I just picked up my 95 GSR sedan from Magnaflow. They dynoed it before and after using a full stainless catback. Click the link for the sheet. As you can see there was a gain of 5hp and almost 5 lbs of torque. I'll have picks of the exhaust when it goes into production. I was told by the tech that idle was quiet and loud when on it. BTW it was run to 3rd gear.

Damn man it looks good

Looks like you picked up around 10 FT-LBS at 5200

 

cough thanks ryan cough

 

Are they making a new exhaust?..........i have a full-stainless steel cat-back exhaust from magnaflow..........i got it about 6 months ago..........this is the one i got

 

yep. That was what I was told. They needed a 4dr and 2door. BTW they're looking for a Celica GTS if anyone is interested. They'll give that person a free exhaust too.

 

where did you get your ehaust from? an what's the diameter?

 

not sure on the size of pipe. The muffler size is on the bottom of the dyno sheet.

This was done by Magnaflow's R&D dept. They wanted to fit and test a GSR for production. I'll have it on in a month and they'll also re dyno it with my AEM CAI! Not bad for free!

 

That worked out nice,see how that 95 produced pretty well on the dyno,stock with just an exhaust it pushed out 150HP and about 118lbs of tq.Pretty nice.

 

looks good

 

I don't believe you can get that much power from just an exhaust. Maybe it's because of OBD 1......

 

whats the biggie?

your bushing 25more whp with cams/c gears and bolt ons, must be the OBD-II ?

 

let's try this again.... I am only saying his car made some really good gains from just an exhaust. Most people are not so lucky. That is all!

 

It is OBDI. Also how often do you actually see people dyno just an exhaust? Not too often so its not really fair to assume that all these damn exhausts make like 2 whp, which is what a lot of people seem to think.

 

I dynoed my car when I all had was Comptech header and intake and I dynoed it again after installing the exhaust it only made 4 whp. That's from a $600 mods!!!

 

Go to this link and read this dyno plot that was done http://integra.vtec.net/carmag/importtuner1.html and you'll see a difference in years and how the 94 to 96 produce better dyno figures to the wheels with basic bolt ons.The 96 has OBD11 however it was revised in 98 and dyno figures sucked,96 gets about 15HP to the wheels from header/exaust combo and 98+ about 2.4HP from same combo!

sorry, but I do not agree with that article. Many OBD 2 GSR's on this board are making very good power (~160 whp) with just CAI,h,e. My car made 158 whp after CAI,h,e,adv timing. I was pretty happy.....
