The GP pricing is a little to low to post. Just give us a call or e-mail tbyrne@tbyrne.com for pricing.

The_Snyper

Are the cats in the catted y-pipe header package easily swapped out? Can straight race pipes be installed in place of the cats (similar to the FLP header system)? If so, does this package include them or are they available for sale?

Thanks

tbyrne

This package doesn't come with offroads but you might be able to have some made to replace the cats.

The_Snyper

Is it fairly easy to swap them out if I wanted to?

Black Z

Can you purchase the off-road pipes, like in the flp system, and they work on this system like the flp does to make it an off-road or a high flow pipe? Is the pipe used in the flp system to replace the cats the same size as this system?

tbyrne

iTrader: (15)

There aren't any offroads that can be purchased for this package. The Dynatech headers are stainless (some other companys use mild steel). They also use a 4 bolt connector to mate up the cats. Those cats flow very well -





Let me know if you have any other questions.

Tom

Thanks for the info.

Wildman

How's the ground clearance compared to like the SLP's. My car has been lowered and my SLP exhaust hangs really low. Do these tuck up better?

tbyrne

iTrader: (15)

These headers will tuck up closer than the SLPs so you will have more ground clearance.

The_Snyper

For my 98 T/A, what else would need to be purchased with this system? 02 extensions, etc.?

tbyrne

iTrader: (15)

The kit comes with everything you need for the install.

Apostle

I talked with Greg at Dynatech before I orderes mine about fit, installation issues and ground clearance. He told me they were identical to the FLPs due to the fact that they made the headers for FLP. Except these are stainless instead of ceramic coated.
