Topspeed pro 1 headers?

I searched and couldn't find anything about them really. They are located in Texas and I called them today seemed pretty easy to work with. I see a lot of people run their exhausts. Hard to go wrong for 370$ shipped and I'm wanting to delete my cats. Anyone have any info on them?

Topspeed headers are probably half of the ones people have bought off of Ebay. There's tons of information on them. They work, but there are better performing headers. The fitment can range from okay to terrible.

I finally found a few posts on them....I believe I'll just hold out for an actual brand.

S54 M3 stock OE exhaust manifolds actually Look like high performance headers, especially when compared to my M54 330Ci OE manifolds. Your cheap alternative would be to buy an inexpensive OE set on Ebay, then knock out the fragile Cat material, which will be very easy to do. What you'll have left is a set of perfect fitting free flowing headers that didn't cost much & make WHP.


I'd go this route if I wanted to save a buck,
