I'll give my support to
Summit Racing since the mid 80's, great customer service {usually get my parts within 2 days, even up here in the sticks, no extra shipping costs & sometime no shipping costs at all}... Also
Mancini Racing for all my Mopar Performance Parts & custom aluminum radiator {old Direct Connection} also never had a real issue with anything, that couldn't be quickly resolved, great guys even all the new guys, Dealing with them since the mid 70's when it was Ron Mancini that I would see at the track all the time... Also
Flowmasters, Scavenger Collectors, 50 series Delta race mufflers & mandrel bent 3" exhaust system out the back, great fitting, easy install, quality products & even better performance, even thou they are owned by B&M & others now, not the old original owner from Santa Rosa Ca. that I would see at the track all the time, that I used his products for near 40 years, still 100% USA Made in Sacramento Ca. now... Also
Schumacher Creative Services www.engine-swap.com out of Washington state, have great fitting Mopar Exhaust Headers & specialize in Mopar Engine swaps... Also
TTI Exhaust & Headers, pricey but fit great for street headers... Also

QA1, great reasonably priced & USA made product & customer support, they're retooling for many Mopar suspension parts currently thou, or were at-least the last time I checked....
