Mine showed up about a week ago. I am waiting on a new motor and a downpipe and I will post results. The systems looks really well made and well worth the money...
Pypes STAINLESS Exhaust System..

Cool....I have mine on order. Thanks:smile:
How about resonance ? I have a drone at 45 to 55 mph that drives my wife nuts... Looks good !!
Hey my car had the rear cat flange removed. The ( shell ) is there but the pipe was welded to it ? I wonder if I could some how make this work or would I have to get a new Cat as well ? The pipes split with a y looking piece to 2.5 pipes and magnaflow straight through mufflers sounds good at idle and wot ...just as a drone. Will the pypes be better ?

Really? Where did you purchase the tips from? Any pictures?
Should have everything installed next weekend so I'll take some video as well. I agree, just cant beat the deal for what you get:smile:

I used to work in a rifle barrel manufacture and found info on 409 ss....its not to bad.I would of grabbed this exhaust to but had already ordered the hooker catback...but sold the mufflers and put 2 dynamax race bullets on..this is a good deal.

Corrosion Resistance
Grade 409 resists atmospheric and exhaust gas corrosion. A light surface rust will form in most atmospheres; this rust retards further corrosion but makes the surface undesirable for decorative applications. The corrosion resistance is about the same as that of 3CR12 and the 12% chromium martensitic grades such as 410, and inferior to the 17% chromium grade 430.
Heat Resistance
Generally 409 is classified as resistant to scaling in intermittent service up to 815°C and up to 675°C in continuous service, but these temperatures are dependent upon the exact service environment.
Heat Treatment
Annealing - heat to 790-900°C and air cool. This grade cannot be hardened by thermal treatment.
Welding
Readily welded but a pre-heat of 150-260°C is recommended. Grade 409 or Grade 430 electrode or filler rods can be used, but AS 1554.6 pre-qualifies welding of 409 with Grade 309 rods or electrodes. These austenitic fillers result in a more ductile weld.
Post-weld annealing at 760-815°C improves weld ductility.
Post-weld annealing is not required when welding thin sections. Automotive exhaust tubing is typically welded without filler metal (autogenously).
All welding must be carried out with minimum heat input to reduce grain growth effects.
Applications
Typical applications include:
· Automotive exhaust systems
· Catalytic converters
· Mufflers

Nice! I'll be ordering some of those tips soon and thanks for the pictures.
Did a little polishing on the mufflers today....

In the second (right) picture...the "Y" pipe coming out of the catalytic converter is coming from the left side of the car...
Maybe it's just the picture that's reversed or the system was put together wrong... Claude :wink:
