how much rwhp will switch from stock to magnaflow give me aprox?

 

under 10rwhp

 

You'll probably be at 260-270 hp w/ a magnaflow added to the equation of your current mods.

from stock to a magnaflow about 10 hp sounds realistic.

 

^ YEah, but the sound difference will make it worth it as well as the gains!!

 

Yes, the sound is waaay better than stock.

 

I had to add a cutout as well to make a sound difference for me. Gains of around 10hp sounds realistic though.

 

yeah thats what i was thinking. some people at speed shops claim 20 hp to the wheel i am like thats alot sounds like your trying to sell me a exhaust. but maybe he meant with the long tube hooker headers i was looking at too . those and the magnaflow will make it sound real nice and i could see 20rwhp with both dont you think?

 

Yeah, 20 at the wheels with just a catback sounds high, with headers though it is definitely obtainable, and some.

 

i was also looking at borla exhausts will that add anymore..

 

The gains will probably be similar, with the better flowing catbacks, the gains will not be too out of line with each other.

 

realistically a borla should be more than a magnaflow, as long as you don't have any plates in, it's basically a cutout. I'd probably say a borla should give you 3-5hp more than all the other catbacks with no plates.

I use to not care much for borla's labeling them as overrated, but since the borla was added to our Grand-Am GT H.O. I swear by them. tips are a little ugly, but sound and hp gain was pretty damn good.

 

sorry to be the one to make an objection but didnt the 93 z's come with 275 horses? so wouldnt it be more like 280 to 290???

 

275 flywheel horse power. He's saying 260-270rwhp with his current mods plus the magnaflow.

 

i just put a magnaflow on my 98 it sounds great.... i cant say enough. and there was a definite improvment i put on part number 16723 with quad tips.
