From pypes yes, I've dealt with their parent company Performance Years before that

Was it easy to install? Any installation tips that will help others?

Very easy to install. A lift would be nice compared to working with the car on jackstands in your driveway

Once you've had a chance to use the product, did it meet your expectations?

What made you choose this particular product?

Being an autocross car, I wanted the most midrange torque possible, which the Pypes headers should help build with their stepped tube design.

Is this your first time buying from this brand? Did you consider other brands?

Considered BBK and Kooks but went with Pypes because of their all stainless construction and the price.

What made you choose this particular product?

X pipe came with my cat back system, which for the price was the best option.

Is this your first time buying from this brand? Did you consider other brands?

Would have loved a BBK system, but the price was way too high

Was it easy to install? Any installation tips that will help others?

Down pipe bolts from the manifolds tend to snap if you don't add heat to remove them.

Once you've had a chance to use the product, did it meet your expectations?

Probably the best value.

What made you choose this particular product?

Wanted something with more rumble. Got rid of the mufflers for resonators but still wanted some more. Warning it is LOUD.

Is this your first time buying from this brand? Did you consider other brands?

I’ve had Pypes brand exhaust on this car and a V6 that I had before and I have no complaints. Great quality, welds are great looks like a good stack of dimes.

Was it easy to install? Any installation tips that will help others?

Installed it myself. Wasn’t too bad can get it done with jack and jack stands in the driveway like I did but would prefer a lift. To get the bolts out where it bolts up to the headers were sort of tricky on the one side. Going to need an extension that rotates.

Once you've had a chance to use the product, did it meet your expectations?

Sound was amazing. When you delete the cats you have to expect a lot of rasp especially with my setup. I set off alarms in parking garages sometimes and have set off a few cars as well.

Any additional comments?

If you have any questions about install or sounds send me a message I could help ya out with some advice or maybe even some videos.
