I was researching and i found that the s-pipe gives about 4-8whp on the stock exhasut system. I was wondering if it is worth upgrading considering it is only $150. If i installed this on my stock exhaust system would the exhaust note be deeper? If any one has installed it can you please posta video or a review. And i am planning on buying the trd axle-back will the s-pipe make the trd axle-back sound raspy like when people have the AW header and TRD axle-back?

Thanx

 

In all honesty if u get just a spipe the gain will be minimal cuz its still going through the rest of the stock exhaust.

As for getting an s-pipe then a trd axle back (yes I said axle back) You will still need to get the mid pipe section...

I recommend Draxas or ZPI Exhaust... I think the draxas comes with the midpipe.

Check the link in my sig I sell the zpi product.
