Greetings,

FYI: GS Motorsports is having a sale on Exhaust Systems, Headers, Cat Backs & High Flow Cats for the 6.1's and the 5.7's, now through the end of April. Sale pricing will be honored for all exhaust systems ordered by forum members through the end of April. Discounts apply to installations too.

If you are considering other mods, ask about a package deal.

Call GSM at (562) 777-1075 and speak with Tamara or Dan.


BTW: Irwindale runs Thursday nights 4-10pm. Last week I only managed a 1.89 60' (on street tires) and a 8.1 1/8 mile ET. This week I think I'll run my new Nitto 20" Drag Radials instead:biggrin:

Update

Maistro, I don't claim HP gains. Yes, the bigger pipes will let her breathe easier. Mine got faster with MF cat backs, and I did see 10rwhp with the MF Hi Flow Cats (took em off and lost 10, out em on and gained 10 again).

Brute: No, no pics of the Nitto's, sorry.

Eric G: I'll be happy to deliver to Ohio for ya!
