Please read before you buy
Tailpipes are built in 2". We can go to 2-1/4" max, with no fitment guarantee. 2-1/2" will not fit and we do not build 3".
We build to OEM exhaust-manifold specifications. Fitment to aftermarket headers is not guaranteed - message us with your collector outlet diameter.
We do not build catalytic converters, X-pipes, side-exit systems, mandrel bends, or headers.
Questions about fitment?
Send us a message through eBay with your year, make, model and engine and we will confirm the exact kit before you order. We answer every message.
