Newly Released CXRacing Turbo Back Exhaust System For 84-91 BMW 3-Series with E30 Chassis, 6 Cyl, Convert to Top Mount T3 /T4 Turbo
3″ Stainless Steel Downpipe Catback V-band Clamp
This is CXRacing’s New Development, Completely New Design, Few of The Highlights: 
3″ Downpipe, V-band, with O2 Sensor 
3″ Catback System, 7″ Big Muffler With Deep Sound, 4.5″ Tip 
This Turbo Back System Fits perfectly with CXRacing’s Bolt on GT35 Turbo kit, Which Has The New Designed Manifold, Sits The Turbo a Little Bit Towards The Front. So For Other turbo Setups Or Other Manifolds, It Might Not Fit Correctly, Some Modification Is Needed. Due To Large Size Of The Package, We Will Only Do Exchange For Defected Product On Arrival (DOA), We Don’t Do Exchange If It Does Not Fit Your Application.  
The Catback Section Should Fit Fine, The Downpipe is The One Might Need Modification If You Have a Different Turbo Setup Than The CXRacing’s E30 GT35 Kit. 
We Developed A Few Products For The E30 And Fully Tested And Dyno. The Car We Used Is A 89 325I Stock Engine, Stock Fuel System. According to BMW, This Engine Produces 168HP and 166 ft-lbs When The Car Was Brand New. We Did Not Dyno The Car Before The Mod, But After Almost 20 Years In Use, We Estimate The Actual Power Is Around 125HP And 130 ft-lbs. These Are The #s We Got From Dyno: 
NA Header with 3″ Catback: 152 HP, 165 ft-lbs 
GT35 Turbo kit with 3″ Catback: 211 HP, 205 ft-lbs 
Check out Dyno Results and Videos from below pictures. 
These #s Are Very Good, Consider The Engine And Fuel System Is 100% Stock. We Believe With Proper Built Engine, Fuel System And Tuned, Our Turbo Kit Can Produce Around 400HP. NA Header Can Produce 180HP. 
Our Kit Has Been Fully Tested, Not Like Other Kits Offered On The Market, Many Of Them Are Universal Parts, None Of Them Work Nor Fit. We Develop Products With Actual Car And Even Consider Many Small Details, Such As The Intake Connector Of The Idle Control, Turbo Oil Restrictor. You Will Run Into Problems Without These Little Small Parts.  
Item(s) Included: 
3″ 304 Stainless Steel Downpipe Catback System 
3″ V-band Clamp Gasket
