Hello everyone. I have been searching throughout this site trying to find the answer to my questions, but I can't seem to find the right answers

First I plan on buying an injen cai and an axle-back exhaust from precisionmuffler.

Now my question is what kind of effects will installing an s-pipe have on the car? As far as added horsepower and will it affect the sound of the exhaust? If so how?

Thanks a lot!

it did on my exhaust...but i believe i have a small leak around my second resonator....

its not a bad change...makes it a little louder, but not raspy...

as for HP gains, minimal, but with a full-catback, it can help

 

to make it a full cat-back, all thats missing is the mid-pipe right?

 

Oh and what are the hp gain claims for the axle-back from precision muffler?

 

unsure....axle-backs have little gains...cat-back(like my meagn..sorry, i like it) have better gains...now an s-pipe,miod pipe and axleback, should net you a good, 10 hp max i'd say?

jsut a guess...im not sure

 

if you have the hks axle back exaust what would i need to make it catback? midpipe and spipe? or a high flow cat?

 

adding a midpipe would make it a catback. the megan midpipe actually deletes the secondary cat.

 

alright cool thanks for the info

 

so basically if I just plan on getting an axle-back exhaust, then it wouldn't be worth buying an s-pipe right?

 

not true, stock spipe is very restrictive

 

spipe and primary cats are the most restrictive part of your exhaust system and this is were you will see the most gain.

but if you plan on doing an s-pipe I recomend a cat back or mid pipe with your axle back to take advantage of these gains.

 

yeah stock s-pipe has a pretty big pinch in it...

 

Tha axle back alone on your stock tC will give you 2HP gain. Anything else added on will just help with the HP gain.

 

I do not plan on getting a header for my car, so what effects woudl the s-pipe and mid-pipe have on the sound of the exhaust?
I am debating between greddy sp2 and pm axle-back.

 

go with megan! here's mine:

the s-pipe makes it a little louder...might possibly add rasp, but its not super likely

 

nice brian that sounds sweet i hope my hks sounds like that when i get the spipe and midpipe

 

The midpipe will make it much louder and raspy... the spipe won't effect tone much at all...

It's due to the removal of the second cat and resonator in the midpipe... I suggest waiting on stock midpipe removal unless you go F/I

 

mine did not sound any different when i put it on.

 

cool, thanks guys.
