My son and I installed a complete kit from headers to tail pipes on his 2003 Pontiac GTP. Despite very tight underhood clearances, everything fit perfectly. It looks great and sounds great!

Quality Stuff!!!

Excellent parts and excellent customer service! Recently installed a short throw shifter and full exhaust from zzp on my SS. I couldn’t be more happy with the quality of the parts, and the excellent customer service answering all of the questions I had. 10/10 I recommend zzp over all other distributors for ecotec parts. Absolutely blown away!

Everything came as promised only two issues I ran into was the amount of room given for the wiring of the mass air flow sensor wiring and with the 2017 and newer the pcv vent tube to the intake tube has a connection that requires special tools(two pieces of bent metal ) but with out them it’s not the easiest process getting that hose off with out destroying it would be helpful to verify year and provide the two little tools needed for ease of install but other than that looks good and sounds killer if you want to hear your turbo spool and wastegate open this is the system you want

great product for the price, worth every penny, and couldnt be happier with my purchase. My SS has a deeper voice when its idled and you can noticeably feel the HP gains at higher rpms.

Overall, I'm very happy with the products, quality and customer service along with tech assistance. Thank you

Steve has been excellent, Only compliant I have is UPS screws Canadian customers by charging 40 dollars to be broker no matter what you buy. I know if I need something in a hurry you will over night DHL. Thanks for great service and products. 7/8 chain will not hold my power. I spit them out in 7 passes Schattered chain and broke a tooth out of a gear. Rumor has it that there is somebody building 1 inch chain Think you guys need to lead this as you lead most 3800 stuff Thanks John

A1 shipping, A1 quality, easy install

In the past 8 months I've bought a great amount of aftermarket and replacement parts From ZZPerformance. Downpipe, powerlog, HV3 insert, gaskets, 1.9 rockers to name a few and all have been exceptional quality! But it doesnt stop there. Shipping is always quick and on time (sometimes a day early) and costumer service is amazing! The one time I've had to call, they were informative and incredibly helpful. ZZPerformance is a 5 star company that produces 10 star results.

Ryan has been most helpful as I stumbled around figuring out the whole process. I received a RMA from Ryan, shipped back the red LNF coil packs, bought OEM coil packs in place of the red ones and finally figured out where the in store credit was sitting with help from Ryan. I used the credit when I bought the LNF Stage 1 cams. Once the autox season ends these cams will replace the Stage 2 cams. I sent Ryan a link to the 5 part blog about the building of the SCCA Solo E Modified "Jeep" so take a look and enjoy.

The products I have purchased are amazing!! My only complaint is when you guys are out of stock on an item it takes you guys forever to restock. I’ve been wanting that HHR full exhaust for awhile now and it’s always out of stock 😐

Really nice to have a store dedicated to the 3800 engine with great performance parts only found here. Having a knowledgeable and experienced staff to answer any and all questions is a giant plus. I feel lucky and thankful to have found this store to help me build my dream engine. My only hope is that you get some of the items that are out of stock and possibly come up with some performance items for the series 1 but overall great store. Keep up the good work, thanks.

Fast shipping, product as described

packaging was the best i have seen. when i put all the pieces together i was amased how good it looked .and it sounded better.
