Frequently Asked Questions

Do I need new fasteners to install this gasket?

The header bolts typically stay in place — you're only replacing the gasket between them. Check your bolts for damage before reinstalling; if they look worn or won't tighten down evenly, swap them out at the same time.

Should I clean the header sealing surface before installation?

Yes. Remove all old gasket material and carbon from both the header and cylinder head with a gasket scraper. A clean, flat surface is what stops exhaust leaks — don't skip this step.

What should I tighten the header bolts to?

Refer to your vehicle service manual for torque specs and tightening sequence. Uneven tension or wrong torque will cause gasket failure and exhaust leaks.

Came based on a work buddies recommendation. I was late by 30 minutes, confused my appointment time. But, 10/10 would come back. Came for a Downpipe and midpipe install. Not only was the gentleman accommodating, He ran into some issues, staff helped me out and pointed me into the right direction and got me going! They got my business and wouldn’t go anywhere else again!

Absolutely love the customer service that you get with Speedzone Performance! All my questions are always answered in such a timely manner and this a big PLUS because I live out of Florida and for them to be on top of answering all my questions in such a way means a lot. Thank you all for the amazing customer service.

My favorite place to go for anything car related, they have anything you could imagine & more. The people who work here are the coolest and most helpful people I’ve yet to meet at a car shop. They also don’t try to force sales on you and they genuinely help you with what you’re looking for, 100/10 shop!
