If you are looking for a great way to squeeze a little extra performance from your vehicle, then you will be pleased with the Invidia Q300 Cat Back Exhaust System. There are several performance attributes that makes this an excellent upgrade. This exhaust system has been made from 304 stainless steel and features between 60 to 76MM piping. The exhaust has also been designed with minimal bends to reduce the amount of turbulence during acceleration, allowing the engine to exhale the exhaust gasses with less restrictions. This means you will have improvements in throttle response, along with increases in both horsepower and torque. 

This exhaust will come with a pair of beautiful 60MM polished tips, and the exhaust hangers are welded onto the stock location of the pipes so you don't have to perform further modifications.

 New gaskets and hardware will be included to make this exhaust system ready for installation.

In Love All Over Again
Wesley B 2 years ago
I purchased my Legacy GT wagon last August. It was well worn and needed some love to get it road worthy again. The previous owner had an aftermarket exhaust system on it (don't know what brand), but removed it with the sale, replacing it with a stock system. It was disgustingly ugly and way too quiet. Anyway, I agonized over what system to go with. I wanted a sporty sound, but nothing that was obnoxiously loud and raspy. I chose the Invidia Q300 after a friend recommended it to me, since he had the system installed on his STI. i voiced my concerns and he assured me I'd be ok with the Invidia. Well the bottom line is, I couldn't be happier. Great sound, great looks, great price and a lot of compliments. The ground clearance is tight where the piping routes around the rear suspension and differential, so have to drive carefully on rough roads with a lowered car. Otherwise all smiles. Will try to upload a Video/Audio clip in the near future

There's not much else to say. Sounds great on my 2007 Legacy GT. A quality product.

Overall a very impressive product. Happy I went with it rather than the alternatives. Only negatives I have to add were there was no way to use the Grimmspeed stock downpipe>3" catback which is suggested on this site. It spaced the whole system out enough that the mufflers would make contact with the end of the stock muffler cutout space so couldn't be used Also there does not seem to be a way for the flex section to not make contact with the driveshaft support mount even with the heatshield removed. An aftermarket downpipe that hangs mildly lower would be the only solution for this.

    I love invidia exhausts but would much rather a n1. Is it possible to swap the tips for the n1 versions - since I have a 05 legacy gt and this is the direct fit

    • A: It is not possible to replace the muffler tips unless you were to cut and weld custom tips on.
