- This downpipe looks, fits and sounds great. If you want to go catless. I have this connected to the Gimmick motorsports catback, and the sounds and performance is awesome. It's quiet, but you still hear the deep boxer rumble. I highly recommend this DP.
- This is a Great downpipe and sounds awesome on My 04 sti. With the Cobb AP you feel great power all around. have it hooked up to an STP exhaust and made it twice as loud... Great product and great service by Importimageracing thanks
- I got this DP not soon after I got my CBE. It will get you a good gain w/ the AccessPort and bolts up easily to the Invidia N1 race CB. Sound is perfect. Welds are perfect, and so is the price. Cant go wrong with it in any way. Only thing is I recommend some new exhaust hangers to keep it a little tighter under the car..
- If your looking for a downpipe I would definantly consider this downpipe. As with any invidia product figment is perfect and quality is top notch. I've had this downpipe on my car for 3 years and never had a problem and no rust in sight. If you install any downpipe you have to get a tune or your motor can get screwed up! This with a tune makes one heck of a difference.
- Those of you looking to go catless, well look no further as this is your answer. This downpipe is wonderful, turbo spools way faster and you get some serious power gain (with proper tuning of course); Absolutely recommend it
- great sound. easy to install. turbo spolls way faster. i would recomend an ecm unit with this or any tbe (turbo back exaust);.
