Customer Reviews
Consistent quality, returning again
This was my third order from GSTP Auto Parts. I needed a new Braided Fuel Line and a Fuel Filter. Just like my previous purchases, everything arrived as expected. The parts fit perfectly, and the quality is consistent. Their AN Swivel Hose Ends are always reliable. I keep coming back because I know what I'm getting. Delivery took about a week, which is pretty standard for them.
My Exhaust Pipe is awesome!
Got an Exhaust Pipe for my project and it's fantastic! The sound is just what I wanted. It arrived so quickly too. Definitely shopping here again!
Solid Intercooler Pipe, detailed review
I recently purchased an Intercooler Pipe and a pair of Silicone Couplers from GSTP Auto Parts. The ordering process on their website was smooth; I found what I needed easily. Shipping took 7 days to reach my address in Texas, which was acceptable. The Intercooler Pipe arrived well-packaged, no dents or scratches, and the welds looked good. The Silicone Couplers felt durable and had good flexibility. I had a quick question about compatibility before ordering and used their online chat, which was surprisingly responsive, answering within a few minutes. Installation of the pipe was pretty standard for an aftermarket part, everything lined up. I appreciated that the product photos on the site were accurate to what I received. Overall, a good experience and I'd consider them again for future upgrades.
Good parts, slow shipping
I ordered an Oil Catch Can from GSTP. The product itself was solid, seemed well-made for the price. Installation was straightforward enough. However, it took almost 9 days to get to me in Florida, which felt a bit long. I wish shipping was faster.

I need a new intercooler pipe and some silicone couplers. Are the couplers universal or do they fit specific pipe sizes?
Hey guys, thinking of grabbing some braided fuel lines and an AN swivel kit from here. How long does shipping usually take to California?
Can you use more than one coupon code at checkout? Like if I have a free shipping code and a percentage off code?
Planning a big order for a full exhaust system and some fuel components. Do they have any kind of first order discount or a newsletter signup bonus?
Does anyone know if their oil catch cans are truly universal? Or do they need specific mounting brackets for different cars?
