Spoke to a rep on the support line who suggested to replace the oem manifold with an opel one from zzp for $80 Gm replacement manifold in Canada is $ 700 I will definately recommend and use zzp

ZZP has performance products that work. With their simple bolt on mods & remote tunning, my Cadillac ATS 2.0T LTG went from a stock 14 second car to a 12 second beast down the 1/4 mile. Their customer support is outstanding and knowledgeable - something other companies can’t offer. Keep up the great work guys!

I’m very happy with the ease of installation and the noticeable increase in performance from your stage 1kit and strut tower brace. I look forward to installing the stage 2 kit and hopefully forged rods pistons cams springs upgraded turbo arp head studs and more. I’d love to represent ZZP on the east coast Boston metro area by attending shows and showing off the performance upgrades from ZZP. Unfortunately it looks like a lot of the products after the stage 2 kit are out of stock keep me informed as to when they’re in stock again. Maybe a discount/sponsorship for representing ZZP out east would be amazing 😉. Thanks I look forward to buying more of your products in the future!!

I have been purchasing all the necessary parts to swap to Gen 5 for my 1999 Buick Regal GSE Not only I am impressed with all the parts that are available, I love how fast the parts arrive at my door step. Living in Canada finding high performance parts for 3800 are impossible. Thanks to you guys at ZZPerformance I am able to modify my car. Looking forward to putting in more orders as I modify my transmission. Sirous

Had a couple questions about products and the best way to do my build.... The anwsered everything i needed quickly and didnt push anything on me. I eventually order 3 different things. They got to me quickly and were package nicely. Everything with ZZP is great, will use them over and over
