If you haven’t followed this blog, for Project Trans Am I decided on the Pypes brand header back X exhaust system. One of the finishing touches is to add dual chrome exhaust tips. This dual tip look was used from 1967-1969 and from 1976-1981. It is one of the subtle but unique details for any late model Trans Am of the era.
Originally I purchased a set of EVT10 Pypes exhaust splitter tips (retail for $75-$100) to connect to the splitter adapter kit TGF10E to convert my Pypes X pipe kit from a Camaro exhaust system to a Firebird Trans Am exhaust system. Though the web site advertises these to have a 2-1/4″ exit tips, the tips are actually both 2-1/2″ in diameter. The extra wide tips make it harder for them to tuck under without hitting either the rear leaf spring or the body. On top of this, the band clamps they came with are not strong enough to clamp the stainless steel. I then decided to try drilling a hole in the tips to try to use a screw to hold them to the exhaust pipe without any luck. Basically, the stainless steel used is so strong, the only way to attach these tips is to weld them on.
In addition to the problems with the tips, the TGF10E kit did not fit well with the piping portion that bridges the mufflers to just over the axles. Modification was necessary in order to get these pipes from the kit to fit without rubbing against the under body. I will still have to take my car to a muffler shop to tweak the pipes over the axles if they don’t settle away from the under body this Spring.
I decided to order a pair of the 35218 Mangnaflow exhaust tips (retail for about $125-$140) after seeing them in a previous episode of Detroit Muscle (TV show from the folks of PowerBlock TV and Muscle Car). Two days later (they came fast) I had them in my hand and I was impressed. These actually have an inlet of 2.5″ and outlet tips of 2.25″. They are also polished stainless steel. They have a straighter profile so you can tuck the tips under the car better. There are 4 relief cuts made along the collar so they can be clamped on easily. They look more like factory tips than the Pypes tips.
With all the problems I’ve had with the Pypes system from the mufflers back, if I had to order an exhaust system today, I would buy just X pipe portion and downpipes from Pypes, Texas Trans Am or Magnaflow mufflers, then Magnaflow muffler back exhaust piping and tips. I wonder if it’s even possible to buy such a combination of brands?
