because the racingpipe is resonated,also the Obx catback has 2 resonators and people say the obx is not to loud.Oh well I'll find out when I install them all.I hope Its not to loud.Any one here have a setup similer like this?If you do how loud is it? 25 hp hmm.. I thought just the pr intake and y pipe would make that,how much more with the racingpipe and catback?

 

25 more or less. I think the range is like anywhere from 20-35hp denpending on your vehicle and system.

 

i dont know diddly about auto's, but i would think that he might hit 14s with that setup...

 

WoW if I were able to hit 14s with this setup I would be happy,but I"ll have to wait till this weekend to install everything on the car.My car only has 61,000 miles so I think it sould be pretty fast with this setup, not as fast as a 5 speed

 

Thats the setup I have, and I will be dynoing this sunday. look for my post later in the week.

PRCAI
BUDGET Y
RT CAT
WARPSPEED B
HKS MUFFLER


After PRCAI and YPIPE, there was nice power gain, of course.
After the RT cat and the catback, there was also a nice power gain. Catbacks do really add some power for the 4th gens. For me, my OEM cat had 130k miles on it, so that might have had something to do with it too.

 

Look in the dyno forum. There are dynoes of autos with similar setups.

BTW, I got 171.x HP and 184.x TQ with similar mods on my 97 auto, which as ppl have already said equals an increase of ~25hp/25tq at the crank (considering a 20% drivetrain loss).
