Silenced Cat Replacement Pipe S1
Two Sizes Available 4" and 5"
Made to the highest standards from high quality stainless steel throughout. Argon gas "back purged" welds for smooth gas flow and high strength.
A must for the trackday enthusiasts that want the most from their engines without compromising sound (dB) levels.
The lightest available, ours is the only one proven not to reduce horsepower whilst giving you the benefit of a decrease in dB levels.
As stainless steel is used, we can reduce the flange thickness from 10mm to 8mm which keeps it lightweight too (less than 3 KG).
On one test it actually increased the horsepower / torque.
This 4" silenced cat replacement pipe is recommended if you need to reduce the dB level substantially but have a very large silencer already fitted.
If yours is a smaller aftermarket or original Silencer then you could use the even larger 5" Silenced Cat replacement pipe to reduce dB levels even further.
All cars produced from 1993 require a catalytic converter for MOT / road use legislations.
Can be supplied with our FULL Stainless Steel Fitting Kit below
Comprises:
2 x New Steel Gaskets
6 x Stainless Steel M10 Bolts
12 x Stainless Steel Washers
6 x M10 Stainless Steel Full Nuts
BEFORE ORDERING THE 5" VERSION PLEASE MAKE SURE YOU HAVE THE SPACE TO INSTALL AS SOME SILENCERS MAY BE TOO LARGE.
This fits the following models:
- S1 K SERIES ELISE
- S1 EXIGE & MOTORSPORT
- LOTUS 340R
