Customer Questions & Answers
-
Question:
Will this exhaust kit fit my 2012 F-150 SVT Raptor?
Answer: Yes, this exhaust kit is designed to fit the 2011-2014 SVT Raptor models. -
Question:
Is installation easy for the average DIYer?
Answer: While installation is straightforward for a DIYer, modification may be required for certain models. -
Question:
What benefits can I expect from upgrading to this exhaust kit?
Answer: You can expect increased air flow, reduced back pressure, and a more aggressive sound. -
Question:
Will it fit a 2014 fx4 extended cab?
Answer: They have a kit for the extended cab. The description should list the bed length that it'll fit. -
Question:
Is this kit a side exit or straight out? I am looking for rear and not factory side exit. Thanks
Answer: Yes, this is the Roush 421248 rear-exit exhaust. -
Question:
Do you think this will fit a 5.4 raptor?
Answer: Not 100% sure the ford F150 raptor is not offered in a 5.4L. On my truck which is the 5.0 L it has a 3 inch exhaust and I know on the older 5.4 Triton's they have a 2 1/2 so it will not work.
Roush Cat-Back Systems 421248 Editorial Review
The Roush Performance Products 421248 Exhaust Kit has garnered a generally positive reception from customers looking to amplify the sound and performance of their Ford trucks, specifically Raptor and F-150 models. Many users report that installation is straightforward, allowing even those without extensive mechanical experience to manage the process within a short timeframe. One reviewer highlighted that the kit fits well with existing vehicle hangers, though some modifications may be required depending on the vehicle’s engine type—particularly with the 6.2 model where a different flange necessitates reusing the original part. Sound quality is a major draw for customers, many describing it as a satisfying "deep growl" that enhances the exhaust note significantly. However, some users expressed concerns regarding excessive cabin noise, particularly during cold starts, which can be quite loud and startling. Modifications such as adding a glass pack can help mitigate this issue, resulting in a more tolerable in-cabin experience while still allowing for enjoyable loudness when desired. Aesthetic aspects also received mixed reviews—while the black powder coating looks sharp, some customers noted that it may wear off over time with exposure to elements. Overall, customers appreciate the balance of sound performance and design, with a few Considerations for potential modifications to suit personal preferences. **
