Cant be beat!

I was very skeptical towards buying this or saving up to buy the first exhaust i fell in love with (corsa) why? because most videos (actually all the ones i saw) about it didnt make it seem loud enough for me, i wanted something with a deep rumble, and have a bit of race raspyness. This is a great buy for what you pay for, its a significant improvement over stock. the rumble is there and its not annoying loud, it tops out at 4k rpm after that its more motor than anything. love the titanium tips too WD40 helps clean and remove grime fyi.

Quality product and service!

I got my invidia n1 really quick from rally sport direct. It took me under 2 hours to remove the old SPT exhaust and install the n1. It could've been done quicker but the old exhaust had some very old nuts and bolts that were a pain! Only downside I have to this exhaust is that I wish it were a little louder. Its barely louder than my previous exhaust which is the exhaust that was on my car when I bought it (I believe mine was a factory upgrade exhaust, but not sure). The n1 is still sexy though and it has a good sound!

Amazing But be careful!

This is a quality exhaust. Absolutely amazing, Im running a stock DP with this cat back and even then it definitely brings out the life in this car. Only negative thing, is that there was no bolts that would fit the dp connection out of the box, so to those who still have the stock DP, You'll want to get the Grimmspeed stock downpipe adapter (part # GRM 077046) otherwise you run the risk of exhaust leaks where the connection is at, an extra $30 but its well worth it with all the trouble it'll save you in the future! Other than that it's perfect!

Bolted this catback on within 2 hours, everything fit perfectly with no hiccups. Sound is excellent, obviously highlights the bassy rumble. Fit on, drove for 2 weeks and stayed solid on a 500 mile roadtrip to California with no incident. Only issue I could even kind of say I have is that there is a bit of drone on the freeway over 65.

Beautiful Hardware

Yes, it's loud. It's a performance cat back. I haven't used the dampeners at all, even with a baby in my back seat. She loves it and hums to it. It's deep and throaty. Certainly not for those who for some reason want silent horsepower. Running full divorced DP etc. and it REALLY helped eliminate bottle neck/cel from over boost. Now I hit 20 psi without range-ing my solenoid. Absolutely a necessity for any modified engine.

  • Q: Size.   Xavier 3 months ago


    Is the tip that bolts up to the downpipe 2" or 3"?

    • A: The flange will be a 3 inch 2 bolt at the downpipe connection.

  • Q: Hardware  kurtrusselle 3 months ago


    I saw that it includes 8 bolts with gaskets. I was wondering what are the sizes of the bolts?

    • A: This exhaust system will come with quantity 6 of M10 x 1.25 Bolt & Nuts and then the two catback to downpipe bolts, I am unsure on the size of these.

  • Q: N1  Nate 3 months ago


    Would this take little to no modifications to fit a N/A forester? The hangers and dimensions seem identical.

    • A: This is not a confirmed fit and would likely need to be cut and welded to work on a non turbo forester.

    Do I need a tune on a 08 wrx?

    • A: No this exhaust does not require a tune.
