Default borla

I am wondering how many HP I can expect from putting on a Borla exhaust on my 1998 1.8T. It already has a neuspeed chip. The AWE website says it adds 15hp does that sound about right? How turbo noise, does that increase also? I love that spool up sound.

Default from what i've read, you can expect probably anywhere from 5hp-15hp increase.

i think the 15hp claim is a little on the high side, and i think that would be with a chip pushing more boost than a neuspeed chip.

you'll get a deeper/louder exhaust sound, but i wouldn't expect the turbo spool to be any louder.

Default the exhaust does increase both hp and turbo spool up,

which reduces turbo lag. Not certain about 15hp, probably more like 10. The sound is nice and throaty roar.

Default On mine (APR chip), very small hp increase...

10 hp might be generous but that's on a butt-dyno only. turbo whine is also ever so slightly increased. overall exhaust sound however is noticably different, and I do like mine quite a bit. not too loud but a growly-er pitch.
